Name
bit_slicebit_sliceBitSliceBitSlice — Extract a bit from the pixels.
The operator bit_slicebit_sliceBitSliceBitSliceBitSlice extracts a bit level from the input image.
The semantics of the “and” 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.
- 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.
Result image(s) by extraction.

If the images are correct (type) and
BitBitBitBitbit has a valid value, the operator bit_slicebit_sliceBitSliceBitSliceBitSlice
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.
