Hi there,
I’m trying to draw a flipped NSImageBitmapRep object (data comes out of an
OpenGL depth buffer) in a NSView. I thought I could set up an appropriate
affine transform (x’ = x, y’ = height - y), embed it in a dictionary and put
that in the hints parameter of a -drawInRect:fromRect:…hin
PS : Of course, a workaround is to flip the view coordinates thus:
[myView translateOriginToPoint:NSMakePoint(0, [self frame].size.height)];
[myView scaleUnitSquareToSize:NSMakeSize(1, -1)];
but it still does not explain why -drawInRect:fromRect:…hints: seems to ignore
the hints.
