The annotation masks disappear when clicked on Next button

[nikhil-occipitaltech]

I am able to export the annotated masks but as soon as I click on the "next" so that I can annotate the other images, the masks previously made are gone. We have to annotate the images again.

It seems as if as soon as we hit "next", the app is removing the overlaid mask that has just been made and I am left with nothing. I have just cloned the library and started working.

@nikhil-occipitaltech This is a UI widget only. You have to take care of how to store the annotation data.

I believe I have used an older version of this tool and it used to save the annotated masks on the fly. However I didn't set the tool that time and it is possible that some modification may have taken place that I am unaware of. Would be helpful if I you could tell me how do I get an auto save functionality like the one label me has.

@nikhil-occipitaltech You can implement whatever operation in the callback functions. See the demo example.

@kyamagu I think it worth notifying if user didn't export annotations. Or if annotation was changed after last export

@arogozhnikov I did not export the annotation. I just annotated and moved to next image.
