The first tab of the configuration dialog contains General Settings. It is divided into a few groups:

Image display

  • Refresh rate in s: select a minimal time between consecutive frames
  • Aspect Ratio locked: sets the aspect ratio to 1:1 in the 2D-plot
  • Auto Down-Sample: turns on auto-down-sampling mode of pyqtgraph
  • Keep original coordinates: causes the 2D-plot axes transforms with image transformations
  • Pixel masks with zero values: causes that zero pixel values of mask image are interpreted as masking
  • Interrupt on source errors: stops live image viewing on image source errors
  • Display specific for a source: store/retrieve display parameters for an each image source separately
  • Lazy image slider:  set hdf5 reader of images to be lazy with respect to the frame slider
  • Maximal memory buffer size: number of image frames stored in the circular memory buffer

ROIs

  • ROIs Colors: allows to defined colors of ROIs selection frames. Colors are used cyclically
  • Show all ROIs values: calculates ROIs sum values for all ROI frames
  • Send ROIS values: sends ROIs sum values to LaVueController tango server

Statistics and 1d plots

  • Intensity scaling: applies the intensity display scaling to image statistics and 1d-plots
  • Calculate variance: show variance of the current flattened image

ZMQ security stream

  • Enabled: turns on sending the ZMQ security stream with basic informations about the image, e.g. maximal intensity
  • Automatic port: selects a port number for the ZMQ security stream automatically
  • Port: defines a port number for the ZMQ security stream

Tools

  • Store detector geometry for Angle/Q: store the detector geometry for the Angle/Q tool in the configuration settings
  • Geometry from a source: fetch geometry metadata from image sources like CBF or NeXus (if it is stored)

Sardana

  • Enabled: turns on communication with Sardana
  • Door: Door tango device to communicate with Sardana
  • Add ROIs to MG: causes the ROIs Apply button adds the corresponding ROIs aliases into the current Sardana Measurement Group
  • Fetch ROIs order: store/fetch order of ROIs in sardana environment
