[QUOTE="gemx, post: 560843, member: 26324"] I already thought about something like "GetCurrentImage(Rectangle source,Rectangle target)" which would work but the problem with this is that you have to specify the dimensions when in OnFrame(...) which would result in every application that uses the GetCurrentImage(...) would get the same regions or worse different Rect request would be overriden by each other. So the only solution i found was to deliver the source surface untouched in the event handler so that every function that registered to it can make it's own resizing but that would on the other hand mean the might happen several resizes (copies from GPU -> CPU) for the same surface which is also bad. Best intermediate solution would be to always resize the image to something like 300*200 (keeping the AR) and then output it via GetCurrentImage. How about that? [/QUOTE]
