How to reduce uploaded file size?

Well, part of OpenCV can be used in Ignition via a third-party module–Mine, actually. (The cv2 bindings work a bit different in jython vs. python, though, and some features aren’t supported in Java.) However, as noted in the other thread, Java has built-in image manipulation tools, starting with ImageIO. You can use these from jython by importing the necessary classes.
