VDSetInputColorSpaceMode
The VDSetInputColorSpaceMode function allows applications to choose between color and grayscale digitized video.
pascal VideoDigitizerError VDSetInputColorSpaceMode
(VideoDigitizerComponent ci,
short colorSpaceMode);
ci
- Specifies the video digitizer component for the request. Applications obtain this reference from the Component Manager's
OpenComponent function.
colorSpaceMode
- Controls color digitization. The following values are valid:
0
- Grayscale digitization
1
- Color digitization
DESCRIPTION
Applications can determine whether a digitizer component supports grayscale or color digitization by examining the digitizer component's input capability flags. Specifically, if the digiInDoesColor flag is set to 1, the digitizer component supports color digitization. Similarly, if the digiInDoesBW flag is set to 1, the digitizer component supports grayscale digitization. Applications can use the VDGetCurrentFlags function (described on page 8-25) to obtain the input capability flags of a digitizer component.
