GLDib Demonstrates Rendering to DIBSections By Using OpenGL |
Q272221
The information in this article applies to:
- Microsoft Win32 Software Development Kit (SDK)
SUMMARY
The GLDib sample, which is contained in the self-extracting executable, Gldib1.exe, demonstrates how to render an OpenGL scene into a DIBSection (a device-independent bitmap). The sample also demonstrates how to display and print the DIBSection, thus effectively rendering OpenGL to the printer.
The sample creates a DIBSection that is in the same format as the screen, which avoids the need for system-translation of the DIB at display time. This can yield relatively fast animation for unaccelerated systems.
The frames-per-second (FPS) animation rate is displayed in the title bar of the window. You can reset this calculation (after resizing the window for instance) by pressing the "R" (or "r") key on your keyboard.
