ImageRedact Method

Redact rectangular part of the image

Redacts a part of the image specified by a rectangle, by changing the content of the image. This is not an annotation, the image data is changed and there will be no way to get the original data from the image itself. The content is changed by setting all pixels to the same color. This color, in general, is black, but that depends on the color space of the image.
