If you use the PFD_DRAW_TO_BITMAP pixel format descriptor flag instead of PFD_DRAW_TO_WINDOW, OpenGL will render the image on a bitmap instead of rendering it to a window. After OpenGL has rendered on the bitmap, you can use GDI commands to do whatever you want with the bitmap, from simply blting it on the screen to writing text on the bitmap.

Mar 17, 2019 · PFD_SUPPORT_GENERIC_FORMAT When the image is drawn it is drawn to the window instead of the bitmap. It would be greatly appreciated if anyone can tell me why OpenGL is drawing to the window instead of the bitmap. Deiussum March 17, 2019, 11:47am #2 I’m probably just asking the obvious,...

You can in principle render to a bitmap by using the PFD_DRAW_TO_BITMAP flag instead of PFD_DRAW_TO_WINDOW in the PIXELFORMATDESCRIPTOR. However, doing so will disable all hardware accelearated rendering. This will fall back to Microsofts default OpenGL 1.1 implementation.

Mar 17, 2019 · Hi all, i’m trying to use the other option in PIXELFORMATDESCRIPTOR i.e PFD_DRAW_TO_BITMAP. i want that my code should render into the DIB created by me so that i can save it as a .bmp file or display it on screen using GDI or i can pass that DIB buffer to some other applications so that they can do the rest of the display part.

Example. Full example code included at the end. Windows components for OpenGL. WGL. WGL (can be pronounced wiggle) stands for "Windows-GL", as in "an interface between Windows and OpenGL" - a set of functions from the Windows API to communicate with OpenGL.WGL functions have a wgl prefix and its tokens have a WGL_ prefix.. Default OpenGL version supported on Microsoft systems is 1.1.

Apr 09, 2005 · I want to test out how slow drawing to a bitmap and blitting will be using PFD_DRAW_TO_BITMAP instead of PFD_DOUBLEBUFFER but I'm having trouble when the window needs resized. When I try to resize I always get an unknown exception. It has something to do with copying the context because when I don't do It everything works fine UNTIL I resize. Here is some …

The buffer supports GDI drawing. This flag and PFD_DOUBLEBUFFER are mutually exclusive in the current generic implementation. PFD_SUPPORT_OPENGL: The buffer supports OpenGL drawing. PFD_GENERIC_ACCELERATED: The pixel format is supported by a device driver that accelerates the generic implementation. If this flag is clear and the PFD_GENERIC_FORMAT flag is set, the pixel format is supported …
