CImagePalette class

  • Artikkel

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The CImagePalette class manages palettes for video renderers. It can be used to create a logical palette from a video format. This class is intended to be used with the CBaseWindow and CDrawImage classes, so it is somewhat specialized.
