I like how xterm has the ability to use MacOS X system fonts. The
antialiasing can look pretty bad though. It's like the "do not
antialias under this size" preferences are not honored. Antialiased
9-point fonts are impossible to read.
I'm trying to incorporate similar font-loading functionality into a
library I am porting. I tried to look through the X11 source to see how
it's being done, but it feels a little like searching for a needle in a
haystack. To add MacOS X font support via FreeType in X11, do I need to
use FreeType's Mac-specific API? Using something like
FT_GetFont_From_Mac_Name() creates a dependence on CoreFoundation. I
cannot seem to properly load a font with that approach. Does Apple's
X11 do something like this, or is the font support at a lower level?
The current implementation of the library is limiting. FreeType is used
for font loading, but the library only loads fonts by file name from a
specific path. I would like to implement a similar find-font-by-name
method. I tried something like this:
#ifdef __APPLE__
/* Locate fonts by name on MacOS X. */
error = FT_GetFile_From_Mac_Name(fontName, &path, &face_index);
if (! error) {
error = FT_New_Face(library, path.name, 0, &face);
if (error) {
sprintf(stderr, "ERROR: Unable to create face for %s.\n",
path.name);
}
} else {
sprintf(stderr, "ERROR: Unable to get %s font file.\n", fontName);
}
#else
if (! (path = _flSearchFont(fontName)))
return NULL;
error = FT_New_Face(library, path, 0, &face);
free(path);
#endif
No errors are reported, but the font doesn't seem to load. I'm not sure
if the above approach is even the correct one to use from within X11.
Any suggestions?
