Remarks

  • This operation can also be used to invert the color of a 1-bit image, making the black white and the white black.
  • This operation supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
  • This command supports signed data images.

This command changes the image data. If the image has a LUT, the command will work on the LUT not the image data.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
