capPaletteManual
The capPaletteManual
macro requests that the capture driver manually sample video frames and create
a new palette. You can use this macro or explicitly call the WM_CAP_PAL_MANUALCREATE
BOOL capPaletteManual(
hwnd, |
|
fGrab, |
|
iColors |
|
); |

Parameters
hwnd
Handle of a
capture window.
fGrab

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

if successful or FALSE otherwise.

occurs and an error callback function is set using the capSetCallbackOnError
macro, the error callback function is called.
