Parameters

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

Return Value

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

This operation has the following features:

It uses the center of the image as the center of rotation.
It can rotate the image clockwise or counterclockwise up to 360 degrees in 100th of a degree increments.
It can resize the image to accommodate the rotated height and width, or it can retain the original height and width, cropping the image as necessary.
It uses Leadtools.Services.ImageProcessing.DataContracts.RotateRequest.FillColor as the background color to fill any new area created by the rotation.

RotateCommandFlags.Resample and RotateCommandFlags.Bicubic can be combined with RotateCommandFlags.Resize, but they can not be combined with each other.

If RotateCommandFlags.Resize is set, then the image is resized. Otherwise, the image is cropped.

Interpolation can be done while rotating certain images. This produces superior output, eliminating the jaggedness occurring when rotating images at angles that are not multiples of 90. (ie when RotateRequest.Angle is not a multiple of 9000).
