If the [Guess] button is pressed on the [Font] property sheet, dviout will guess -TEXROOT: and -TEXPK: and set the parameter in the Property Sheet automatically. However, this is only a guessing, so you might have to correct the setting in some case.
By pressing the [OK], [Apply], and [Save] buttons, the guessed parameter settings can be applied.
Dviout can guess the location of only European language PK fonts, Japanese jx14 fonts, Japanese jfm files, and GTH Font Library. If the font does not exist, guessing is not possible. Network drives are ignored.
The resolution (cf. -dpi:) must be correctly specified.
If dviout find the searched font in more than on one directory, dviout will ask you which one you want to use.
For details, refer to "[Guess] Specifications".
The defaut vaules can be set to TEXROOT/TEXPK also by the [Guess] button.
