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
