Generate image of the spectrum from outside component

[hamed-musallam]

in addition to exporting spectra as SVG, jpeg we need a way to capture and save them directly to the external data service. This has to be done from where our component is imported. for example, in Chemotion ELN they need to be able to capture the Blob of the generated image and store it as a blob in the database or store the image in the file server and store its path in the database

Could you please clarify how it should work at the point of view of the user ?

When should this image be generated ? Should the user click somewhere outside NMRium and at that time the NMRium file and PNG are generated at this moment ?

@lpatiny

The user can click somewhere outside NMRium or trigger an event in the NMRium Wrapper to generate an image as a blob to save it somewhere else, maybe in a database or upload it as a file in another file server.

I will ask Chandu to comment on this ticket

@CS76

can you comment on this and clarify the idea if I miss things

Use case: ELNs and repositories would like to create a thumbnail or preview of the spectra for the user to quickly identify the spectra and not have to load the spectra every time.

Trigger point:
Ideally, this will be triggered behind the scenes by the parent application (via the nmrium wrapper) and NMRium just has to pass back the image/png or image/jpg blob or SVG back as a response. This will then be handled by the parent application (saved to the file system on the server or to a database).
