Right, I get how to duplicate or remove frames using the inputContext (...) method - thank you very much for that.
Is the only way to analyse the content before choosing which frame to display, by adding a button to the interface? Ideally I would just like to carry out the analysis automatically. However, I think to get the pixel contents I need to do this in the engine() method - yet I want to set the frame in inputContext() which gets called before the engine method. So by the time I've viewed the pixel information in engine(), it's too late to set the frame in inputContext(). I hope this makes sense - can you help? Is it possible to read the pixel contents of the image and then set the frame number based on the pixel data? Any help is greatly appreciated - thank you! :-)
