Capture minimized windows

Hey people

I was wondering, is it possible to capture the image of a window which
is minimised, similar to windows printscreen.

I know it is possible to maximize a window, take printscreen and then
minimize it, but i searched google and couldnt find references to
anyone who is able to take the window image straight out of memory.

I am beginning to think it is not possible at all

If someone knows otherwise, please could you point me in the right
direction.

regards, tom

If you're writing Java programs, you should already know that when a
window isn't visible, it doesn't exist. When it comes back, it has to be
repainted. So it's impossible to capture a minimized window, because the
pixels just aren't there to be captured.

However, you can paint to an offscreen buffer. See

for an example.
