I used ChPaint to paint the image. It works ok when using it diretly in Paint method, but using it through the Painter rasterizer it gives different (wrong) results.
PS: It looks like Painter's DrawImage instead of drawing part of image (like in this line - we should see only a top left img's rectangle of size cx and cy)
w.DrawImage(0, 0, cx, cy, img, RectC(0, 0, cx, cy));
it scales down the whole image to a cx and cy size.
Here's the screenshot and the test case:

Ah, stupid leftovers... Looks I will have to develop the correct clipping there...
