读写pdf文件的程序开发库源码,对于编写开发库有所帮助.

This directory contains a rasterizer for "Type 1" (PostScript) format
outline fonts.  It was donated by IBM for the R5 contrib tape and has
been maintained since then by the MIT X Consortium.  This version is
compatible with X11R5 public patch 13.

To be used, this rasterizer must be bound into the X server and the font
server.  It is most convenient to do this if this directory is moved
into the 'mit' directory tree (i.e., mit/font/lib/font/Type1, a peer of
the 'Speedo' directory).  Of course, mit/font/lib/font/Imakefile must be
made aware of its new subdirectory and the objects in it.  In any case,
you must ensure that the library mit/font/lib/font/libfont.a contains
this code.
 
In addition, the rasterizer must be "registered" with X. The source in
mit/fonts/lib/font/fontfile/renderers.c, specifically the routine
FontFileRegisterFontFileFunctions(), must be modified to add the line:
 
    Type1RegisterFontFileFunctions();
 
after the call to "SpeedoRegisterFontFileFunctions".
 
Some Type 1 fonts have been donated; see, for example, the directory
contrib/fonts/scaled/Type1.  In order to use them, they must be in the
font path, either by combining them in some existing font object
directory, or adding a new font directory to the path.
