This module draws Graphics::Primitive objects using Cairo.
Borders are drawn clockwise starting with the top one. Since cairo cant do
line-joins on different colored lines, each border overlaps those before it.
This is not the way Id like it to work, but im opting to fix this later.
Consider yourself warned.
Set/Get the antialias mode of this driver. Options are default, none, gray and
This drivers Cairo::Context object
Get the format for this driver.
Get/Set the surface on which this driver is operating.
Get the data in a scalar for this driver.
Write this drivers data to the specified file.
get_text_bounding_box ($font, CW$text, CW$angle)
Returns two Rectangles that encloses the
supplied text. The origins x and y maybe negative, meaning that the glyphs in
the text extending left of x or above y.
The first rectangle is the bounding box required for a container that wants to
contain the text. The second box is only useful if an optional angle is
provided. This second rectangle is the bounding box of the un-rotated text
that allows for a controlled rotation. If no angle is supplied then the
two rectangles are actually the same object.
If the optional angle is supplied the text will be rotated by the supplied
amount in radians.
Returns a Graphics::Primitive::Driver::TextLayout for the supplied
Reset the driver.
Draws the specified component. Containers components are drawn recursively.
