|
|
.SH NAME
|
||
|
|

|
||
|
|
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B #include <vgagl.h>
|
||
|
|
|
||
|
|
.BI "void gl_expandfont(int " fw ", int " fh ", int " c ", void *" sfp ", void *" dfp );
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Convert a bit-per-pixel font at
|
||
|
|
.IR sfp
|
||
|
|
with 256 characters of size
|
||
|
|
.RI ( fw ", " fh )
|
||
|
|
to an expanded font of character pixmaps, stored at
|
||
|
|
.I dfp
|
||
|
|
(size will be 256 *
|
||
|
|
.IR fw " * " fw
|
||
|
|
.RB " * " BYTESPERPIXEL ).
|
||
|
|
All non-zero pixels are set to color
|
||

It is possible to use non expanded fonts (but it is slower) when
|
||
|
|
the
|
||
|
|
.BR "FONT_COMPRESSED gl_setwritemode" (3)
|
||
|
|
flag is set.
