Hi,
I got the things working ok. Had to add the baseline handling and after that
the fonts appeared on the right places. At the moment this is enough for me.
Thanks.

Hello,

I use the following code (not in 0.91 but allready in cvs):
====================== font_truetype2.c ===============
/*
* Offset the starting point if necessary,
* FreeType always aligns at baseline
*/
if (flags & MWTF_BOTTOM) {
pos.y = (abs(size->metrics.descender) + 63) & ~63;
/* descent */
} else if (flags & MWTF_TOP) {
pos.y = (size->metrics.ascender + 63) & ~63;
/* -ascent */
} else {
pos.y = 0;
}
Bye
Uwe
