Hi Cyril, >However, when I want to apply a Gaussian Blur (for instance), the software sents back a message telling that the "dataset" input hasn't been provided. I guess it's a preprocessor issue.
Another possibility is that there actually is no Dataset. A Dataset[1] is an ImageJ2 construct, and by default would not be produced by opening an image with an ImageJ 1.x command. You can ensure a Dataset is available by using an ImageJ2 I/O plugin (e.g. File > Import > Image...) or turn on synchronization[2]. Once we get the synchronization step to be more performant, it will be made automatic. >how is the preprocessing order decided ? All Preprocessors[3] are SciJava Plugins, which are accessed in order of priority[4,5] >Could you point me to some existing preprocessor that does most of the logic so I don't have to re-implement simple operations ? The ActiveDataset preprocessor[6] is what populates single @Dataset parameters. There's also an ImagePlus version[7] for making @ImagePlus work. >http://cyrilmongis.net/img/imagejfx-screenshot.jpg This is fantastic. Is your source code openly available? I'm interested in JavaFX - for cross-platform distribution more than as a library, but would still be great to see what you're doing. Thanks for keeping us up to date, let us know how it goes and if you run into any more roadblocks (or if any of this is unclear)!
