150 ) Appendix (KRN O 177 R 0.056) (KRN O 75 R -0.056) (KRN O 73 R -0.083) (KRN O 72 R -0.083) ) (MAP (SETCHAR C W) ) The next specification is a combination of two other glyphs becoming a new glyph. We see here that the MAP table is actually a sort of program: (CHARACTER O 200 (CHARWD R 0.622) (CHARHT R 0.691) (MAP (PUSH) (MOVEDOWN R -0.18) (MOVERIGHT R 0.015) (SELECTFONT D 2) (SETCHAR O 40) (POP) (SELECTFONT D 0) (SETCHAR C h) ) ) The character information is also in the tfm companion and that is what T E X uses. The virtual information kicks in when the backend is creating the page stream and embedding the fonts. A.3 The map file In a map file each line maps a font name onto a file that contains the font shapes in bitmap or outline format. For instance in the file lm-texnansi.map we find the line: texnansi-lmr10 LMRoman10-Regular "enclmtexnansi ReEncodeFont"
inclusion when possible, thereby making the file as small as possible. You better make sure that the names are unique for a specific font. In addition to this, there can be directives for extending the font (horizontal stretch) and transforming it into a slanted variant. Both are to be used with care. In MkIV map files are only used for virtual math fonts and just as in MkII we load such files selectively. Users don’t have to worry about this. A.4 The enc file For historic reasons, an encoding file is a blob of PostScript, probably because it can be copied into the final output directly. Given that T E X got extended anyway, you can wonder why this information never ended up in an extended tfm or vf file. It had definitely made the traditional process much more robust. /enclmtexnansi[ /.notdef /Euro ... /dotaccent /hungarumlaut /ogonek ... /ffi /ffl /dotlessi /dotlessj /grave ... /thorn /ydieresis ] def There are excactly 256 entries in such a vector and the names should match those in a pfb file. A.5 The afm file Here we show an excerpt from an afm file that comes with Latin Modern Roman. Just as with a tfm file we start with some general information. However we don’t need to convert the file as is it already in human readable format.
