Remarks

  • For example, suppose you are working with a color image. In the SampleColor property or the sampleColor parameter, set the red value portion of the Color structure to 125, the green portion to 165 and the blue portion to 100. In the TargetColor property or the targetColor parameter you set the red value portion to 170, the green to 120 and the blue to 200. If you set SampleTargetCommandBitmapEffectsFlags.Blue in the Flags property or the flags parameter, then for every pixel in the image that has a blue value of 100, that blue value will be changed to 200, thus shifting the colors in the image. Depending on whether you set SampleTargetCommandBitmapEffectsFlags.Low, SampleTargetCommandBitmapEffectsFlags.Mid, or SampleTargetCommandBitmapEffectsFlags.High, either the shadow values in the blue channel will be remapped, or the midtone values in the blue channel will be remapped, or the highlight values in the blue channel will be remapped.
  • For grayscale images the gray value of the SampleColor and TargetColor properties or the sampleColor and targetColor parameters are used, and the different channel flags have the same effect since it works on the same channel (gray channel). Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in all LEADTOOLS Document and Medical Imaging toolkits.
  • This command does not support signed data images.
