Description🔗

disp_channelDispChannel displays an image in the output window. It is possible to display several images with one call. In this case the images are displayed one after another. If the definition domains of the images overlap only the last image is visible. The parameter Channelchannelchannel defines the number of the channel that is displayed. For RGB-images the three color channels have to be used within a tuple parameter. For more information see disp_imageDispImage.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

Number of channel or the numbers of the RGB-channels

Default: 11
Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 101, 2, 3, 4, 5, 6, 7, 8, 9, 10

Example🔗

(HDevelop)


read_image(Image,'patras')
count_channels (Image, Channels)
for I := 1 to Channels by 1
    disp_channel (Image, WindowHandle, I)
endfor

Result🔗

If the used images contain valid values and a correct output mode is set, disp_channelDispChannel returns 2 (H_MSG_TRUE). Otherwise an exception is raised.
