jsora

A frontend/browser javascript library for reading and writing OpenRaster (ORA) files.

what is supported

reading, extracting image data and metadata from ORA files
writing (creating new and modifying) ORA files, with any path structure and metadata
api support for layers / groups in a easy-to-use manner
rendering ORA files and edits to a browser canvas

Currently there is limited support for using multiple layers with the same path (same name in the same group)

I took note of another library with similar goals; https://github.com/zsgalusz/ora.js . However, I ended up not liking it because of the seeming lack of layer / group structure support.

for new style, all of the useful exports come from src/index.js . The repository is also preconfigured with webpack.
for 'old style', there will be a jsora.min.js file in the 'dist' dir built for use in a script tag after each release.
There is a useful html file in examples/tutorial.html which makes use of all of the high level features with some commentary. In addition, please feel free to reach out anytime for assistance. I am actively working on both developing this library and the standard itself.
