// MagickChannelFxImage() applies a channel expression to the specified image.
// The expression consists of one or more channels, either mnemonic or numeric
// (e.g. red, 1), separated by actions as follows:
//
//   <=>     exchange two channels (e.g. red<=>blue)
//   =>      transfer a channel to another (e.g. red=>green)
//   ,       separate channel operations (e.g. red, green)
//   |       read channels from next input image (e.g. red | green)
//   ;       write channels to next output image (e.g. red; green; blue)
