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).
