ChoosePixelFormat
ChoosePixelFormat is a function in the Win32 Graphics Device Interface (GDI) that selects an appropriate pixel format for a device context (HDC). It searches the pixel format descriptor table associated with the HDC for a format that best matches the attributes specified in a PIXELFORMATDESCRIPTOR structure passed by the caller. The function returns an integer that represents the index of the matching pixel format. If no match is found, the returned value is zero.
int ChoosePixelFormat(HDC hdc, const PIXELFORMATDESCRIPTOR *ppfd);
The PIXELFORMATDESCRIPTOR structure contains fields such as nSize, nVersion, flags (PFD_SUPPORT_OPENGL, PFD_DRAW_TO_WINDOW, etc.), pixel type (PFD_TYPE_RGBA),
Typical usage occurs immediately after creating an OpenGL context but before calling SetPixelFormat, as shown in
Although ChoosePixelFormat aids quick selection of a pixel format, it may not always return the best configuration
