SYNOPSIS

10       #include <vgagl.h>

12       void gl_setwritemode(int m);

DESCRIPTION

16       Sets  the  writemode flags for the font routines. It must be the sum of
17       exactly one choice out of the following two groups:
18
19       WRITEMODE_MASKED
20       WRITEMODE_OVERWRITE (default)
21              If WRITEMODE_MASKED is set, only foreground pixels of  the  font
22              are  used  for  write  operations;  the screen background is not
23              erased.
24
25
26       FONT_COMPRESSED
27       FONT_EXPANDED (default)
28              If FONT_COMPRESSED is set, text writes will use  the  compressed
29              bit-per-pixel font rather than the expanded font (which would be
30              slightly faster).
