Description:

t1lib is a library distributed under the GNU General Public Library
License for generating character- and string-glyphs from Adobe Type 1
fonts under UNIX. t1lib uses most of the code of the X11 rasterizer
donated by IBM to the X11-project. But some disadvantages of the
rasterizer being included in X11 have been eliminated. Here are some
of the features:
- t1lib is completely independent of X11 (although the program
provided for testing the library needs X11)
- fonts are made known to library by means of a font database file at
runtime
- searchpaths for all types of input files are configured by means of
a configuration file at runtime
- characters are rastered as they are needed
- characters and complete strings may be rastered by a simple function
call
- when rastering strings, pairwise kerning information from .afm-files
may optionally be taken into account
- an interface to ligature-information of afm-files is provided
- a program to generate afm-files from Type 1 font files is included
- rotation is supported at any angles
- there's support for extending and slanting fonts
- underlining, overlining and overstriking is supported
- new encoding vectors may be loaded at runtime and fonts may be
reencoded using these encoding vectors
- antialiasing is implemented using three gray-levels between black
and white
- An interactive test program called "xglyph" is included in the
distribution (as separate package). This program allows to test all of
the features of the library. It requires X11.
