I would like to take the displayed window bits and transfer this to another
buffer in rgb format. I take the rgb buffer and redraw it in an opengl or
directx application: in this case opengl. Basically, its an overlay-type
function.
I subclassed DoubleBufferWindow and in my own draw function I call readimage().
The bits do change as the window is moved but it doesn't look like the window
when displayed. I've tested the drawing code so I know it works for RGB data.
The readimage() data format looks correct.
The code is pretty trivial but obviously flaw since it doesn't do what I want.
:)
draw()
{
DoubleBufferWindow::draw();
fltk::Rectangle r(x(), y(), w(), h());
fltk::readimage(imagePtr, fltk::RGB, r);
}
I'm using version 2.0 rev 5527. Anyone have ideas as to why the image doesn't
contain the correct contents?
Thanks,
Bruce
