bit_rshiftbit_rshiftbit_rshiftBitRshiftBitRshift (Operator)

Name

bit_rshiftbit_rshiftbit_rshiftBitRshiftBitRshift — Right shift of all pixels of the image.

Signature

bit_rshift(Image : ImageRShift : Shift : )

The operator bit_rshiftbit_rshiftbit_rshiftBitRshiftBitRshift 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.

Parallelization

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.
Automatically parallelized on channel level.
Automatically parallelized on domain level.

Parameters

ImageImageImageImageimage (input_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)

Input image(s).

Result image(s) by shift operation.

shift value

Default value: 3

Suggested values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 24, 30, 31

Typical range of values: 0 ≤ Shift Shift Shift Shift shift ≤ 31

Minimum increment: 1

Recommended increment: 1

Restriction: (Shift >= 1) && (Shift <= 31)

Example (C)

bit_rshift(Int2Image,&ReducedInt2Image,8);
convert_image_type(ReducedInt2Image,&ByteImage,"byte");

Result

If the images are correct (type) and ShiftShiftShiftShiftshift has a valid value the operator bit_rshiftbit_rshiftbit_rshiftBitRshiftBitRshift returns the value 2 (H_MSG_TRUE). The behavior in case of empty input (no input images available) is set via the operator set_system(::'no_object_result',<Result>:)set_system("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.
