bit_rshift — Right shift of all pixels of the image.
bit_rshift(Image : ImageRShift : Shift : )
该算子 bit_rshift calculates a “right shift”
of all pixels of the input image bit by bit.
The semantics of the “right shift” operation corresponds to that of C
(“>>”) for the
respective types (signed char, unsigned char, short, unsigned short, int/long).
Only the pixels within the definition range of the image
are processed.
Several images can be processed in one call. An output image is generated for every input image.
Image (input_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)
Input image(s).
ImageRShift (output_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)
Result image(s) by shift operation.
Shift (input_control) integer → (integer)

Default: 3
Suggested values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 24, 30, 31
Minimum increment: 1
Recommended increment: 1
bit_rshift(Int2Image,&ReducedInt2Image,8); convert_image_type(ReducedInt2Image,&ByteImage,"byte");
If the images are correct (type) and
Shift has a valid value 该算子 bit_rshift
返回值 2 (
H_MSG_TRUE)
.
The behavior in case of empty input (no input images available) is
set via 该算子
set_system(::'no_object_result',<Result>:)
If necessary an exception is raised.
