Mask

The mask correction is very useful when you have some defective pixels on your detector sensor. Then you can provide a mask image file which can either applies a fixed value for those defective pixel (mask type == DUMMY) or sets those pixels to zero count (mask type = STANDARD).

To set the correction you must provide to the device a flatfield image file (setFlatMaskImage command) and then start the correction (start command).
