Use geometry with image
Select optional geometry file
By default geometry data comes from DB associated with experiment or detector. Optional geometry file can be specified through the click on Geometry Control Node to deal with parameters window.
Click on "select" button and select desired geometry file, e.g.
Use Geometry without input array
Add the Geometry Control Node as usually and remove input terminal for arr3d. Click on "Apply" and use any geometry output parameters except "image".
RoiArch
Simple example
In simple case we use 2D image as input array without mask and ImageViewer with bin numbers in stead of actual scales for radial and angular dimensions.
...
Image can be moved and zoomed by click-and-drag and scrolling mouse, respectfullyrespectively.
ArchROI can be adjusted using 3 control points for center, external radius and entire rotation, internal radius and arch angular size. Alternatively, ArchRoi parameters can be adjusted using editor for parameters in the left side of the window. Click on "Apply" button after mask parameters are set.
...
Then build other control nodes as in previous examples, click on "Apply" button, etc.

NEW:
- in node Geometry separate arrays are combined in lists of index and coordinate arrays
- new nodes Mask3dFrom2d and TableFromArr3d
Example shows how to
- use epixquad:raw:raw (Array3d) and epixquad:calibconst (dict) as input to Geometry to generate image (Array2d),
- pass this image to RoiArch input, draw/edit arch, get Mask (Array2d) shaped as input image,
- use node Mask3dFrom2d with input mask2d from RoiArch and inds_xy from Geometry to generate 3-d mask array shaped as raw data,
- use nodes TableFromArr3d to convert 3-d mask to 2-d table of segments (without Geometry) to plot with ImageViewer.1
Potential extension of the node Geometry for 3-d mask output (TEMPORARY FOR PRESENTATION ONLY)
AMI issues
- Mask 3-d can be converted directly in the node Geometry (Mask3dFrom2d may not be required...),
- it needs in optional input parameters
- AMI does not work correctly with default input terminals
- unused terminals must be remover interactively
- if intermediate terminal removed input is moved to previous one...
- Also need in a few parameters in TableFromArr3d, but
- AMI fails to pickle qt modules (ComboBox, etc) and crashes...

PythonEditor for calib components of epix10ka and epixhr detectors
This example shows how to access in ami all components of the det.raw.calib(...) method such as calibration constants, per-panel trbit and asicPixelConfig, per-event gain factors and pedestals, mask, common mode correction, etc.

Code example for PythonEditor
In this example the PythonEditor box receives input objects for raw (np.ndarray), config, calibconst, accesses and prints internal components of the det.raw.calib(...) method and returns 2-d image for one retrieved arrays. For imaging, the 3-d array of common mode correction is converted to 2-d table of segments.
