Manual Reference Pages - VGA_COPYTOPLANE (3)
vga_copytoplane - copy linear pixmap to some planes of VGA 16 color mode video memory
void vga_copytoplane(unsigned char *virtual, int pitch, int voffset, int
vpitch, int w, int h, int plane);
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.
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).
