OpenOffice::OODoc::Styles - Document styles and layout processing



This class is designed to handle styles, whether automatic or named, contained in styles.xml or content.xml. It inherits from the common OpenOffice::OODoc::XPath class and brings style-focused features.

This class should not be explicitly used in an ordinary application, because all its features are available in the OpenOffice::OODoc::Document class, in combination with other features. Practically, the present manual is provided to describe the style processing features of OpenOffice::OODoc::Document (knowing that these features are technically supported by the OpenOffice::OODoc::Styles component of the API).

Remember that named styles are those that the end user can see and edit using through the GUI of an interactive office software (for ex. the Stylist tool in

Such styles usually have meaningful names and are stored in the styles.xml member. But an OpenDocument-compliant style may own two names, so-called ’name’ and ’display-name’. The ’display-name’ is the name as it’s displayed by the office software, while the ’name’ is the main identifier. Both are displayable character strings, but they often differ. For a given ’display-name’, the application software is allowed to set any arbitrary ’name’. For example, with 2, the well-known pre-defined style whose display name is Text body is named Text_20_body (the space character is replaced by its hexadecimal value between two _ characters). In the other hand, the ’name’ and the ’display-name’ generally don’t differ when they contain letters and/or digits only. Remember that the ’name’ (and not the ’display-name’) is the main identifier of a style element. So, such a method as getStyleElement(style name) uses the ’name’ attribute to retrieve a style descriptor and, in case of failure, it attempts to retrieve the same element by ’display-name’ (unless you change this behaviour through the ’retrieve_by’ document property).

Care should be taken particularly with predefined base styles in These styles are described in styles.xml just like named styles, but they appear to the end user with localised names (in their local language), so the really displayed style name is neither the ’name’ nor the ’display-name’ stored attributes. For example, in the French distribution of, the Text body style appears as Corps de texte, while its display-name is Text body and its name is Text_20_body. This localization is hard-coded in the office software for a few predefined styles, and it’s not stored in the file. However, this is not a problem for user-defined styles as the stored display-name is exactly the same as the effective display name.

There are also numerous automatic styles in a document which are created implicitly by the office application each time a particular set of presentation attributes is given to an element, but where no named style is referenced. Automatic styles which apply to the document body are stored in content.xml (but in an XML element isolated from the content). An automatic style’s name can change randomly each time the document is edited or saved through an interactive desktop application. Applications which access automatic styles will not want to indicate them using hard-coded names. The best way is to retrieve each automatic style via an object that is known to use it. Using a hard-coded name is all right for styles created by a program (the createStyle() method requires it), but such a name should only be considered to be stable for the duration of the session. If you want a program-created style name to be then respected by, you must create it as a named style. This is no more complicated, but it is better to avoid making hundreds of styles visible to the user that they do not need to see.

There are some structural differences between the old 1.0 format and the OASIS OpenDocument (ODF) one. A few of these differences aren’t made fully transparent by OpenOffice::OODoc. So, in some cases, a program including style definitions or updates doesn’t produce exactly the same results with both OOo 1 and ODF documents.

The page styles are more complex than the other usual styles. A page style Some styles are more complex than others as they describe the page layout. so called master page, can actually define a header, a footer, margins, and a background.

Page headers and footers can contain text and images; as a consequence, some of their features can be handled by OODoc::Text and OODoc::Image.

A background contains a colour and can also include a background image (several methods are possible).

Presentation of these objects is itself controlled by styles.

All of this leads to the conclusion that it is not enough just to associate each content element with a style. In reality, document styles form a rather complex network of interdependencies.

As for page styles, the OpenDocument format contains a concept which must be understood in order to use some of the following methods. By virtue of the principle of separation of content and presentation, the definition of a page style is based on two distinct objects: master page and page layout. A master page object encompasses any page style content (i.e. the content of headers and footers) and links to a page layout object which describes page presentation characteristics (with large numbers of parameters from page dimensions to background colour to footnote separator size, etc.). Names which appear in the list of page styles in are actually names of master pages. However, to work with physical aspects of the presentation, you have to access the associated page layout.

To complicate matters, there are also header and footer styles. Each object contained in a header or footer (e.g. paragraph or image) has a style. The number and range of styles are much larger that you would imagine just looking at the style management tool in any office software. Up to a point, OODoc::Styles methods make life easier for you by masking some of this complexity.

In OODoc::Styles methods, styles are normally indicated by their logical names (which must be unique), but, except where otherwise stated, they can also be indicated by their style element reference as well. Moreover, when a method is expecting a page layout as an argument but the programmer passes it a master page instead (whether by design or by mistake), it knows in most cases how to automatically select the associated page layout.

OODoc::Styles allows the applications to create new styles, and not only to update existing styles. However, defining a style requires a great many attributes. Some appear in code examples in this manual, but for a full list of possible attributes for each style, you must refer to the OpenDocument specification. As a consequence, building styles from scratch by program is not a recommended practice. It’s much more easy to create documents which all the needed styles through an ODF-compliant office software, and to use them as templates in the programs, knowing that it’s very easy to retrieve an existing style, to copy it and to re-use it (as is or customised) in new documents.

OODoc::Styles module is designed to allow applications to manipulate any style and even create new ones. It is not recommended, however, to use it to create a presentation entirely from code. Here again, it is better to start from document templates which already contain at least a blank of each required style.


