1. cnf typically is located either in directory texmf web2c or texmf local web2c The path to file texmf cnf can also be set up by the environment variable TEXMFCNF Next you might need to edit texmf cnf so that pdfTEX can find all necessary files but the texmf cnf files coming with the major TeX distributions should already be set up for normal use You might check into the file texmf cnf to see where the various bits and pieces are going pdf TEX uses the search path variables shown in table 1 TEXMF OUTPUT Normally pdf TEX puts its output files in the current directory If any output file cannot be opened there it tries to open it in the directory specified in the environment variable TEXMFOUTPUT There is no default value for that variable For example if you type pdfetex paper and the current directory is not writable if TEXMFOUTPUT has the value tmp pdfTEX attempts to create tmp paper log and tmp paper pdf if any output is produced TEXINPUTS This variable specifies where pdfTEX finds its input files Image files are considered input files and searched for along this path TEXFORMATS Search path for format fmt files TEXPOOL Search path for pool pool files ENCFONTS Search path for encoding enc files content The pdfTEX user manual used for texmf cnf output files input files images format files text pool files encoding files font map files tfm files virtual fonts TEXMFOUTP
2. explanations follow It is mandatory that fmname is the first field If a basename is given it must be the second field Similarly if fontflags is given it must be the third field if basename is present or the second field if basename is left out It is possible to mix the positions of special encodingfile and fontfile however the first three fields must be given in fixed order timname sets the name of the tfm file for a font the name TEX sees This name must always be given basename sets the base PostScript font name The basename field is checked against the BaseName entry of fonts coming with embedded pdf files If there is a match the font will be removed from the embedded file and a local font is opened which will contain the glyphs from the embedded file This collecting mechanism helps keeping the resulting pdf file size small if many files with similar fonts are to be embedded Therefore it is recommended always to set the basename field If a basename field is given also a fontfile field must be there unless the basename matches one of the 14 standard font names then the fontfile field is optional If the fontfile name is given this font will be embedded depending on flags see below If the fontfile name for a standard font is missing the font will be quietly left out which is fine as pdf viewers will later render the text with their own versions of the font fontflags specify some characteristics of the font T
3. When no step is specified 0 5 steps are used content The pdfTEX user manual Roughly spoken the trick is as follows Consider a text typeset in triple column mode When TeX cannot break a line in the appropriate way the unbreakable parts of the word will stick into the margin When pdfTEX notes this it will try to scale shrink the glyphs in that line using fixed steps until the line fits When lines are too spacy the opposite happens pdfTEX starts scaling stretching the glyphs until the white space gaps is acceptable This glyph stretching and shrinking is called font expansion The additional expanded fonts get artificial names by adding the font expansion value to the base font name e g somefile 10 for 1 stretch or somefile 15 for 1 5 shrink If the autoexpand option is not given tfm files with these names and appropriate dimensions must be available So each expanded variant of a font must have its own tfm file Expanded tfm names like somefile 10 must not be mentioned in the map file but the tfm name of the base font without expansion must be there When no tfm file can be found pdfTEX will try to generate it by executing the scriptmktextfm where available and supported The font expansion is greatly simplified if the autoexpand option is there Then no expanded tfm file versions are needed instead pdfTEX generates expanded copies of the unexpanded tfm data structures and keeps them in its memory pdfTEX requires on
