Description

The operator select_grayvalues_from_channelsselect_grayvalues_from_channelsSelectGrayvaluesFromChannelsSelectGrayvaluesFromChannelsSelectGrayvaluesFromChannelsselect_grayvalues_from_channels selects gray values from the different channels of MultichannelImageMultichannelImageMultichannelImageMultichannelImagemultichannelImagemultichannel_image. The channel number for each pixel is determined from the corresponding pixel value in IndexImageIndexImageIndexImageIndexImageindexImageindex_image. Note, IndexImageIndexImageIndexImageIndexImageindexImageindex_image is allowed to have an arbitrary number of channels for reasons of backward compatibility, but only the first channel is considered.