Constructor : OpenOffice::OODoc::Styles->new(<parameters>)

        Short form: odfStyles(<parameters>)

        This constructor should not be explicitly used in ordinary applications
        knowing that all the features of the returned object are inherited by
        any Document object.

        See OpenOffice::OODoc::XPath->new() for common arguments.

        Returns an OODoc::XPath OpenDocument connector with additional
        style-aware features.
        The member loaded by default is "styles.xml" which gives access to
        named or automatic styles associated with the page layout. The
        "content.xml" part should be forced if the application is to work
        with styles associated with the document body (automatic styles

backgroundImageLink(page [, link])

        Allows you to check the background images link (if found) for the
        page style given as the first argument. If another link is given as
        the second argument, it replaces the existing link.

        See imageLink in OODoc::Image about links. Put more simply, a link
        is the address of the graphics file which corresponds to the
        physical content of the image. Even though the background image
        belongs to the "page layout", the first argument can also be either
        a "master page" or a "page layout".

        If the second argument "link" is given, its value replaces the
        existing link in the same way as with imageLink.


                ("Standard", "");

        If the page did not have a background image before the call, one is
        created. It must, however, be an external linked image (as in the
        above example), unless the link represents the internal address of
        an already loaded image. This method does not itself carry out any
        physical import of an image.

        See also importBackgroundImage.

createMasterPage(name, options)

        Creates a new page style. Options are:

            layout    => page layout name
            next      => next master page style name

        The association with a "page layout" allows you to associate a
        layout to the page. Otherwise the page will have a default layout.


                        layout  => pm1,
                        next    => Standard

        See the OpenDocument specification (or the Organizer tab in the
        "Format/Page" dialog box of if you want to know what
        a "Next Style" is. The optional "next" parameter simply gives the name
        of a "master page", which can be the one you are currently creating.

createPageLayout(name, options)

        Creates a new layout style (page layout) which can be used by a page
        style (master page). Options are the same as for updatePageLayout().

createPageMaster(name, options)

        See createPageLayout()

createStyle(name, options)

        Creates a new style of any type or class (depending on options) and
        returns its reference if successful.

        The first argument indicates the new style name which must be unique
        in the document. By default, there is no automatic uniqueness check.
        However, if a check option is set to true, the method
        fails and produces an error message warning if the style already exists.
        If the external name of the style, as it could be made visible for the
        end-user through an OpenDocument-compliant editing software (such as, is not the same as the internal name, it may be set
        through a display-name option. Without this option, the display name
        is the same as the internal name.

        If the active OODoc::Styles object is associated with a document
        content (content.xml), the new style is always taken to be an
        automatic style. If associated with the styles.xml part, the new
        style is considered to be a named style by default. However, the
        category => automatic option (or category => auto) allows you to
        specify it as an automatic style. Please note: in the case of
        content.xml, the "category" option is ignored as all styles are
        automatic in this member.

        By default, the method stores a style in the form of an XML element
        "style:style" (which corresponds to the most commonly used content
        styles). Some style elements are indicated in a different way. The
        "namespace" and "type" options are available for this. If, for
        example, you want to create a notes configuration style (called
        "text:notes-configuration" in the ODF specification), you will have
        to specify the "notes-configuration" type explicitly in the "text"
        namespace using one of the following two options:

            namespace           => text,
            type                => notes-configuration

        The possible options are:

            namespace           => namespace
            type                => style type
            family              => style family (text, paragraph, ...)
            class               => style class
            parent              => parent style (inherit)
            next                => next style

        If other style "organisation" attributes (often for links to other
        styles) prove to be needed but are not on the above list, they must
        be grouped together in a hash provided by the application and
        indicated by a "references" option.

        Of course, if you create a new style, you do not just specify it into
        terms of type, class or family, etc. You attribute its own
        presentation attributes which can be inherited by other styles which
        cite it as "parent". These personal attributes (whose nature obviously
        depends on the style type) are all attributed by the "properties"
        attribute which itself is a hash provided by the application.

        Here is an example of a paragraph style creation

                family  => paragraph,
                parent  => Standard,
                properties =>
                        fo:margin-left        => 2cm,
                        fo:margin-right       => 1.5cm,
                        fo:text-align         => justify,
                        fo:background-color   => #ffff00
            $doc->setStyle($doc->getParagraph(3), "P3");

        This sequence gives paragraph 3 of the document a special style
        whose properties are given margins, text justification and a
        yellow background color (note that the ODF color codes are in RGB
        hexadecimal preceded by a #, and ffff00 is the RGB value for
        for the yellow color). This is done using a style called "Colour"
        (reusable later for other paragraphs) based on the "Standard" style.
        The names of the properties can be found in the ODF specification
        (some of them come from the Form Object standard, so they begin with
        the "fo:" prefix). However, the given properties are related to the
        global layout of the paragraph. We could provide this new style with
        additional properties related to the text content of the paragraph.
        But, in a paragraph style definition, the "text" properties are not
        stored in the same logical area than the "paragraph" properties, and
        we cant set both in the same instruction. Fortunately, we can enrich
        any existing style at any time through the updateStyle() method:

                properties =>
                        -area                   => text,
                        style:font-name       => Times,
                        fo:font-size          => 14pt,
                        fo:font-weight        => bold,
                        fo:font-style         => italic,
                        fo:color              => #000080

        This new sequence gives paragraph 3 (or any paragraph using the
        "Colour" style) a lovely Times font in dark blue size 14 bold italics.
        The -area parameter which appears in the properties hash is not
        a property; its a selector which instructs the API to select the
        "text" property set.

