High Res Image Capture

[boogieoompa]

Currently I am writing a program which basically takes a signature on a form. The form (a gui with multiple controls) has multiple options all of which are presented on the screen and once the user signs the document it is saved as a .tif. The problem I have is using a 1024x768 screen (pretty much the max res I can get from most screens) the signature looks a little pixely (if thats a word). I dont mind doubling the gui size for a second to take a capture but currently the only UDFs I can find (_ScreenCapture_CaptureWnd etc...) are only taking screen captures not gui captures.

Any suggestions?

Thanks
