Video Digitizer Component Functions

Setting Source Characteristics

This section discusses the video digitizer component functions that allow applications to set the spatial characteristics of the source video signal. You can use these functions in your application to set and retrieve information about the maximum source rectangle, the active source rectangle, the vertical blanking rectangle, and the digitizer rectangle. For a complete discussion of the relationship between these rectangles, see "About Video Digitizer Components," which begins on page 8-3.

You can use the VDGetMaxSrcRect function in your application to get the size and location of the maximum source rectangle. Similarly, the VDGetActiveSrcRect function allows you to get this information about the active source rectangle, and the VDGetVBlankRect function enables you to obtain information about the vertical blanking rectangle.

You can use the VDSetDigitizerRect function to set the size and location of the digitizer rectangle. The VDGetDigitizerRect function lets you retrieve the size and location of this rectangle.
