aurigma uploader + graphics mill - aurigma uploader + graphics mill

Graphics Mill does not have any image editing interface. It is a server-side image processing library which may draw rectangles programmatically. So you have to build your own client-side user interface to do drawing.

We have a separate image editor product called Customer's Canvas:

Using the editor application for your scenario may be a bit overkill, however, you might be interested to consider Design Atoms SDK from it to build your own editor interface.

Hope this makes sense.

Well, extending Upload Suite with functionality like this is not that easy, as it is based on an outdated JS framework (Google Closure). I would say it would be easier creating a new JS application based on some modern frontend framework (like Angular, Vue or React).

As for the image editor control, you have two options:

1. Build it yourself based on an HTML5 canvas (or use some ready solution like FabricJS). You may submit the result to the server as an SVG file. You may use Graphics Mill to convert it to the other file format. If you need the design to be editable, you will have to store canvas states somewhere, etc.
2. Use Design Atoms - it includes the component called Viewer which allows manipulating elements on a screen. The server-side part of Design Atoms helps to manipulate designs created on the front end - render an image (including PDF files), save/restore designs, process designs (e.g. populate it with some data, add/remove elements programmatically, etc).

Hope this helps.
