VisIt crashes down in VTK saving an image with more that 0.5 Gbytes of pixels.

[brugger1]

When you try and save an image that contains more than 0.5Gbytes of pixels, VTK crashes reading back the pixels from Mesa. Right now VisIt has logic that prevents the user from doing this, so that logic will need to be disabled to replicate the crash.

Can you put a link here to the logic that would need to be removed?

The logic to remove is in ViewerWindowManager::SaveWindow.

        // if the total image size is too large, reduce them
        // proportionally.
        if (w * h > 536756224)
            {
                double image_size = (double)(w * h);
                w = (int)((double)w * std::sqrt(536756224. / image_size));
                h = (int)((double)h * std::sqrt(536756224. / image_size));
                GetViewerMessaging()->Message(
                    TR("The window was too large to save at the requested resolution.  "
                       "The resolution has been automatically reduced."));
            }
