Create an image with a specified constant gray value.
gen_image_proto creates an output image ImageCleared with the constant gray value Grayval. ImageCleared has the same dimensions and pixel type as the input image Image.
|
Image (input_object) |
image -> object : byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / dvf |
| Input image. | |
|
ImageCleared (output_object) |
image -> object : byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / dvf |
| Image with constant gray value. | |
|
Grayval (input_control) |
number -> real / integer |
| Gray value to be used for the output image. | |
| Default value: 0 | |
| Suggested values: 0, 1, 2, 5, 10, 16, 32, 64, 128, 253, 254, 255 | |
gen_image_proto returns 2 (H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
gen_image_proto is reentrant and processed without parallelization.
