Font::TTF::Post(3)

💖 NAME 💖

Font::TTF::Post - Holds the Postscript names for each glyph. Okay bestie, this is the User Contributed Perl Documentation page for Font::TTF::Post(3), and it is literally the module that holds the Postscript names for each glyph. 💅

---

✨ DESCRIPTION ✨

So this module holds the postscript names for glyphs. Important vibe check: they are not held as an array — they are held as indexes into two lists. The first list is the standard Postscript name list defined by the TrueType standard. The second list 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. No cap.

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. (System drama, honestly.) 🙈

• $Font::TTF::Post::no25 — if set, this tells Font::TTF::Post::out to use table type 2 instead of 2.5 in case apps cannot 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. 🎀

$t->minsize()

Returns the minimum size this table can be. If it is smaller than this, then the table must be bad and should be deleted or whatever. 💀

💀 BUGS 💀

• No support for type 4 tables. 😭
