Remarks

  • This operation can process the whole image or a region of the image.
  • The operation can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set the Leadtools.Services.ImageProcessing.DataContracts.MinimumRequest.Dimension property (or the dimension parameter of the Constructor)to 8. Each pixel is replaced with the minimum value of its neighborhood.
  • 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 operation does not support 32-bit grayscale images.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
