- // method for calculating string widths in postscript:
- // read in the AFM (adobe font metrics) file for the
- // actual font, parse it and extract the character widths
- // and also the descender. this may be improved, but for now
- // it works well. the AFM file is only read in if the
- // font is changed. this may be chached in the future.
- // calls to GetTextExtent with the font unchanged are rather
- // efficient!!!
- //
- // for each font and style used there is an AFM file necessary.
- // currently i have only files for the roman font family.
- // i try to get files for the other ones!
- //
- // CAVE: the size of the string is currently always calculated
- // in 'points' (1/72 of an inch). this should later on be
- // changed to depend on the mapping mode.
- // CAVE: the path to the AFM files must be set before calling this
- // function. this is usually done by a call like the following:
- // wxSetAFMPath("d:\\wxw161\\afm\\");
- //
- // example:
- //
- // wxPostScriptDC dc(NULL, TRUE);
- // if (dc.Ok()){
- // wxSetAFMPath("d:\\wxw161\\afm\\");
- // dc.StartDoc("Test");
- // dc.StartPage();
- // long w,h;
- // dc.SetFont(new wxFont(10, wxROMAN, wxNORMAL, wxNORMAL));
- // dc.GetTextExtent("Hallo",&w,&h);
