Gets the size of a particular resolution.
resolution
Resolution index
A Leadtools.LeadSize value that represents the resolution.
A resolution index equal to zero represents the highest resolution and the NumberOfResolutions represents the lowest resolution. So if the NumberOfResolutions equals 3 and the image size is 200x100, then this function will return 200x100 when the resolution index equals zero, 100x50 when the resolution index equals 1, and 50x25 when the resolution index equals 2.
For an example that enumerates all of the available resolution sizes for the loaded image, refer to JpipRasterImageViewer.
