Overlay image in crystal snapshots

[dominikatrojanowska]

Is there any solution of passing overlay image to the snapshots taken automatically before DC? Currently our (Max IV) solution does not provide additional features like beam center, scale, shapes etc. We would like to have snapshots containing all the annotation that are added while taking a snapshot with the sample control button.

The snapshot taken with sample control:

The snapshot taken automatically before DC:

In general MXCuBE code for those two scenarios logic is a bit different. In first case the overlay_data is passed along to the camera/snapshot endpoint https://github.com/mxcube/mxcubeweb/blob/c44fc17b6756052f5f09e553acf10718ef97e25e/ui/src/api/sampleview.js#L81 while in the second case it is triggered by mxcubecore and no overaly is passed to take_snapshot method. Thus a the DC snapshot looks a bit different.
