Are there any out there?
And are there any tools/plugins to do this on your own website?
You can also paste the screenshot into Photopea and draw into it, crop it etc.
BTW. I am an author of Photopea :) It has an API, that allows embedding it into a website (https://www.photopea.com/api/playground), but I am not aware of any large website using it.
You can start by making a PPTX file parser, or PPTX to HTML converter, and then you can start adding some user interface, etc.
Most of the time I don't bother to put a screenshot since I have to :
- open my screenshot program - save the screenshot somewhere on my disk where I will find it later - remember which website doesn't suck where to upload the screenshot - actually upload the screenshot - paste a link
I'm not a JS bloat fan but int this case I'd rather take the bloat ;-)
Most image hosting sites like imgur let you paste an image from your clipboard (I think you can even do minor editing on their site now). Forums are also starting to allow pasting of images such as Discourse.
An editor embedded might be a fun project but it's completely unnecessary.
There is a write up on the integration here - https://blog.balsamiq.com/uxstackexchange/
Not embedded and it's horribly expensive, but very nice. There are a bunch of similar systems, but not quite as smooth.
draw.io is licenced under APL and usable. https://github.com/jgraph/drawio
Then there is the horrible but very practical: https://docs.google.com/drawings/
I wouldn't recommend trying to track it down, though.
See this for example: https://github.com/Immortalin/Greeting-Card-Creator
https://github.com/thenickdude/chickenpaint
But I take it you meant more like Visio or Powerpoint style stuff, for that I got nothing.
