Sure. But it doesn't know what your fonts look like, of course.
1) color
check out the rend_getfg() and rend_getbg() macro in image.h.
AFAIR they return the "internal" representation of the color, where
"0" means the "default" color. Use coli2e() to convert non-zero
values to a real ANSI color, use any color you like for the
"default color" case.
2) font
the font information is basically just the ISO-2022 character
set numbers plus some extensions. 0x00 is always the "default"
font.
size 94:
0x30 (0) Alternate charset
0x42 (B) ASCII
0x49 (I) japanese katakana
...
double with fonts use codes < 32 (i.e. control characters).
0x01 (^A) GB 2312-80
0x02 (^B) JIS X 0208 (1990)
0x03 (^C) KSC 5601-1992
0x0d (^D) JIS X 0212 (1990)
utf-8 mode is completely different. It (mis-)uses the font slot as
place to store the most significant byte. I.e.:
utf8char = image | (font << 8)
Combining characters are recoded to the range 0xd800-0xdfff.
The real string is stored in the "combchars" array.
Cheers,
Michael.
