Extended window capturing

[Quinch]

I'm thinking about writing a screencap program that would capture not only the contents of a window but also, if the window stretches past the screen, to capture that too so I can have captures of large pages without having to glue them together by hand. The concept is simple enough - determine the dimensions and position of the window, store each individual pixel, send a page down command, compare pixels to see where the contents of the next page start, repeat. Problem is, is there any way to finally dump that pixel data into an actual image format?

Well, most of the stuff in that thread is a little out of my league for now - I think the only thing I wan to know is if there's a function available that can generate a bitmap from provided data?