        Note: the hexadecimal color codes used in the example could be
        replaced by more user-friendly color names, according to a standard or
        application-specific RGB color table, through the odfColor() function
        introduced in the present manual chapter.

        If the -area selector is omitted, the property set whose name is
        the name of the style family (i.e. paragraph in the last example).
        The -area selector is silently ignored when used with OOo 1
        documents, and sometimes required for ODF, so you can safely use it if
        you want to write portable code. In addition, up to now, the unknown
        style attributes are simply ignored by the software,
        and they dont harm. However, if the document is later edited and
        saved through, every unknown attribute is removed. As a
        consequence, everybody can use proprietary (non-OpenDocument) style
        attributes for application-specific markup.

        Another example:

                family  => graphics,
                parent  => Graphics,
                properties =>
                        style:vertical-pos    => from-top,
                        style:horizontal-pos  => from-left,
                        style:vertical-rel    => page,
                        style:horizontal-rel  => page,
                        draw:luminance        => 4%,
                        draw:contrast         => 2%,
                        draw:gamma            => 1.1,
                        draw:transparency     => 5%,
                        draw:red              => -3%,
                        draw:green            => 2%

        The "Photo1" style defined above is of course an image style i.e. in
        the "graphics" family, based on the parent graphics style
        "Graphics". Any images to which this style will be applied will have
        coordinates which relate to the upper left edge of the page measured
        from top to bottom and left to right. They will be presented with an
        increase in luminosity of 4% and contrast of 2%, gamma correction of
        1.1 and 5% transparency. Moreover, 3% less red and 2% more green
        will freshen the image and highlight the vibrancy of the
        chlorophyll. There are yet more in the list of options.

        Note: In the given examples, "namespace" and "type" are not specified
        because the default namespace and type are appropriate here. (Rest
        assured that this is often the case when working with text styles.)

        So, while OpenOffice::OODoc supports both OOo 1 and ODF with the
        same API, the present version cant completely hide the differences
        between the two formats. However, the programs logic can hide these
        differences for the end-user, because it can know the format of
        the current document (see isOpenDocument in OpenOffice::OODoc::XPath).

        Defining a style can be made a lot easier by reusing an already
        existing style than by creating it programmatically. The simplest way
        is by inheritance using the "parent" option, but the link to "parent"
        creates a permanent dependency (any further changes in the parent will
        affect the children). OODoc::Styles offers another possibility: copy
        the properties of an existing style, without creating a link to a
        parent, using the "prototype" option. This option points to another
        style whose properties are then taken up and combined with the new
        properties. New properties prevail over old ones if the new
        properties replace existing attributes in the prototype style, just
        like when they are inherited. But there is no persistent link from the
        new style to its prototype.


                prototype       => "Colour",
                properties      =>
                        fo:font-size  => 16pt

        This new style called "Bigger" is an exact copy of the previously
        defined "Colour" style, except for the font size.

        The given "parent" style is not necessarily defined yet and, if the
        current document part is "content", it can be the name of a style
        defined in the "styles" member. (See getAncestorStyle() and

        Generally speaking, explicit parameters passed by an application
        (e.g. font size) prevail over prototypes parameters.

        The prototype parameter can be a style name (as in the above
        example) or a style element. If its an element, its origin doesnt
        matter (it can be a copy of a style element previously extracted from
        another document). If its a name, the prototype style is retrieved
        either in the current document (default) or, if the source option
        is provided, in another document.
        The value of the source option is another OODoc::Styles (or
        OODoc::Document) object. If this option is provided, createStyle
        looks in the indicated document for the prototype style. If source
        is provided without prototype, the prototype style is supposed to
        have the same name as the style to be created.
        If you want to create a style called "MyStyle", for example, in
        document $doc1 which imitates a style called "HisStyle" in document
        $doc2 (where both documents are OODoc::Styles or OODoc::Document
        objects), you can do the following:

                        prototype       => "HisStyle",
                        source          => $doc2
        but if you write
                        source          => $doc2
        the local style "MyStyle" is built as a copy of the so-named style
        in the source document (its a direct import).
        Whatever the origin of the prototype style, any property can be
        set or redefined in the new style.

        Not only can you import styles available in other documents, but
        you can also create automatic styles in a content part which
        are derived from named styles found in the styles member and

        WARNING: The "prototype" option can produce unexpected results if
        the two documents are not in the same format. As a consequence,
        using an OOo 1 style as the prototype of an OpenDocument one (and
        vice-versa) should be avoided.

        Always be careful of dependencies. There are often dependencies
        between styles. An application must be wary of importing styles with
        directly or indirectl dependencies on other styles which will not be
        available in the target document. Text styles are fairly easy to
        control in this way, but table, page and graphic styles, for example,
        have more complex dependencies.

