public class VirtualChannels
extends Object

The current application for VirtualChannel sources is the following scenario: We have a labeling and want to display it using lookup tables to convert labels to ARGBType. From the same labeling we want to make multiple channels, e.g., selected ROIs, ROIs having property A, property B, etc. These could be added to BDV as individually converted images. So we could use N lookup tables to display N converted images. Instead, it is more efficient to merge the N lookup tables and then display only one converted image. We still want to be able to control display range and color settings for the N "virtual channels" individually. So VirtualChannels adds N fake sources to the BDV. Each fake source is used to control visibility and settings for one lookup table. Only one of the fake source will then actually render the converted img.
