Parameters

request: A System.Runtime.Serialization.DataContractAttribute containing the data that will be used in this Halftone operation.

Return Value

A System.Runtime.Serialization.DataContractAttribute containing the modified image resulting from the Halftone operation.

For the Leadtools.Services.ImageProcessing.DataContracts.HalftoneCommandType.UserDefined option, the number of images in the list must be at least equal to (Dimension * Dimension + 1). Images with higher indexes correspond to higher intensity values.
This command can process the whole image or a region of the image.
This command does not support 12 and 16-bit grayscale and 48 and 64-bit color images.
This command does not support signed data images.
This command supports 32-bit grayscale images.
