Hi all, I’m newbie in module development using Ignition SDK. I tried the examples and I focused on the Vision Component Example. I am trying to develop a new component to connect to an IP camera using OpenCV. Right now my code generates a .modl file, but maybe I’m doing things wrong when I repaint…

You’re getting a NullPointerException in paintComponent method at OCRComponent.java:116. You’re dereferencing a null value somewhere in that method. Maybe the cam variable, or maybe cam.lastFrame.
