1699 / font is changed. this may be chached in the future.
1700 / calls to GetTextExtent with the font unchanged are rather
1701 / efficient!!!
1702 /
1703 / for each font and style used there is an AFM file necessary.
1704 / currently i have only files for the roman font family.
1705 / I try to get files for the other ones!
1706 /
1707 / CAVE: the size of the string is currently always calculated
1708 / in 'points' (1/72 of an inch). this should later on be
1709 / changed to depend on the mapping mode.
1710 / CAVE: the path to the AFM files must be set before calling this
1711 / function. this is usually done by a call like the following:
1712 / wxSetAFMPath("d:\\wxw161\\afm\\");
1713 /
1714 / example:
1715 /
1716 / wxPostScriptDC dc(NULL, TRUE);
1717 / if (dc.Ok()){
1718 / wxSetAFMPath("d:\\wxw161\\afm\\");
