RoiCollection

The Roi collection plugin can be used to do data reduction on the image by providing a large number of Roi. The result will a spectrum of data. The spectrum (command readSpectrum) is containing the ROI integration value of the pixels.

In addition to the statistics calculation you can provide a mask file (setMask command or MaskFile property/attribute) where null pixel will not be taken into account.

If you have a detector with pixels which randomly return wrong high count rate, you can use the OverflowThreshold attribute to cut off those defective pixels.
