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
VDSetInputColorSpaceModein your application to enable and disable color digitization; you can use theVDGetInputColorSpaceModefunction to determine whether color digitization is enabled. TheVDUseThisCLUTfunction 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 theVDGetCLUTInUsefunction 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
digiInDoesColorflag is set to 1, the component supports color digitization. Applications can use theVDGetCurrentFlagsfunction 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
VDGetDMADepthsfunction.
