What does “Save externally” in a Signature column type mean?
I would guess it means save a copy to the user’s device as well?
It looks like this is a vestigial setting that is effectively always true now. This refers to the behavior of saving images to your data source (as opposed to directly in the sheet as base64).
Yes I think this was the case once. But in my testing this is (no more) the case.
@Steve_Howard Am i right with this?
- In a signature column it doesn’t matter if “Save externally” is enabled or disabled.
- The only images that are saved as a copy to the user’s device are from an image column and when you capture an image in a drawing column.
Can I disable the “save a copy to the user’s device”?
Can we get the Base64 from an image?
To the first question, yes, this setting doesn’t matter. As far as I can tell it used to do something, and now it doesn’t.
I don’t have a ton of context on how saving copies to the user’s device works. There’s currently not a way to get base64.
I think this will not be possible, because AppSheet uses the device’s Camera App. So when you capture an image with AppSheet, in fact you capture it with the device’s Camera App. That’s why the image is saved to the device as well.
