Well, part of OpenCV can be used in Ignition via [a third-party module](http://forum.inductiveautomation.com/t/automation-professionals-image-streamer-driver-module/29371)–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](https://docs.oracle.com/javase/8/docs/api/javax/imageio/ImageIO.html). You can [use these from jython](http://forum.inductiveautomation.com/search?q=ImageIO) by importing the necessary classes.
