vitessce-image-viewer ("Viv")

A viewer for high bit depth, high resolution, multi-channel images using DeckGL over the hood and WebGL under the hood. To learn more about the "theory" behind this, look at this.

Build

To build the component alone via webpack use npm run-script build-component. To build the demo used for visual testing (seen on npm start), run npm run-script build-site.

Publish

To bump the version number, clean up/update the CHANGELOG.md, and push the tag to Github, please run npm version [major | minor | patch] depending on which you want. Then run ./publish.sh to publish the package/demo.

Development

Please install the Prettier plug-in for your preferred editor. (Badly formatted code will fail on Travis.)

For the demo, run npm start and you will be able to update the component and use the demo/src/App.js to visually test.

HTTP is acceptable but potentially slower than HTTP2. Our demo uses Google Cloud Storage, which is HTTP2 by default.

Due to difficulties around compiling shaders on Travis, unit tests and layer lifecycle tests are run locally as a pre-push hook. Travis runs a test build, linting, and prettier.

Browser Support

We support both WebGL1 and WebGL2 contexts, which should give near universal coverage. Please file an issue if you find a browser in which we don't work.
