.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).
