capPaletteAuto macro (vfw.h)
The capPaletteAuto macro requests that the capture driver sample video frames and automatically create a new palette. You can use this macro or explicitly call the WM_CAP_PAL_AUTOCREATE message.
Syntax
void capPaletteAuto(
hwnd,
iFrames,
iColors
);
Parameters
hwnd
Handle to a capture window.
iFrames
Number of frames to sample.
iColors
Number of colors in the palette. The maximum value for this parameter is 256.
Return value
None
Remarks
The sampled video sequence should include all the colors you want in the palette. To obtain the best palette, you might have to sample the whole sequence rather than a portion of it.
