crop window region and save as image (win32)

[User 9123917]

Let's say I have a window created and I'm interested on certain region in that window (say rect(10,10,300,300)) and want to somehow crop it and save as an image file. May I know how can I do this?

You can copy part of the Window to a new device context using the BitBlt function[^]. This article[^] shows how to save it to a file.

Use the best guess
