HDF-5 Image importer: use specified pixel size

[briantoby]

The pixel size for varex hdf5 is automatically populated as 74.8 um.

Can this be changed so that GSAS2 enters the values from attributes "DetPixelSizeX" and "DetPixelSizeY"?

Example file: /home/beams/S1IDUSER/mnt/s1c/mpe_sep24/varexC/ -rw-rw-r-- 1 s1iduser xfdop 159M Oct 4 14:11 CeO2_1s_000212.vrx.h5 (copy in ~/Scratch)

I don’t see attributes "DetPixelSizeX" and "DetPixelSizeY" unless I am looking in the wrong place:

fp['misc'].keys() Out [10]: <KeysViewHDF5 ['BDSSlitsHCenter', 'BDSSlitsHSize', 'BDSSlitsVCenter', 'BDSSlitsVSize', 'DetADCoreVersion', 'DetAcqPeriod', 'DetAcqTime', 'DetArrayCounter', 'DetBinX', 'DetBinY', 'DetDataType', 'DetDriverVersion', 'DetFilePath', 'DetFirmwareVersion', 'DetFullFileName', 'DetGain', 'DetHDFPlugInVersion', 'DetManufacturer', 'DetMaxSizeX', 'DetMaxSizeY', 'DetMinX', 'DetMinY', 'DetModel', 'DetSDKVersion', 'DetSampleName', 'DetSaveDest', 'DetSerialNumber', 'DetSizeX', 'DetSizeY', 'DetTemperature', 'DetZ', 'IDEnergy', 'IDGap', 'NDArrayEpicsTSSec', 'NDArrayEpicsTSnSec', 'NDArrayTimeStamp', 'NDArrayUniqueId', 'timestamp']>

I do see 10 values (for 10 images) for 'DetBinX', 'DetBinY'. I presume that when you rebin, say to 4x4 those will be each be 4 and the image will be 720x720 rather than 2880x2880. Correct?

Can you point to a file that does have a pixel size in it? Also, if you do have a file with binning, I’d like to play with that too.

Newer files have the pixel size. Now using dark_0.2s_000360.vrx.h5

scp xgate.xray.aps.anl.gov:/home/beams/S1IDUSER/mnt/s1c/mpe_sep24/varexC/dark_0.2s_000360.vrx.h5 ~/Scratch

mismatch between # of values & # of images. Asking for more info

This has been addressed in b04610b, though further work may be needed if the format changes -- and I am suggesting that more work on HDF5 schemas would be a really good idea.