        When a font name is set (generally through a style:font-name
        text property) in a new style, take care of the availability of
        the corresponding font declaration in the document. A font is not
        rendered if its not declared (see importFontDeclaration()).
        See the OpenDocument specification (chapter 14, "Styles") for a
        complete list of possible attributes for each type of style.
        However, creating sophisticated styles from scratch is *not*
        recommended; remember the most easy (and the less error-prone) way
        consists of creating template documents through the
        GUI (or any other ODF-compliant office software) and using them as
        style libraries.

exportBackgroundImage(page [, destination])

        Exports the graphics file which corresponds to the background image
        of a page style where the image exists and is internal to the archive. (A linked image is obviously not exportable
        since it is not actually present in the document.) See the
        exportImage method in OODoc::Image for export details.


                ("First Page", "C:\Images\backgrnd.jpg");


        Returns the name of the primary known ancestor of the given style.

        If the style has a standalone definition (i.e. its its own ancestor),
        the method returns its own name.

        This method returns the ancestor name as its known in the current
        document space. The genealogy is not followed out of the scope of
        the current XML part.
        For example, if we have an automatic paragraph style "P1", defined in
        the "content" member and derived from "Text body", the returned
        ancestor name will be "Text body". However, "Text body" itself could
        be a derivative of "Standard". But "Text body" is defined in the
        "styles" member, so its definition (including the name of its parent
        style) is out of the scope.

        As a consequence, in a regular ODF document, there are 2 possible

        - if the current space is "styles", the returned style name is really
        the name of the primary ancestor, because a style defined in this
        space cant inherit from anything elsewhere;

        - if the current space is "content", the returned value can be the
        name of a style defined elsewhere.

        A possible check is a simple call to getStyleElement() with the
        returned ancestor name. If getStyleElement() returns undef, then
        the ancestor style is not defined in the current space (and, if
        needed, we could reach it the "styles" member, if we currently work
        with the "content" member).

        Beware: the returned name is the main name (identifier), and not the
        display name.

        See also getParentStyle().


        Returns a list of automatic style elements in the current document.
        By default, only "style" type elements in the "style" namespace are
        returned. You can select special styles using the "namespace" and
        "type" options.

        For example, if you want to get a list of number styles (namespace
        "number", type "number-style"), do it like this:

            my @styles = $doc->getAutoStyleList
                (namespace => number, type => number-style);


        Returns the element that contains all the automatic style elements.
        See also getNamedStyleRoot().


        Returns the attributes of the given page styles background image
        (if any), in the form of a hash (attribute => value).


        Returns the element reference of the given page styles background
        image (if found).


        Returns the given default styles attributes (if any). Default
        styles are generally "paragraph" and "graphics". See also


        Returns the default style elements reference given by its logical

        A default style describes default values assigned to certain
        attributes of a given style family.

        For example, to get the default paragraph style of a document, use:

            my $def_para = $doc->getDefaultStyleElement("paragraph");


        Returns the font declaration element corresponding to the given font
        name, or undef if the font is not declared in the current document.
                unless ($doc->getFontDeclaration("Times New Roman"))
                        $doc->importFontDeclaration($doc2, "Times New Roman");

        See also importFontDeclaration().


        Returns the full list of the font declaration elements present in
        the document.

        The following example prints every declared font name:

                foreach my $fd ($doc->getFontDeclarations)
                        print $doc->getFontName($fd) . "\n";


        Returns the name of the given font declaration element.

        Returns the argument as is if this argument is the name of a declared
        font, or undef if the name is unknown.

getFooterParagraph(masterpage, number)

        In a text document, returns a footer paragraphs reference, if the
        master page has a footer and the paragraph exists. Arguments are
        master page and paragraph number.
        Caution: the first argument cant be a page number, knowing that
        printable pages are dynamically created by the office software and
        dont exist in the stored document.

getHeaderParagraph(masterpage, number)

        Like getFooterParagraph, but for a header.


        Returns a master page element reference whose logical name is given,
        or undef if the page style is not found. You can also pass an
        element reference instead of a name. In this case, the methods role
        is simply to check if the element is indeed a master page type. If
        so, it returns the argument as is. If not, it returns undef.
        Look at the DESCRIPTION part of the present manual chapter for a few
        explanations about master pages (and, of course, feel free to dig in
        the OpenDocument specification for details).
        This method should preferently be used on the styles member; it
        doesnt generally make sense with the content member, knowing that
        the master pages are generally described as named styles.


        Returns a list of master styles in the current document. By default,
        the list contains the master page elements.
        Other kinds of styles may be retrieved, according to the namespace
        and/or type options (see getStyleElement()). But the search space
        is limited to the master styles area, whatever the type and the

        Like getMasterPageElement(), this method makes more sense on styles
        members than on content ones.


        Like getNamedStyleRoot(), but the returned element contains the
        master style descriptors instead.


        Returns a list of named styles in the current document, using the
        same options as for getAutoStyleList. By definition, in documents this list should be empty in all elements
        except styles.xml.


        Returns the root element of the named styles area. In other words,
        this method retrieves the element that contains all the named style
        elements, with the exception of the master styles.
        This element could be, for example, copied from a document to another
        one in order to use exactly the same named styles (user-defined or
        provided with the office software) in both.


        Returns the outline style descriptor related to the given outline
        level. The returned element is available for subsequent get/set
        operations using getAttributes(), setAttributes(), and so on.
        See also updateOutlineStyle().


        Returns the description of a page layout. The argument can be
        either a page layout directly or a master page style which
        refers to it.

