TRSGPImageAttributes.ColorChannels[TRSGPColorAdjustType] Property

Delphi

public
  property ColorChannels[Index: TRSGPColorAdjustType]: TRSGPColorChannelFlag read GetColorChannels write SetColorChannels;
 

You can use the ColorChannels property to convert an image to a cyan-magenta-yellow-black (CMYK) color space and examine the intensities of one of the CMYK color channels. For example, suppose you create an Image Attributes object and set its bitmap output channel to ccfC (cyna). If you pass the Image Attributes object to the DrawImage method, the cyan component of each pixel is calculated, and each pixel in the rendered image is a shade of gray that indicates the intensity of its cyan channel. Similarly, you can render images that indicate the intensities of the magenta, yellow, and black channels.
