Use this function to mask a source image with an image of the multiphase type. The function extracts from the input image only those pixels that have the corresponding pixels in the mask image belonging to the selected Phase. The pixels that do not fall under the mask are set to zero.

If the Input and Mask images or selections are different sizes, one or both of them will be clipped to match the minimal horizontal and vertical dimension of the images or selected regions of interests. See Arithmetic/Logic for more details.

If you choose this command, the following options will become available:
