Does it work ?

I am using a 70G machine, which was never very fast for pixel operations.

I can not seem to get a patch of pixels to write from

rectwrite(0,XSIZE,0,YSIZE,Image);

The pixels are in an array of shorts.

static Colorindex Image[XSIZE][YSIZE];


I can get the pixels out by doing a

ortho2(-0.5,float(XSIZE)-0.5,-0.5,float(YSIZE-0.5));

for(i=0;i<XSIZE;i++)for(j=0;j<YSIZE;j++)
                {
                color(Image[i][j]);
                pnt2i(i,j);
                }
