The user opens a new document from menu->new, the size dialog pops up, user selects a 320x200 pxls view and then PASTEs a captured image data of some window by either the print screen key or a CTRL+C keys from any other graphic app.

At this point, when the user PASTEs the image into my apps view as above mentioned with size 320x200, the image could be bigger than the rect area of my view! So I'd have to resize to fit the image! Right!

Suppose the image will be of size 380x380 pxls, then I would resize to fit it, but I do not want the remaining of the view (the white area) to show while the view is fully maximized, as well not to effect the size of the bitmap at all!

Something like whta the "MGI PhotoSuite SE" app does already!
