A member of the Team first needs to authorize it.

I like this but I think the watermark should not be movable. instead it should be permanently attached to the image in a fixed location.

Not sure how to best make this happen quite yet but maybe you find a way :)

Hey @mfts, can you confirm if the pro version includes the watermark feature? What will be the default behaviour (open or close) if it's not included in the pro version? That way, I can make changes accordingly.

@ashrafchowdury this would most definitely be a pro feature.

it would be awesome if we could manipulate the image before it hits the client. so far I only know of a solution that involves S3 lambda.

If we manipulate the image most probably the watermark will fall into the empty space of the image.

It would be beneficial for us if we could display raw PDFs to the client instead of images to unlock new feature possibilities. What do you think about it?

Thanks for the initial project @ashrafchowdury.

We just shipped watermarking here #576. You might find the approach slightly differently.
