NAME

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

SYNOPSIS

       #include <vga.h>

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

DESCRIPTION

       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).
