bit_maskbit_maskBitMaskbit_maskBitMaskBitMask (Operator)

Name

bit_maskbit_maskBitMaskbit_maskBitMaskBitMask — Logical “AND” of each pixel using a bit mask.

Signature

Description

The operator bit_maskbit_maskBitMaskbit_maskBitMaskBitMask carries out an “and” operation of each pixel with a fixed mask. The semantics of the “and” operation corresponds to that of C for the respective types (signed char, unsigned char, unsigned short, 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

Result

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