        The structure of returned data is a hash of hashes. It contains four
        elements, each of which is a hash. As follows:

            - "references": style reference attributes with at least its
            name and possibly its links to other styles.
            - "properties": background description (dimensions, orientation,
            margins, colour, etc.).
            - "header": presentation attributes for the header.
            - "footer": presentation attributes for the footer.
            - "footnote-sep": footnote separator attributes.
            - "background-image": background image attributes.

        Attributes are displayed according to specifications.


        See getPageLayoutAttributes()


        Returns the page layout element reference from a search argument
        which can be either a logical name or a page style reference. If the
        argument is a master page, the method returns the corresponding page


        See getPageLayoutElement()


        Returns the name of the parent of the given style, or undef if the
        style has a standalone definition (without inheritance). The returned
        name, if any, is the identifier of the parent style, which can differ
        from its display name.

        The returned parent name can be the name of a style defined elsewhere
        (or not defined yet).

        See also getAncestorStyle().


        Returns a styles description (other than a page style) given as a
        logical name or reference.

        The structure of returned data is a hash of hashes. It contains the
        two following elements:

            - "references": style reference attributes with at least its
            name and possibly its links to other styles (either its family,
            parent style, class and/or next style).
            - "properties": description of the presentation characteristics
            for this style (and which depend on the type of object the style
            is applied to).

        Remember that this structure can be used directly by an application
        to create or update another style.

getStyleElement(style_name [, options])

        Returns a style elements reference using its name, or undef if
        no style owns the given name in the current context. Remember that
        a style can be used in the content context while its descriptor
        (i.e. the style element) is defined in either the styles context
        or the content one. If the application doesnt know where the
        needed style is defined, it must call getStyleElement() in both.

        If the first argument is already an element reference, it returns
        the argument if it is indeed a style element, and undef if not, so
        this method could be used in order to check if a given element is
        a style element or not.

        By default, the style name is sought amongst "style" type elements
        in the "style" namespace. If an application is looking for a special
        style (e.g. page or number), then it can pass the optional
        parameters "namespace" and/or "type". See the section on createStyle
        for these concepts.

        A search is of course limited to automatic styles if the current XML
        document is "content". If the document is "styles", the search for the
        name is made in all styles by default. You can, however, limit it
        with the "path" parameter where "path" equals "auto" to search in
        automatic styles or "named" in named styles.
        The name is a mandatory property, and the main identifier of any style
        in ODF-compliant documents. But an additional property, so-called
        display-name, is sometimes provided by the applications. The
        display-name property, if provided, is made visible for the end user
        by the office software (for example in the stylist box of while the primary name is hidden. By default,
        getStyleElement() looks for a style whose primary name matches the
        given name, then, if the query fails, it tries to retrieve the style
        according to its display name. However, if the "retrieve_by" property
        of the connector is set to display-name, the display name becomes
        the preferred identifier.

        If a "retry" parameter is provided and set to "false" or any other
        value than "1" or "true", no double query is done. In other words,
        if the first query (by primary name or by display name, according to
        the value of the "retrieve_by" property of the connector) fails, the
        method returns immediately without trying any other query. The default
        value is "1" (true). You should set it to "0" or "false" in order to
        save some computation time if, for example, your application doesnt
        need to take care of the possible differences between display names
        and internal names.


        Combines the results of getAutoStyleList and getNamedStyleList (same

importBackgroundImage(page, filename [, link])

        Imports a background image into the given page style from an
        external file.

        The page style can be either a page layout or a master page. An
        optional link can be inserted (e.g. to reuse an existing link). See
        backgroundImageLink or imageLink (in OODoc::Image) for information
        about links. Otherwise, an internal link under "Pictures/" is
        created by default and takes the name of the source file.

        Returns the link if found, undef if not.

        Caution: the actual import is not made until a save is called (see
        importImage in OODoc::Image).

importFontDeclaration(doc, fontname)


        In the first form, retrieves a font declaration in another document
        and installs it in the current document. The first argument is a
        OODoc::Styles or OODoc::Document object.
                my $source = odfDocument
                        file => "source.odt", part => "styles"
                my $target = odfDocument
                        file => "target.odt", part => "styles"
                $target->importFontDeclaration($source, "Helvetica");
        In the second form, the single argument is the XML string
        containing a font declaration.

        The following example creates a declaration for the "Comic Sans MS"
        font in an OpenDocument:
                    <style:font-face                          .
                        style:name="Comic Sans MS"            .
                        svg:font-family="Comic Sans MS"        .
        This last import feature is not mainly provided in order to encourage
        raw XML coding! Be careful, the XML font declaration syntax is not
        exactly the same with the two supported document formats. This feature
        should be used in order to import previously exported font declarations
        (see exportXMLElement in OODoc::XPath).  
        A font declaration must be imported if its used in a newly
        created style and not currently available in the target document.

masterPageExtension(page, extension_type [, element])

        This method allows the user to get or set an extension to an existing
        master page. The most used extensions are "header", "footer",
        "header-left", "footer-left", but any other key could be provided
        (warning: there is no ODF-compliance check, so any application-
        specific tag is allowed, knowing that any provided keyword will be
        automatically prefixed by "style:" in the generated XML).
        See masterPageFooter(), masterPageFooterLeft(), masterPageHeader(),
        masterPageHeaderLeft(); these methods can be regarded as synonyms
        for masterPageExtension() with the four listed extension types.

masterPageFooter(page [, element])

        Returns the given page styles footer element reference (master
        page) or undef if not found.

