Parameters

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

Return Value

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

This operation removes borders that commonly appear in scanned text documents. Any or all of the four borders can be detected and removed.
This operation works only on 1-bit black and white images.
If a region is selected, only the selected region will be changed by this operation. If no region is selected, the whole image will be processed.
This operation does not support signed data images.
This operation does not support 32-bit grayscale images.
