bit_rshiftbit_rshiftBitRshiftBitRshift (Operator)

Name

bit_rshiftbit_rshiftBitRshiftBitRshift — Right shift of all pixels of the image.

Signature

bit_rshift(Image : ImageRShift : Shift : )

Herror bit_rshift(const Hobject Image, Hobject* ImageRShift, const Hlong Shift)

Herror T_bit_rshift(const Hobject Image, Hobject* ImageRShift, const Htuple Shift)

void BitRshift(const HObject& Image, HObject* ImageRShift, const HTuple& Shift)

HImage HImage::BitRshift(Hlong Shift) const

static void HOperatorSet.BitRshift(HObject image, out HObject imageRShift, HTuple shift)

HImage HImage.BitRshift(int shift)

Description

The operator bit_rshiftbit_rshiftBitRshiftBitRshiftBitRshift 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.

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_rshiftBitRshiftBitRshiftBitRshift 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>) If necessary an exception is raised.
