Learn how to work with pre-annotations by acquiring a fundamental understanding of project configuration. The subsequent example demonstrates the process of uploading pre-annotations for image annotation. This procedure remains consistent across all project types. Sample files, JSON structures , and custom code are provided for each project type.
...
Once the rest of the project configuration is done, go to Advanced > Project Task > Custom code > On load. Add the following code, click on SAVE.
...
Create an input file containing two fields MediaURL and JsonData . The field JsonData should have the JSON data containing our pre-annotations. The JSON structure is as follows. Import it as a dataset.
