Draw or Sketch apps integration

I have a Xojo web based work order system for water/waste utilities where users log in and complete work orders while they are in the field.
I had a request from one user who uses iPads exclusively. They want to sketch out or draw an illustration of what was done and attach it to the work order.
Any ideas? Or are there any apps out there that Xojo can interface with?

Any help or advice would be appreciated…

You could probably do this with Xojo using a iosCanvas and then upload the images to a server somewhere…

Thanks, Greg. I am fairly new to Xojo so I will review the webinar on the canvas tool to see if I can make it work.
