.TH gl_setwritemode 3 "22 Feb 1998" "Svgalib (>= 1.2.11)" "Svgalib User Manual"
.SH NAME
gl_setwritemode \- set the font writemode flags
.SH SYNOPSIS
.B #include <vgagl.h>
.BI "void gl_setwritemode(int " m );
.SH DESCRIPTION
Sets the writemode flags for the font routines. It must be the sum of exactly
one choice out of the following two groups:
.PD 0
.TP
.B WRITEMODE_MASKED
.TP
.BR WRITEMODE_OVERWRITE " (default)"
.PD
If
.B WRITEMODE_MASKED
is set, only foreground pixels of the font
are used for write operations; the screen background is not
erased.
.PD 0
.TP
.B FONT_COMPRESSED
.TP
.BR FONT_EXPANDED " (default)"
.PD
If
.B FONT_COMPRESSED
is set, text writes will use the compressed
bit-per-pixel font rather than the expanded font (which would be slightly faster).
