Remarks

This method supports only 1 bpp indexed (Format1bppIndexed) images.

It is suggested that for noisy images a call to FxBitonalDepeckle() or FxBitonalDespeckleMore() is made before the use of this method to yield better results and so that noise is not outlined.

This method is used in the "Image Processing" Demo.

This method requires the Image Documents component to run.
