gen_image_proto — Create an image with a specified constant gray value.
gen_image_proto(Image : ImageCleared : Grayval : )
gen_image_proto creates an output image
ImageCleared with the constant gray value Grayval.
If the input image is of type direction, gray values in result
image that are not in the value range that is valid for direction
images are set to the value 255 to mark them as invalid.
ImageCleared has the same dimensions and pixel type as the
input image Image.
Image (input_object) singlechannelimage → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real / complex / vector_field)
Input image.
ImageCleared (output_object) image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real / complex / vector_field)
Image with constant gray value.
Grayval (input_control) number → (real / integer)
Gray value to be used for the output image.
Default: 0
