This are Text utilities for use with the GD drawing package. This
package provides three modules:
GD::Text:
Provides information about a font, irrespective of whether the font
is a TTF or builtin font.
GD::Text::Align
Align a string around a coordinate, left, right, center, top, bottom
or center.
GD::Text::Wrap
Wrap a long string between a right and left margin, starting at a
certain y coordinate. Layout the text flush left, flush right,
center, or justified.
Requirements:
perl 5.005_03 or higher, preferably 5.6. It may work on older
versions, but it has not been tested, and I won't spend a lot of
time trying to support it.
GD 1.20 or up, built for TTF (freetype) support.
Please note that the freetype version 2 libraries should be at
the latest level. Especially version 2.0.3 has an annoying bug
that rotates text twice.
Installation:
perl Makefile.PL
make
make test
make demo
make install
Demo(s) can be found in the demo directory.
DO NOT PANIC when the tests fail. The various Freetype libraries often
have a slightly different implementation of their rendering algorithms,
resulting in slightly different bounding boxes for strings, and slightly
diffferent looking images. If your tests fail, try a 'make demo', and
visually compare demo/GDWrap.png (freshly generated image) and
demo/GDWrap.ref.png (reference image). If they look reasonably similar,
you can call the tests successful. Even if they don't look entirely
similar, it may simply be because your font files are different from the
ones I used to create GDWrap.ref.png. Please see the sources.
Todo:
- Make the interface more flexible
- Alignment for the wrap boxes as a whole
- More demo code
