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).

It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.

Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
