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).

AUTHOR
       This manual page	was edited by Michael Weller  <eowmob@exp-math.uni-es-
       sen.de>.	 The  exact  source  of	 the referenced	demo as	well as	of the
       original	documentation is unknown.

       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.
