Channel Calculator XTension

The channel calculator XTension can perform simple arithmetic operations on any two channels and was inspired by the ImageJ image calculator. * Implemented so far are Add, Subtract, Multiply, Divide. * A scaling factor can be set for each channel individually. * A new channel is created (and uniquely named), which can be clipped (using min / max thresholds) and / or normalised (values scaled to the min / max of the image datatype, e.g. 0-255 for an 8 bit image). * The "Live" tick at the bottom left corner visualises changes interactively. * Otherwise, the "Preview" button evaluates the operation for the current time point and "Apply operation to all timepoints" evaluates the operation for all the timepoints (may take time). This is a Python XTension (tested with 2.7.10) which relies on TkInter for the graphical interface and Numpy for the calculations. It also uses two of my "glue" libraries, TkDialog.py and BridgeLib.py, as well as the Imaris icons in the icons folder which were kindly provided by Bitplane. The latest version of this software is available from my github repository: https://github.com/zindy/Imaris/ The XTension and libraries are provided under the permissive Apache License v2.0.
