Need speedy graphics help

[schwarts@cps.msu.edu (Steven Eric Schwartz)]

I need a quick procedure to out put an array of ints from 0-15 (ie. colors)
to a graphics window. Below is one I thought would work:
 
void printpic(void)
{
    int i,j;
    Rect r1;
 
    GetPortRect(&r1);
    SetPenSize(2,1);
    for (j = 0; j < HEIGHT; j++) {
      for (i = 0; i < WIDTH ; i++) {
        SetDithColor((ColorsDith) col[i][j]);
        MoveTo(2*i,j);
        Line(2,1);
      }
    }
}
 
I tried this when I had a graphics window open in ORCA/C 2.0 but it didn't
work. SetDithColor() fills a pen with a pattern for color 0 through 15. Can
anyone give me some speedy help?
