Controlling Color
Video digitizer components support color digitization. Therefore, these components provide several functions that allow applications to control the color digitization process.
You can use VDSetInputColorSpaceMode in your application to enable and disable color digitization; you can use the VDGetInputColorSpaceMode function to determine whether color digitization is enabled. The VDUseThisCLUT function allows you to specify a color lookup table to be used by the video digitizer component. In cases where the component cannot accommodate a particular lookup table, your application can use the VDGetCLUTInUse function to retrieve the color lookup table used by the digitizer component.
Your application can determine whether a digitizer component supports color digitization by examining the input capability flags of the component. Specifically, if the digiInDoesColor flag is set to 1, the component supports color digitization. Applications can use the VDGetCurrentFlags function to obtain the input capability flags of a component (see "Getting Information About Video Digitizer Components" on page 8-24 for more information).
Your application can determine a digitizer's supported pixel depths by calling the VDGetDMADepths function.
