bit_orbit_orBitOrBitOrbit_or (Operator)

bit_orbit_orBitOrBitOrbit_or — Bit-by-bit OR of all pixels of the input images.

Signature

bit_or(Image1, Image2 : ImageOr : : )

Herror bit_or(const Hobject Image1, const Hobject Image2, Hobject* ImageOr)

Herror T_bit_or(const Hobject Image1, const Hobject Image2, Hobject* ImageOr)

void BitOr(const HObject& Image1, const HObject& Image2, HObject* ImageOr)

HImage HImage::BitOr(const HImage& Image2) const

static void HOperatorSet.BitOr(HObject image1, HObject image2, out HObject imageOr)

HImage HImage.BitOr(HImage image2)

def bit_or(image_1: HObject, image_2: HObject) -> HObject

Description

The operator bit_orbit_orBitOrBitOrbit_or calculates the “or” of all pixels of the input images bit by bit. The semantics of the “or”operation corresponds to that of C for the respective types (signed char, unsigned char, short, unsigned short, int/long). The images must have the same size and pixel type. The pixels within the definition range of the image in the first parameter are processed.

Several images can be processed in one call. In this case both input parameters contain the same number of images which are then processed in pairs. An output image is generated for every pair.

Execution Information

• 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

Image1Image1Image1image1image_1 (input_object)  (multichannel-)image(-array) → objectHImageHObjectHObjectHobject (byte / direction / cyclic / int1 / int2 / uint2 / int4)

Input image(s) 1.

Image2Image2Image2image2image_2 (input_object)  (multichannel-)image(-array) → objectHImageHObjectHObjectHobject (byte / direction / cyclic / int1 / int2 / uint2 / int4)

Input image(s) 2.

ImageOrImageOrImageOrimageOrimage_or (output_object)  (multichannel-)image(-array) → objectHImageHObjectHObjectHobject * (byte / direction / cyclic / int1 / int2 / uint2 / int4)

Result image(s) by OR-operation.

Example (HDevelop)

read_image(Image1,'fabrik')
dev_display (Image1)
read_image(Image2,'monkey')
dev_display (Image2)
bit_or(Image1,Image2,ImageBitOr)
dev_display (ImageBitOr)

Example (C)

read_image(&Image1,"monkey");
disp_image(Image1,WindowHandle);
read_image(&Image2,"fabrik");
disp_image(Image2,WindowHandle);
bit_or(Image1,Image2,&ImageBitOr);
disp_image(ImageBitOr,WindowHandle);

Example (HDevelop)

read_image(Image1,'fabrik')
dev_display (Image1)
read_image(Image2,'monkey')
dev_display (Image2)
bit_or(Image1,Image2,ImageBitOr)
dev_display (ImageBitOr)

Example (HDevelop)

read_image(Image1,'fabrik')
dev_display (Image1)
read_image(Image2,'monkey')
dev_display (Image2)
bit_or(Image1,Image2,ImageBitOr)
dev_display (ImageBitOr)

Result

If the images are correct (type and number) the operator bit_orbit_orBitOrBitOrbit_or 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>)set_system("no_object_result",<Result>) If necessary an exception is raised.
