bit_slicebit_sliceBitSliceBitSlicebit_slice (算子名称)

名称

bit_slicebit_sliceBitSliceBitSlicebit_slice — Extract a bit from the pixels.

参数签名

bit_slice(Image : ImageSlice : 位 : )

描述

该算子 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.

运行信息

多线程类型:可重入(与非独占操作符并行运行)。
多线程作用域:全局(可以从任何线程调用)。
在元组级别自动并行化。
在图像通道级别自动并行化。
Automatically parallelized on domain level.

参数表

Input image(s).

Bit to be selected.

Default: 8

Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 24, 30, 32

Minimum increment: 1

Recommended increment: 1

例程 (HDevelop)

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

例程 (C)

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);
}

例程 (HDevelop)

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

结果

If the images are correct (type) and 位位位位位位 has a valid value, 该算子 bit_slicebit_sliceBitSliceBitSliceBitSlicebit_slice 返回值 2 ( H_MSG_TRUE) . The behavior in case of empty input (no input images available) is set via 该算子 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.
