Hi opensg users,
i am working to a cluster/server application.
I would like to take screenshots of what is being rendered
On the remote windows,
so I attached to the viewport a GrabForegroundPtr.
The problem is that when I try to save the grabbed image,
it is empty.
fgndImage->setActive(true);
m_pMgr->redraw(); // render pass
fgndImage->setActive(false);
// get foreground image
beginEditCP(fgndImage, GrabForeground::ImageFieldMask);
ImagePtr img = fgndImage->getImage();
endEditCP(fgndImage, GrabForeground::ImageFieldMask);
//get pixel data
beginEditCP(fgndImage, Image::PixelFieldMask);
UInt8 *imageData = img->getData();
int width = img->getWidth();
int height = img->getHeight();
endEditCP(fgndImage, Image::PixelFieldMask);
Does anyone has any clue?
Thanks
E.
