tifuchs/orGUI: v1.4.0

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.