        If the second argument is a content element, it is added to the
        footer. If the footer does not exist, it is created.

masterPageFooterLeft(page [, element])

        Returns the given page styles footer left element reference (master
        page) or undef if not found.
        A "footer left" element can be used to specify different content for
        left pages, if appropriate. Unless a footer left element is defined
        in the master page, the content of the footers on left and right pages
        is the same.

        If the second argument is a content element, it is added to the
        footer. If the footer does not exist, it is created.

masterPageHeader(page [, element])

        Returns the given page styles header element reference (master
        page) or undef if not found.

        If the second argument is a content element, it is added to the
        header. If the header does not exist, it is created.

masterPageHeaderLeft(page [, element])

        Returns the given page styles header left element reference (master
        page) or undef if not found.
        A "header left" element can be used to specify different content for
        left pages, if appropriate. Unless a header left element is defined
        in the master page, the content of the headers on left and right pages
        is the same.

        If the second argument is a content element, it is added to the
        header. If the header does not exist, it is created.

pageLayout(master_page [, page_master])

        Returns or modifies the layout of a given page style (master page).
        If the second argument is given, it replaces the old page layout value
        (i.e. it changes the layout of the page without changing the header or
        footer content.

pageMasterStyle(master_page [, page_master])

        See pageLayout()

removeStyleElement(style [, options])

        Deletes the given style. The argument and options are the same as
        for getStyleElement. The method returns "True" (1) if successful or
        undef if the style is not found.

selectStyleElementByFamily(family [, options])

        Returns the first (or only) available style in the given family
        (using the "family" attribute), or undef if not found. Options are
        the same as for getStyleElement.


            my $style = $doc->selectStyleElementByFamily
                        type    => default-style

        selects the element which describes the default graphic style.

        This method is useful for selecting styles whose "family" attribute
        is their identifier (and which do not have a "name" attribute). For
        example, this is the case for default styles where there is normally
        a default style for the "paragraph" family and another for the
        "graphics" family. In the above example, we used the "type" option
        where the type is "default-style" and not "style". We did not use
        the "namespace" option because it would be pointless to know that
        the default style namespace is just the default namespace ("style").

selectStyleElementsByFamily(family [, options])

        Like selectStyleElementByFamily but returns a list of elements which
        belong to the given family. The "family" argument is treated as a
        regular expression, so an application must therefore give the
        appropriate meta-characters if the search is to be limited to the
        exact family name.

selectStyleElementsByName(name [, options])

        Returns a list of styles whose names match the first argument (which
        is treated as a regular expression). Options are the same as for the
        other selectStyleElementsXXX methods.

setBackgroundImage(page, options)

        Inserts or replaces a background image in a page style. The "page"
        argument points either to the page layout directly, or to the master
        page to which it refers. Options point to the graphics object and
        how it is presented. The returned value is the created or modified
        background images element reference (see

        You should first indicate the graphics file which contains the image
        and whether it will merely be linked to the page by reference, or if
        it has to be physically imported into the file. To
        "link" the image, you supply its address using the "link" option. To
        import it, you supply the image using the "import" option.


                "First page",
                import          => "C:\Images\Logo.jpg"

                "First page",
                link            => "C:\Images\Logo.jpg"

        These two calls produce the same effect, but the second only inserts
        a link to the image.

        Remember that if by error an application supplies both the "link"
        and "import" options, the "import" option is the one that prevails.

        The other options control the import of images as backgrounds. By
        default, OODoc::Styles installs the image in the center without
        tiling and with an automatic update-on-load attribute if the image
        is by external link. You can choose other options using the standard vocabulary.

        To link a background image which is stretched to fit the entire
        page, use the following:

                "First page",
                link            => "C:\Images\back.jpg",
                style:repeat  => stretch

styleName(style_element [, name])

styleName(name [, options])

        The first form checks that the given argument is indeed a "style"
        element reference and, if it is, returns its name (undef if not). If
        a name is given as the second argument, it replaces the style name.

        In the second form, the current style name is given. In this case,
        and without any other arguments, the method only checks if the given
        name is indeed a style and returns a positive result (undef if not).
        It is still possible to change its name using this form, by using
        the "newname" option. With this form, some other options allow you
        to choose the namespace, type and category (automatic or named).
        These options are "namespace", "type" and "category" (see
        getStyleElement for these concepts). Without these parameters, the
        default values are the same as for getStyleElement.

        Beware: the only recognized style name here is the main style name,
        which can differ from the display name.

styleProperties(style [, options])

        This method is for checking and updating the formatting properties
        of a given style.
        It is more limited than updateStyle, but easier to code. The
        styleProperties method accesses only the styles formatting
        attributes and does not touch its references, such as its name, class
        or family (see getStyleAttributes).

