Subject: CropTransform

Image quality Issue
When I zoom in on an image, crop the image and redisplay the quality is degraded. The images I am working with are grayscale images 8bit.

I changed my code to do use copyrect from the canvas and the problem goes away.

Not a big deal since I have coded around it but thought you should know. It would simplify my code to be able to use the croptransform.

Questin
Also, is there a way to determine the coordinates of the visible portion of an image when zoomed at greater than 100% and the entire image doesn't fit? (Since I am zooming I don't want to resize it to fit, but want to eliminate what isn't showing when performing a crop.)
