bit_orbit_orBitOrBitOr (Operator)

Name

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

Signature

Description

The operator bit_orbit_orBitOrBitOrBitOr 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

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

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);

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

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

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_orBitOrBitOrBitOr 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.
