In this manner a font may map some of its glyphs to the standard glyph names, and some to its own names.

If the name index is between 27, then subtract 258 and use that to index into the list of Pascal strings at the end of the table. If the name index is between 0 and 257, treat the name index as a glyph index in the Macintosh standard order. The glyph name index array in this subtable maps the glyphs in this font to a name index. 'post' Format 2įormat 2 is used for fonts that contain some glyphs not in the standard set or whose glyph ordering is non-standard. Fonts with the Euro cannot use 'post' formats 1 or 2.5.

Font vendors should update their fonts as possible to include the Euro for proper functioning on OS X 8.5 and later.

The standard Macintosh ordering of glyphs was not updated, however, in order to avoid breaking fonts and software that used it. When OS X 8.5 was released, the MacRoman character set was redefined to replace the Universal Currency Symbol with the Euro. The names for these 258 glyphs are, in order: Glyph ID As a result, this format does not require a special subtable. For such fonts, the glyph names are taken from the system. The order in which glyphs are placed in a font is at the convenience of the font developer To use format 1, a font must contain exactly the 258 glyphs in the standard Macintosh ordering. Minimum memory usage can be calculated by calling VMStatus, downloading the font, and calling VMStatus a second time. The memory usage of a downloaded TrueType font will vary with whether it is defined as a TrueType or Type 1 font on the printer. Runtime memory usage could be calculated by rendering characters at different point sizes and comparing the memory use. Maximum runtime memory use depends on the maximum band size of any bitmap potentially rasterized by the TrueType font scaler. Maximum memory usage is minimum memory usage plus maximum runtime memory use. If it is not known, set the values to zero. This information should be supplied if known.

The entries minMemType42, maxMemType42, minMemType1, and maxMemType1 are necessary because PostScript drivers can do better memory management if the virtual memory requirements of a downloadable TrueType font are known before the font is downloaded. Note that on OS X, it is also necessary to make sure that glyph widths from 'NFNT' bitmap fonts are consistent with the monospaced metrics in the TrueType font. A monospaced font will also have to have the maximum width field in the 'hhea' table set appropriately. A monospaced font is one in which all glyphs have the same horizontal width at all point sizes (that is, in the 'hmtx' and 'hdmx' tables), or have zero width. The isFixedPitch flag is used to indicate that the font is monospaced. Maximum memory usage when a TrueType font is downloaded as a Type 1 font Minimum memory usage when a TrueType font is downloaded as a Type 1 font Maximum memory usage when a TrueType font is downloaded as a Type 42 font Minimum memory usage when a TrueType font is downloaded as a Type 42 font Only formats 2, 2.5 and 4 require subtables.įont is monospaced set to 1 if the font is monospaced and 0 otherwise (N.B., to maintain compatibility with older versions of the TrueType spec, accept any non-zero value as meaning that the font is monospaced) There are five possibilities: format 1, format 2, format 2.5, format 3 and format 4. The first item specifies the table format. The 'post' table is documented in Table 72 below.

It also contains memory usage information needed by the PostScript driver for memory management. It contains the data needed for the FontInfo dictionary entry as well as the PostScript names for all of the glyphs in the font. The 'post' table contains information needed to use a TrueType font on a PostScript printer. The 'post' table General table information
