gl_setwritemode(3)            Svgalib User Manual           gl_setwritemode(3)

NAME
       gl_setwritemode - set the font writemode flags

SYNOPSIS
       #include <vgagl.h>

       void gl_setwritemode(int m);

DESCRIPTION
       Sets the writemode flags for the font routines. It must be the sum of
       exactly one choice out of the following two groups:

       WRITEMODE_MASKED
       WRITEMODE_OVERWRITE (default)
              If WRITEMODE_MASKED is set, only foreground pixels of the font
              are used for write operations; the screen background is not
              erased.

       FONT_COMPRESSED
       FONT_EXPANDED (default)
              If FONT_COMPRESSED is set, text writes will use the compressed
              bit-per-pixel font rather than the expanded font (which would be
              slightly faster).
