We had discussed this previously just for the purpose of rotating
images. And we recently revisited the idea when a university student was
working on the MaharaDroid app and was researching some Javascript-based
systems for rotating images (and other manipulations).
As Gordon said, there are some mature existing libraries for this, and
we'd want to use one of those.
Additionally, as I mentioned on the other bug, the easiest way to
incorporate this into Mahara would be to put it in the File -> Contents
file editing area (the same place you can change a file's name, tags,
etc.)
Bonus points for somehow incorporating it into the file upload system,
but that would be more challenging.

Title:
Simple image editor for basic manipulation
Status in Mahara:
Triaged
Bug description:
New Feature Request
Mahara is an incredibly visual tool, and I've seen issues with displaying
images often enough that I thought it was worth suggesting this as a useful
feature. In an ideal world users will do all of their editing on dedicated
software before loading a finished image, but in reality it's not always an
option, and if mobile submission has been setup to allow users to send content
from their mobile devices straight to Mahara it becomes even more useful to
have these features.
When loading an image from a computer the orientation data associated
with the image doesn't always match what the user sees on their own
computer (especially Apple devices). Two basic editing tools would
greatly enhance Mahara functionality - a rotate image tool (by 90
degrees per click), and a crop tool to trim displayed images. There
are other features that could be added - but I believe those are the
two that would have the biggest impact.
Rather than suggesting something is created from scratch - there are existing
open source or free web applications (eg below) that might provide a starting
point for a tool that could be incorporated.
