NAME

  Imager::Font::Type1 - low-level functions for Type1 fonts

DESCRIPTION

Imager::Font::T1 is deprecated.

T1Lib is unmaintained and has serious bugs when built on 64-bit systems. Freetype 2 has Type 1 font support and is supported by Imager via Imager::Font::FT2.

Imager::Font creates a "Imager::Font::Type1 object" when asked to create a font object based on a ".pfb" file.

See Imager::Font to see how to use this type.

This class provides low-level functions that require the caller to perform data validation

By default Imager no longer creates the t1lib.log log file. You can re-enable that by calling Imager::init() with the "t1log" option:

  Imager::init(t1log=>1);

This must be called before creating any fonts.

Currently specific to Imager::Font::Type1, you can use the following flags when drawing text or calculating a bounding box:

"underline" - Draw the text with an underline.
"overline" - Draw the text with an overline.
"strikethrough" - Draw the text with a strikethrough.

Obviously, if you're calculating the bounding box the size of the line is included in the box, and the line isn't drawn :)

Anti-aliasing

T1Lib supports multiple levels of anti-aliasing, by default, if you request anti-aliased output, Imager::Font::T1 will use the maximum level.

You can override this with the set_t1_aa() method:

set_aa_level()

Usage:

  $font->set_aa_level(1);
  Imager::Font::T1->set_aa_level(2);

Sets the T1Lib anti-aliasing level either for the specified font, or for new font objects.

The only parameter must be 1 or 2.

Returns true on success.
