This is a feature release with lots of additional bug fixes. Added a new dialog which automatically calculates the position of the Bragg peak, which helps to improve the U matrix the most and adds it to the list of reference reflections. Added a Bragg peak search, which searches for the center of mass in a small section of multiple images. This can be used to quickly find the image and position of a Bragg peak. To be used when an estimate of the Bragg position is already given (such as with the new Bragg peak dialog) Auxilliary counters (potential, temperature, ...) are now also integrated in all integration functions. A static background image can now be subtracted from the detector images. This can be used to subtract static sample environment scattering such as water or air (beamline background) scattering. Multiple scans can be concatenated and treated as a single scan. This is done to avoid high-intensity sample positions which would lead to damage to the detector (Thanks to Finn!). Positions of Bragg reflections can now be integrated as rocking scans. This enables fast conventional single crystal X-ray difffraction analysis of Bragg reflection structure factor. Strain with respect to the reference lattice can be added for epitaxially grown thin films. 2D ROI size can now be dynamically adjusted. Currently, the ROI size can be corected for Peak size increase due to scattered beam - detector inclination Peak size increase due to the illuminated sample size. Currently, the sample is approximated as a cuboid (size to be set in Advanced ROI options dialog) and its outlines are projected onto the detector. The orGUI hdf5 data base can now be compressed using hdf5plugin. This compression is not visible to the user, but reduces the file size by a factor of 2x - 3x. Calculation speed loss is possible and depends on the OS, available libraries , etc. See Issue #16 for an overview. Opening compressed data bases with external software requires the user to install and import hdf5plugin.
