bit_mask — Logical “AND” of each pixel using a bit mask.
The operator bit_mask 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.
Result image(s) by combination with mask.
Default value: 128
Suggested values: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096
If the images are correct (type) the operator bit_mask 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>:) If necessary an exception is raised.
