The code to read the font list is already there for the -l/-L switches, so you can just read the list and check that the font is in that list. However, note that the argument to font= can also be an absolute path to a .ttf file, which needn't exist in the fontcap file. This issue affects any module which accepts font names, e.g. d.text. At present, R_font() doesn't return a result. R_font() itself doesn't care whether the font exists; the font isn't actually loaded until you try to draw something with it. [Part of the reason for this is so that, when using direct rendering, modules don't waste time loading the default "romans" font when they aren't going to use it.] Similarly, there's no check that $GRASS_FONT is valid; the value is just passed to R_font(), and validity only becomes an issue when you try to draw text. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
