WM_CAP_PAL_MANUALCREATE
The WM_CAP_PAL_MANUALCREATE message requests that the capture driver manually
sample video frames and create a new palette. You can send this message
explicitly or by using the capPaletteManual macro.
WM_CAP_PAL_MANUALCREATE
wParam = (WPARAM) (fGrab);
lParam = (LPARAM) (DWORD) (iColors);
Parameters
fGrab
Palette histogram flag. Set this parameter to TRUE for each frame included in
creating the optimal palette. After the last frame has been collected, set this
parameter to FALSE to calculate the optimal palette and send it to the capture
driver.
iColors
Number of colors in the palette. The maximum value for this parameter is 256.
This value is used only during collection of the first frame in a sequence.
Return Values
Returns TRUE if successful or FALSE otherwise.
If an error occurs and an error callback function is set using the
WM_CAP_SET_CALLBACK_ERROR message, the error callback function is called.