        With no options, the current styles properties are simply returned
        in the form of a hash in which the keys are attributes belonging to
        the standard vocabulary and which depend on the type
        of object. The same data structure can be used to modify a styles
        properties by passing options as a hash. This structure is the same
        as the sub-hash "properties" of getStyleAttributes or updateStyle.
        If you wanted to redo the style we called "Colour" (see createStyle),
        for example, changing the colour of the characters to red and
        replacing the italics with standard font, you could do it as follows:

                        -area         => text,
                        fo:color      => odfColor("red"),
                        fo:font-style => undef

        This short sequence sets the "fo:color" attribute to red and clears
        the "font-style" attribute. Remember that in RGB notation, the
        quantity of red is given by the first two hexadecimal digits, which
        here are set to maximum, and by setting the green and blue to zero.
        The "font-style" attribute had previously been set to "italic".
        Here, the area option is neutral if the document format is OOo,
        but it must be set to text for an ODF document, because all that
        is related to characters belongs to the text area in a paragraph
        style (see below).

        styleProperties returns all the styles properties but only modifies
        those that have been set using options. To clear an existing
        property without giving it a new value, you must pass the
        corresponding option giving it a null value.

        If the current document is an OASIS Open Document, an additional
        "-area" option should be provided, because a styles properties may
        be stored in logical parts. For example, in a paragraph style, some
        properties apply to the paragraph itself, while some other ones apply
        to its text content (and some text properties can have the same name
        as some paragraph properties). The default value is the name of the
        style family. For example, if the style family is "paragraph", the
        "paragraph" part is selected by default. Because it updates font
        attributes (that are text properties), the example above couldnt
        work against an Open Document without an additional "area" option
        with the appropriate value:

                        -area         => text,
                        fo:color      => "#ff0000",
                        fo:font-style => undef

        After creating a new paragraph style in an Open Document, this method
        should be used in order to set the properties which have not been set
        by createStyle because of the separation in two areas. In the
        following example, the paragraph properties are directly set with
        createStyle, then the text properties are set with styleProperties:
                my $style = $doc->createStyle
                        family          => paragraph,
                        parent          => Standard,
                        properties      =>
                                -area                 => paragraph,
                                fo:text-align         => center,
                                fo:margin-left        => 0.5cm,
                                fo:margin-right       => 0.5cm
                        $style, -area => text,
                        fo:color              => oo2rgb("blue"),
                        fo:font-weight        => bold,
                        style:font-name       => Times New Roman
        Note: According to the OASIS OpenDocument v1.0 specification,
        any arbitrary custom attribute could be created in anyone of the
        styles properties area, and *should* be preserved by conforming
        applications when editing the document. However, up to now, any
        custom property is lost as soon as the document is edited through
        The "-area" option is silently ignored with OOo 1 documents.


        Switches a portrait page to landscape and vice-versa.

        The argument is a page style (page layout or master page).

        portrait and landscape are not style properties. The logic of
        this method is very simplistic: it makes a swap between the height
        and the width of the page.

        CAUTION: dont try to give a page number as the argument. This
        method apply on a page style (i.e. master page) and not on a
        real page selected by its number.

updateDefaultStyle(family, options)

        Modifies the default style for the given family according to an
        options hash given by the application. The family is generally
        "paragraph" or "graphics".

        Options are given according to the style attributes

        The following example shows how to change the font, font size and
        default tab stops in the text:

                fo:font-name                  => Helvetica,
                fo:font-size                  => 10pt,
                style:tab-stop-distance       => 1.5cm

updateOutlineStyle(level, properties)

updateOutlineStyle(outline style element, properties)

        Allows any change in the direct attributes of an outline style.
        The new properties must be provides through a hash, where each key
        is an OpenDocument-compliant attribute.
        The following example changes the numbering prefix and suffix, and
        the numbering format for the level 1 list elements, so their numbering
        will look like "[A] ", "[B] ", "[C] ", ...
                        num-prefix            => "[",
                        num-suffix            => "] ",
                        num-format            => "A"
        See the OpenDocument specification for the full set of possible
        attributes. Any attribute provided without namespace prefix (i.e.
        not including a :), such as those in the example above, are
        automatically prefixed by style:; other attributes must be provided
        with their prefixes.
        Caution, some outline presentation characteristics, such as bullet
        style, are not directly under the control of this element. They depend
        on children "style:*-properties" elements.

updatePageLayout(page, options)

        Modifies all types of page presentation style characteristics (page
        master). The style given as the first argument can be either the
        appropriate page layout style directly, or a page style (master
        page) to which it refers.

        Options can be passed in the form of a hash of hashes (each option
        itself points to a hash containing the base attributes). The four
        top-level elements are as follows:

            references          => name, family, etc.
            properties          => global presentation attributes
            header              => header presentation style
            footer              => footer presentation style
            footnote-sep        => footnote separator style
            background-image    => backgrnd.jpg image characteristics

        The "references" branch will not generally be used unless you want
        to change the styles name.

        This data structure is the same as returned by
        getPageLayoutAttributes(). A combination of these two methods allows
        you to copy the characteristics of one page style to another easily,
        especially when you want to apply the page setup of one document to
        another. When you only want to modify an existing style however, you
        only need to specify the attributes which you want to change.

        A "prototype" option allows you to clone the characteristics of an
        existing page layout. This option can indicate either an existing
        page layout reference, its logical name, or even the reference or
        logical name of a master page which refers to it. Only the first
        method is supported if the prototype page layout belongs to another
        document. The style name is not replaced by the prototype style
        name. See also createStyle about using a prototype style.

        The following example shows the code required to change several
        properties of the "Right page" style i.e. top margin width,
        background colour, maximum footnote height, minimum header height
        and the colour and width of the footnote separator.

