Description

disp_channeldisp_channelDispChanneldisp_channelDispChannelDispChannel 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 ChannelChannelChannelChannelChannelchannel 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_imagedisp_imageDispImagedisp_imageDispImageDispImage.

List of values: 1, 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

Example (C)

read_image(Image,"patras") ;
count_channels (Image, &Channels)
for (i = 1; i <= Channels; i++) {
  disp_channel (Image, WindowHandle, i) ;
}

Example (HDevelop)

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

Example (HDevelop)

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

Example (HDevelop)

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

Example (HDevelop)

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

Result

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