Hi Eduardo,
I don't know much about XCB, but I recently implemented glyph drawing as
part of libfreerdpgdi. Unfortunately, if you're porting xfreerdp, you don't
get to benefit from libfreerdpgdi. I've been doing it a little bit
differently for the purpose of simplicity. Take a look at gdi_glyph_convert
here:
http://freerdp.git.sourceforge.net/git/gitweb.cgi?p=freerdp/freerdp.git;a=blob;f=libfreerdpgdi/gdi_color.c;h=4b987be0a3b7152d069743a1816a80b6f9484527;hb=refs/heads/libfreerdpgdi
<http://freerdp.git.sourceforge.net/git/gitweb.cgi?p=freerdp/freerdp.git;a=blob;f=libfreerdpgdi/gdi_color.c;h=4b987be0a3b7152d069743a1816a80b6f9484527;hb=refs/heads/libfreerdpgdi>glyphs
are received in 1-bit-per-pixel format, which is a bit harder to use when
you want to do blitting operations. For libfreerdpgdi, I'm converting the
glyphs to 1-byte-per-pixel format, so that I don't need to continuously
extract the needed bits when blitting glyphs. A bit set to '1' is white, and
a bit set to '0' is black. If you want to blit '1' with a 16bpp pixel, you
need to convert '1' to 16bpp, such that you get 0xFFFF for your glyph pixel.
If the glyph pixel is '0', you'd get 0x0000.
