bit_slicebit_sliceBitSliceBitSlicebit_slice (Operator)

Name

bit_slicebit_sliceBitSliceBitSlicebit_slice — Extract a bit from the pixels.

Signature

Description

The operator bit_slicebit_sliceBitSliceBitSliceBitSlicebit_slice 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.

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(Image,'fabrik')
for I:= 1 to 8 by 1
    bit_slice (Image, ImageSlice, I)
    threshold (ImageSlice, Region, 1, 255)
    dev_display (Region)
endfor

read_image(&ByteImage,"fabrik");
for (bit=1; bit<=8; i++)
{
  bit_slice(ByteImage,&Slice,bit);
  threshold(Slice,&Region,1,255);
  disp_region(Region,WindowHandle);
  clear(bit_slice); clear(Slice); clear(Region);
}

read_image(Image,'fabrik')
for I:= 1 to 8 by 1
    bit_slice (Image, ImageSlice, I)
    threshold (ImageSlice, Region, 1, 255)
    dev_display (Region)
endfor

read_image(Image,'fabrik')
for I:= 1 to 8 by 1
    bit_slice (Image, ImageSlice, I)
    threshold (ImageSlice, Region, 1, 255)
    dev_display (Region)
endfor

read_image(Image,'fabrik')
for I:= 1 to 8 by 1
    bit_slice (Image, ImageSlice, I)
    threshold (ImageSlice, Region, 1, 255)
    dev_display (Region)
endfor

Result

If the images are correct (type) and BitBitBitBitbitbit has a valid value, the operator bit_slicebit_sliceBitSliceBitSliceBitSlicebit_slice 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>)set_system("no_object_result",<Result>) If necessary an exception is raised.
