# Setting the Font Path

The parameter -TEXPK: specifies the paths of the fonts used by dviout. In addition, when -TEXROOT: is used, the description in -TEXPK: can be shortened. In a certain situation, specifying the -L: would be necessary.
1. Select "Option -> Setup Parameters -> [Font]" (see [Help]).
2. Set -TEXPK:. If you have several font paths which include the partially common path, you can use the -TEXROOT: parameter. The common part in -TEXPK: can be written with ^r .
See "Examples of TEXPK Settings".
Remarks: If you press the [Guess] button, the dviout will guess and search for the font file. Then, the settings of -TEXROOT:, -TEXPK:, and -L: (and -F: depending in some cases) described in 2 above are set automatically.
If you are asked the question displayed, carefully answer "Yes" or "No".
This font path guessing function would be failed if the resolution is not specified correctly nor the basic fonts are not installed. This function works only for the European language PK font file, the Japanese jxl4font, the Japanese font metric jfm file, and the GTH Font Library.
3.Font Check: Use "[Check] " to check whether the font path setting is correct.
4. Press [Save] to register to Registry that will be referred in the next session of dviout (cf. Q_S1).
5. Press [Apply] to apply the new font path settings to the current dviout session.
