Image Viewer is another addon supported by Feedback. This function will surely make things much easier for the Editor’s users.
Feedback, as its name suggests, gives the possibility of inserting feedback messages based on function calls from other modules. Just like in case of True/False and Connection addons, Image Viewer can now comunicate with Feedback, which means that changing frames enables displaying the Feedback modules’ content, i.e. the Image Viewer addon sends ValueChanged type of events to Event Bus when a frame is changed.
Updated documentation on an Image Viewer addon is available here. The example of Image Viewer and Feedback communication is presented here.
