I'm trying out an idea I had which requires me to capture the contents of a java window/Frame, much like a screenshot but without the window and menubar, just the contents rendered in java, i.e. an exact image of what is visible in the java application at the moment.
I would also like the screenshot to be software rendered, I don't know if I'm using the correct term, but the captured image should not be different on others systems/computers.
Can i for example hijack a render buffer/display buffer or something and write that to in image?
Does anyone have any ideas?
