Feature request - annotation layer

[khem-so-usfws]

Hi all, When multiple images cover an area of interest, it would be nice to be able to non-destructively annotate images with polygons, lines, and/or text to indicate where a count begin and ends on a given image so that it's easier to avoid double-counting.

@khem-so-usfws Are your images georeferenced / orthorectified? If so, I could think of some options for DDG or, more likely, utility scripts to post process the counts.

If not, to do this would require the ability to align and overlay images. We thought about adding mosaic capabilities early on, but decided that there are already many existing tools out there, especially for drone images, and we wanted to keep DDG as compact and feature focused as possible.

I am happy to schedule a time to chat if you want to contact me directly. Email in my profile.

There is now the ability to use labelme to create polygon annotations that will be displayed in DDG. Additionally, there is a script in the extra_tools directory that will convert a GeoJSON polygon layer to an external annotation format that can be consumed by DDG. This functionality is available in the main repo and will be part of the 1.7.0 release, but will only have minimal documentation until it is further flushed out.

There are no controls yet to alter the color, fill, or line width of the external polygon annotations.
