Perhaps I'm misunderstanding this but for these fonts, which are fixed size, I assume the
height will be 0. correct? as in
GrCreateFont(FONTNAME, 0, NULL);
I'm getting a segfaule because the GdCreateFonts returns 0 at :
/* check builtin fonts first for speed*/
if (!height && (fontclass == MWLF_CLASS_ANY || fontclass == MWLF_CLASS_BUILTIN)) {
for(i = 0; i < scrinfo.fonts; ++i) {
if(!strcmpi(pf[i].name, fontname)) {
pf[i].fontsize = pf[i].cfont->height;
pf[i].fontattr = fontattr;
EPRINTF("1 createfont: (height == 0) found builtin font %s (%d)\n", fontname, i);
return (PMWFONT)&pf[i];
}
}
/*
* Specified height=0 and no builtin font matched name.
* if not font found with other renderer, no font
* will be loaded, and 0 returned.
*
* We used to return the first builtin font. If a font
* return needs to be guaranteed, specify a non-zero
* height, and the closest builtin font to the specified
* height will always be returned.
*/
}
Any size I use returns "not found". Am I using this correctly?
Thanks.
