gray_range_rectgray_range_rectGrayRangeRectgray_range_rectGrayRangeRectGrayRangeRect calculates the gray value range, i.e., the difference (max - min) of the maximum and minimum gray values, of the input image ImageImageImageImageImageimage within a rectangular mask of size (MaskHeightMaskHeightMaskHeightMaskHeightMaskHeightmaskHeight, MaskWidthMaskWidthMaskWidthMaskWidthMaskWidthmaskWidth) for each image point. The resulting image is returned in ImageResultImageResultImageResultImageResultImageResultimageResult. If the parameters MaskHeightMaskHeightMaskHeightMaskHeightMaskHeightmaskHeight or MaskWidthMaskWidthMaskWidthMaskWidthMaskWidthmaskWidth are even, they are changed to the next smaller odd value. At the border of the image the gray values are mirrored.

gray_range_rectgray_range_rectGrayRangeRectgray_range_rectGrayRangeRectGrayRangeRect returns 2 (H_MSG_TRUE) if all parameters are correct. If the input is empty the behavior can be set via set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
