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).
