Hi,
I have problem with RectTracker. I used RectTracker with ALIGN_NULL for user-specific begin of drawing rect. I want to mark part of drawn image. MaxRect is good for limit to bottom and to right, but top and left coordinates aren't limited.

So in view with borders (0,0,10,10) i can't get rect (5,5,20,20) but only (5,5,10,10) - I expected it and want it Smile

But I can get (-10,-10,5,5) - if (5,5) is origin - and I don't want this Sad

.

Am I wrong or there is error?
Thanks

I naturaly can check and handle it, but I think that there must be better way Cool

void LeftDown(Point p, dword keyflags){
	// Vyrez z obrazku
	RectTracker tr(*this);
	Size sz = GetSize();
tr.Dashed().Animation(40).MaxRect(RectC(0,0,GetSize().cx,GetSize().cy));
	vyrez=RectC(p.x,p.y,0,0);
	vyrez=tr.Track(vyrez,ALIGN_NULL,ALIGN_NULL);
	Refresh();	
};

Edit:
I made modified copy of RectTracker class, that correspond to my need now. But I think that this class (RectTracker) schould be modified or there can be made a new class for clearly defined pixel based operations. Maybe someday I try it. Now I'm beginner only Smile
