.TH gl_putboxmask 3 "2 Aug 1997" "Svgalib (>= 1.2.11)" "Svgalib User Manual"
|
||
|
|
.SH NAME
|
||
|
|
gl_putboxmask \- copy a masked pixmap to a rectangular area
|
||
|
|
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B #include <vgagl.h>
|
||
|
|
|
||
|
|
.BI "void gl_putboxmask(int " x ", int " y ", int " w ", int " h ", void *" dp );
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Copy the contents of a memory buffer
|
||
|
|
.I dp
|
||
|
|
to a rectangular bitmap at position
|
||
|
|
.RI ( x ", " y )
|
||
|
|
with size
|
||
|
|
.RI ( w ", " h ).
|
||
|
|
|
||
|
|
This function works like
|
||
|
|
.BR gl_putbox ,
|
||
|
|
but does not write pixmap pixels of color zero. If the same pixmap is used often
|
||
|
|
you should consider using the faster
|
||
|
|
.BR gl_putboxmaskcompiled (3).
|
||
|
|
|
||
|
|
Pixmaps are in row-major order. The source pixmap memory has the size
|
||
|
|
.IR w " * " h " * "
|
||
|
|
.BR BYTESPERPIXEL .
