Block Transfer
Clipped Line Draw
This function OR’s source data (startx, starty) of size (sizex, sizey) with destination data (endx,
endy) and writes it to the destination memory area. sizex, sizey, startx, starty, endx, endy should
be in pixel units.
This function draws a thick (2 pixels wide) patterned (pixel ON,OFF, ON, OFF…) black line from
start point (startx, starty) to end point (endx, endy). Only the pixels that fall on or within the clip
rectangle boundary are drawn. startx, starty, endx, endy should be in pixel units.
