main.js - main entry point for program (just boilerplate to launch other scripts)
image_resize.js - responsible for:
- all image resizing
- reading file_paths.json to get the folder locations for 'images' and 'annotations'
- sending those paths to the frontend via ipc
- managing a big queue of images to be resized and sending queue details to main.html via ipc
schema.js - responsible for:
- serializing the requested schema to json and sending via ipc
- needs to make the json interpretable by the jsTree library
everything is in main.html, searching for 'function' will get you most of the main methods with a little comment above (for the important ones).
Some details:
- images are loaded from the 'thumbnail' folder, if they are only in 'full' or 'medium' size then they will not appear
- annotations are stored in the 'annotations' folder, unless specified elsewhere
- there are a few big arrays with all the information about image path, annotation, label, color, that are used to generate all the images These are: imgs (file paths), evts (store an internal event id), labels (mapping from event id -> label), label_to_color (what it sounds like).
- to see what it gets from the backend do Ctrl-F 'ipc' to find where it uses inter process communication library
For development execute npm start command. This will launch the program with hot-reload for all front end-changes (but not backend).
Build script is under 'scripts' in package.json, to build use command npm run-script build, which will build for your current OS. For any other build options refer to electron-build documentation.
Importantly after building you must copy over the desired schema folder, which goes in the root directory. Any images/annotations you would like to use must also be copied in (or linked to).
