Want to save the image

[Grant Smith]

I am using cornerstone with wc/wl and some annotation tools.

1. I want to take the image with its adjustments and annotations and save it as a new image.

2. I also want to take the image with its adjustments and annotations and save it in an intermediate way so that the annotations can still be moved, adjusted, and deleted if I load it in the future.

How can I get access to the flattened image for my question 1 and the layers and settings "object" for my question 2? If there is a good answer to question 2, how can I load that saved object in the future?

Thank you.

Does anyone have any ideas on this? I have looked at the various Cornerstone APIs for getting access to the canvas but that does not work (annotations do not show on the saved/exported canvas) and also is not a good way to save things so they will continue to be editable.

I don't use OHIF much anymore, but I did something with the Orthanc Stone Viewer that sounds like what you are looking for, but it requires a bit of customization.  There is a JS library called html2canvas:  https://html2canvas.hertzen.com/

Basically allows you to sort of take a screen grab of part of the DOM.  It works fairly well with what I did with the Stone Viewer.  I use that to capture a "Key Image", but the capture is static and does not allow any manipulation after the fact.

Thank you Stephen, this is very helpful! I will continue to pursue this solution as well as an editable one (where I would probably need to accumulate the changes from each tool and save them somewhere and replay them later).
