Value. Description. D. PFD_DOUBLEBUFFER. The pixel buffer is double-buffered. This flag and PFD_SUPPORT_GDI MUST NOT both be set.. S. PFD_STEREO. The pixel buffer MAY be stereoscopic; that is, it MAY specify a color plane that is used to create the illusion of depth in an image. <48>. W. PFD_DRAW_TO_WINDOW. The pixel buffer can draw to a window or device surface.

The pixel format is supported by the GDI software implementation, which is also known as the generic implementation. If this bit is clear, the pixel format is supported by a device driver or hardware.

I've an 25 years old Fortran app running nicely under Windows 7 and Classic mode and complied and linked under Visual Studio 2010. Now I make a new project under Visual Studio 2015 and it compiles and links nicely under Win32 but during running the follwing happens: All GDI graphics appears as it should All OpenGL call run without any crash and they seem to consume computer time but nothing is ...Author: Botor

Aug 11, 2015 · (PFD_SUPPORT_GDI should not be used with PFD_DOUBLEBUFFER.) Used to be OK with Win7 but some Win10 fails, so now we have to use SINGLE buffer. To analyze the problem I created a simple MFC test program --- I can display OpenGL cubes and GDI lines. I also added GLUT Tessellation since our software is using tessellation as well.

PFD_SUPPORT_GDI means that you can do GDI drawing to the window. This forces a software OpenGL implementation, because you cannot use GDI drawing (which is software) with hardware-based OpenGL drawing. So no, you cannot have both hardware OpenGL (or D3D) acceleration and GDI support …

Aug 10, 2009 · when setting up the pixel format, if I don't set the PFD_SUPPORT_GDI flag in the dwFlags field of the PIXELFORMATDESCRIPTOR, then everything goes well until I call wglMakeCurrent(), where an exception is thrown or the function return 0 (indicating failure) and glGetError() returns GL_INVALID_OPERATION.

Basically, a bitmap is created with CreateDIBSection. A pixel format with the PFD_DRAW_TO_BITMAP, PFD_SUPPORT_OPENGL, PFD_SUPPORT_GDI flags must be chosen. After creating a WGL context and binding it, OpenGL rendering can proceed. これだけでは良く分からないため、以下の記事を参照し …
