I started programming on the Mac last week using LSC and am pulling my hair
out trying to get this Picture thing to work. I want to define a small picture
(using the OpenPicture and ClosePicture QuikDraw commands) and repeat it many
times. The problem? I never get any graphics on the screen. I am using
TranSkel and working from the MultiSkel demo (MultiZoom.c) that was archived
with it. Below is the section of code where I am trying to define/draw the
picture. I would be ever so thankful for any insights that you may be able to
give me and maybe I'll even have some hair left on my head.

static Update (resized)
Boolean	resized;
{
Integer	i;
Rect	picSize, dstRect;
PicHandle	picH;	

	EraseRect (&sysWind->portRect);		/* erase window */
	DrawGrowBox(sysWind);	
	SetWindClip (sysWind);		/* set clipRgn to portRect - growbox */
	SetRect(&picSize, 0, 0, 120,100);	
	picH = OpenPicture(&picSize);	/* start "recording" picture */
	MoveTo(0,0);	
	Line(10,10);
	/* misc quikdraw command */
	ClosePicture();			/* stop "recording" */
	SetRect(&dstRect, 20, 20, 140,120);	
	DrawPicture(&picH, &dstRect);	
	ResetWindClip (sysWind);	/* restore old clipRgn */
}

Thanks for any comment or suggestions (like "pull your head out, lamo!")
