2159 / it works well. the AFM file is only read in if the
2160 / font is changed. this may be chached in the future.
2161 / calls to GetTextExtent with the font unchanged are rather
2162 / efficient!!!
2163 /
2164 / for each font and style used there is an AFM file necessary.
2165 / currently i have only files for the roman font family.
2166 / I try to get files for the other ones!
2167 /
2168 / CAVE: the size of the string is currently always calculated
2169 / in 'points' (1/72 of an inch). this should later on be
2170 / changed to depend on the mapping mode.
2171 / CAVE: the path to the AFM files must be set before calling this
2172 / function. this is usually done by a call like the following:
2173 / wxSetAFMPath("d:\\wxw161\\afm\\");
2174 /
2175 / example:
2176 /
2177 / wxPostScriptDC dc(NULL, true);
2178 / if (dc.Ok()){
2179 / wxSetAFMPath("d:\\wxw161\\afm\\");
2180 / dc.StartDoc("Test");
2181 / dc.StartPage();
2182 / wxCoord w,h;
2183 / dc.SetFont(new wxFont(10, wxROMAN, wxNORMAL, wxNORMAL));
2184 / dc.GetTextExtent("Hallo",&w,&h);
2185 / dc.EndPage();
2186 / dc.EndDoc();