                "Right page",
                properties      =>
                 fo:margin-top                => 2.5cm,
                 fo:background-color           => #88eecc,
                 style:footnote-max-height    => 3cm
                footnote-sep  =>
                 style:width                  => 0.02cm,
                 style:color                  => #0000ff
                header          =>
                 fo:min-height                => 2cm

        Once again, it is better to start with a getPageLayoutAttributes()
        of an existing page than to create all your styles from code.

updatePageMaster(page, options)

        See updatePageLayout()

updateStyle(style, options)

        Modifies the characteristics of an existing style.

        Options are the same as for createStyle() except for "category",
        "namespace" and "type" which cannot be changed in an existing style
        since they form part of its basic identity. A styles logical name
        can, however, be changed.
        The first argument can be either a style name or a style element.
        The second way should be preferred when the program already owns
        the element (obtained, for example, through getStyleElement() or

        In the properties structure, the area switch is required with
        ODF (OOo 2) documents if the property area is not the default one
        (see styleProperties and createStyle about the area option).

        You can use the "prototype" option to update a style with another
        styles characteristics, but this option does not replace the
        styles name with the prototypes name. Be careful, the "prototype"
        option doesnt work for any kind of style, and its not recommended
        in this method. The best approach for replicating an existing style
        consists of creating a new style with the "prototype" option (see

        By definition, the style already exists and can be indicated equally
        well by reference or by name.

        Returns the characteristics of the modified style, as in

    Exported functions

odfColor($red, $green, $blue) =head3    odfColor($red,$green,$blue) =head3      odfColor($colorname)

        Converts an RGB or named colour in ODF-compliant hexadecimal format
        (6 digits after a leading #). The 1st form has the same effect as
        the rgb2hex() function of the Color::Rgb Perl module.

        The resulting value can be used to set any colour attribute in a

        In the first form, the 3 arguments are the conventional numeric RGB
        values (between 0 an 255). In the second form, the only one argument
        is a string containing 3 comma-separated RGB values. In the third
        form, the given string is the symbolic name of a colour (the name
        must be an existing one in the %COLORMAP hash).


                        fo:color              => odfColor(black),
                        fo:background-color   => odfColor(yellow)
        If the argument seems to be already an hexadecimal RGB string (i.e.
        it begins by "#"), odfColor() checks it and returns it unchanged if
        its a regular RGB value, or undef if not.

        Synonym: rgb2oo().


        Populates the %OpenOffice::OODoc::Styles::COLORMAP hash from the
        content of an RGB file. This file defines a colour dictionary.
        Without argument, the content of the $COLORMAP variable is considered
        as the filename.

        Each line must contain 4 space-separated fields. The 3 first fields
        represent, respectively, the red, green and blue values of a colour
        and must be positive integer values in the 0-255 range. The remainder
        of the line is considered as the symbolic name of a colour (it can
        contain spaces). Example:

                144 238 144     light green
                139   0 139     dark magenta
                255 105 180     hot pink
                255  99  71     tomato

        Such a file is sometimes provided in a system directory (for example
        /usr/lib/X11/rgb.txt in some Unix systems). In any case, the users
        can easily find and download it somewhere. For example, a convenient
        rgb.txt file is provided with the Color::Rgb Perl module (CPAN).

        When a COLORMAP is loaded, the programmer can provide symbolic, user-
        friendly names in place of RGB values to the odfColor() function.
        Without argument, the content of the $COLORMAP variable is considered
        as the filename.

        When the OpenOffice::OODoc::Styles module is loaded as a consequence
        of a "use OpenOffice::OODoc" statement, ooLoadColorMap() is
        automatically executed if a valid filename is provided in the
        <Styles-COLORMAP> element of the "OODoc/config.xml" file.


        Returns the conventional RGB value of an OOo-encoded colour.

        See rgbColor().


        Synonym of odfLoadColorMap().

rgb2oo($red, $green, $blue) =head3      rgb2oo($red,$green,$blue) =head3        rgb2oo($colorname)

        See odfColor().


        Converts an ODF-color code into a decimal RGB code or, according
        to a mapping file, into a plain text conventional color name.

        In array context, returns a 3-element array containing the red, green,
        blue decimal values of the colour.

        In scalar context, returns either a string with concatenated, comma
        separated red, green, blue values, or, if these values exactly match
        a known colour (according to the current %COLORMAP), the corresponding
        symbolic name.

        This function can be used to display or compute separately the RGB
        values of any colour attribute of a style, or to export these values
        to an image processing software. It produces the same result as the
        hex2rgb() method of the Color::Rgb Perl module.

        rgbColor() is a synonym of oo2rgb().


        The retrieve_by option, set to display-name, can be provided
        in order to use the display name instead of the primary name as
        the first style identifier.

        The %COLORMAP hash, defined as a class variable, contains a name
        to RGB translation table. When loaded, it allows the rgb2oo() function
        to use symbolic names in place of RGB values.
        The keys are symbolic, user-defined colour names, and the values are
        strings containing the concatenated, comma-separated RGB values.


        %OpenOffice::OODoc::Styles::COLORMAP{antique white} = "250,235,215";

        By default, this hash contains a short, arbitrary set of colour
        definitions such as red, green, blue, white, black and a few
        others. The user can populate it from an external RGB file, through
        the ooLoadColorMap() function previously described, and/or through
        program instructions like the example above.
