[ImageJ-devel] ROI, Overlay and UI Implementation

[Mongis Cyril]

Dear all !

I have been working on this new interface for ImageJ which is part of my
PhD Thesis.
Here is a little video showing the status of the project.

I'm on the part where I start dealing with ROI, Overlay and all. However, I
don't know to which extent the Overlay/ROI data model goes. Could you point
me to the main classes to check when implementing a UI for Overlay/ROI? I
also have trouble understanding the concept of Overlay. If I understand
clearly, Overlay are just set of pixel data put on top of the image. But
also overlays can be defined by mathematic formula or just be a set of
pixels. At the end, they just cover the image. The Overlay tool just
generate set of pixels that represent an Overlay over the image. But in
ImageJ, the selection tools that we use don't really produce Overlay, they
produce selection I guess. Are those selection ROI ? I also don't see the
ROI in the imagej-common repository ? Are they simply in the scijava
repository ?

So in the end, could someone help by explaning or pointing ressources
explaning how the classes involved in ROIs and Overlays interact between
each other ?

I have already check the OverlayService, but I couldn't find any RoiService
:-(

Cheers,

Cyril
