vga_copytoplane(3)	      Svgalib User Manual	    vga_copytoplane(3)

       vga_copytoplane	-  copy	 linear	 pixmap	to some	planes of VGA 16 color
       mode video memory

       #include	<vga.h>

       void vga_copytoplane(unsigned char *virtual, int	 pitch,	 int  voffset,
       int vpitch, int w, int h, int plane);

       Similar	to vga_copytoplanar16(3), but copies only a subset of the four
       16-color	mode planes (plane should be in	the range 0 .. 15).  The  bits
       set in plane select which of the	four 16-color mode planes to modify.

       Assumes	pixels stored in consecutive bytes ranging from	0 to 15	in the
       virtual screen.

       Copies part of a	linear virtual screen in system	memory at *virtual  to
       VGA  16	mode  video memory.  pitch is the logical width	of the virtual
       screen (in pixels (which	are one	byte large)), voffset is  the  address
       offset  into  video memory, vpitch is the logical scanline width	of the
       screen.	(w, h) is the size of the area to copy in pixels  (width  must
       be multiple of 4).

       This manual page	was edited by Michael Weller  <eowmob@exp-math.uni-es->.	 The exact source of the referenced function 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 <>.

       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.
