Description

disp_channeldisp_channeldisp_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 ChannelChannelChannelChannelchannel 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_imagedisp_imageDispImageDispImage.
