Post Scriptum 1.0-beta (Default branch)
09-14-2008
Post Scriptum is a programming language forpreparing PostScript documents and programs. Thelanguage is procedural, and uses classical controlstructures (functions, loops, and conditionalstatements) and commonly known data types(numbers, arrays, strings, and dictionaries). Itssyntax is simple, clear, and easy to learn. Thecompiler translates programs written in PostScriptum directly to a PostScript file, which canbe than executed by a PostScript interpreter (suchas Ghostscript), printed, or used as a procset,driver, or library.License: GNU General Public License v2Changes:|

Font::TTF::Post(3pm) User Contributed Perl Documentation Font::TTF::Post(3pm) NAME
Font::TTF::Post - Holds the Postscript names for each glyph DESCRIPTION
Holds the postscript names for glyphs. Note that they are not held as an array, but as indexes into two lists. The first list is the standard Postscript name list defined by the TrueType standard. The second comes from the font directly. Looking up a glyph from a Postscript name or a name from a glyph number is achieved through methods rather than variable lookup. This class handles PostScript table types of 1, 2, 2.5 & 3, but not version 4. Support for version 2.5 is as per Apple spec rather than MS. The way to look up Postscript names or glyphs is: $pname = $f->{'post'}{'VAL'}[$gnum]; $gnum = $f->{'post'}{'STRINGS'}{$pname}; INSTANCE VARIABLES
Due to different systems having different limitations, there are various class variables available to control what post table types can be written. $Font::TTF::Post::no25 If set tells Font::TTF::Post::out to use table type 2 instead of 2.5 in case apps can't handle version 2.5. VAL Contains an array indexed by glyph number of Postscript names. This is used when writing out a font. STRINGS An associative array of Postscript names mapping to the highest glyph with that name. These may not be in sync with VAL. In addition there are the standard introductory variables defined in the standard: FormatType italicAngle underlinePosition underlineThickness isFixedPitch minMemType42 maxMemType42 minMemType1 maxMemType1 METHODS
$t->read Reads the Postscript table into memory from disk $t->out($fh) Writes out a new Postscript name table from memory or copies from disk $t->XML_element($context, $depth, $key, $val) Outputs the names as one block of XML BUGS
o No support for type 4 tables AUTHOR
