Q+ROI+Proj ToolΒΆ
Q+ROI+Proj Tool combines Angle/Q, ROI and Projections

Projections:
- Row/Column slice e.g.
9:10
or100:120:2
,<empty>
for all - Mapping: mean or sum
ROI:
- ROI alias(es) for roi tango devices
- Add to or Fetch from sardana environment
- Sum of the selected ROI or all ROIs. The used version can be selected in the configuration.
Geometry:
- Geometry: detector geometry parameters. They can be pass in both ways via **LavueController tango server
- theta angles or q-space selects the radial transformation
- Pixel intensity pointed by mouse and its position
The configuration of the tool can be set with a JSON dictionary passed in the --tool-configuration
option in command line or a toolconfig variable of LavueController.LavueState
with the following keys:
aliases
(list of strings), rois_number
(integer), mapping
(sum
or mean
string), rows
(string with a python slice), columns
(string with a python slice), units
(angles
or q-spaces
string), geometry
(string:float dictionary with the centerx
, centery
, energy
, pixelsizex
, pixelsizey
, detdistance
keywords)
e.g.
lavue -u q+roi+proj -s test --tool-configuration \{\"rois_number\":2,\"aliases\":[\"pilatus_roi1\",\"polatus_roi2\"],\"mapping\":\"sum\",\"rows\":\"10:200:5\",\"columns\":\"50:150\",\"units\":\"angles\",\"geometry\":\{\"centerx\":123.4,\"centery\":93.4,\"pixelsizex\":70,\"pixelsizey\":70.2,\"energy\":5050,\"detdistance\":50.5\}\} --start
