Convert images to webp #47

Closed nh758 closed 10 months ago

nh758 commented 11 months ago

To reduce image size convert images to webp format.

Requirements

Background process converts image to webp via cli
- run in a worker
Can request a webp image (optional parameter of the GET /file route? or should we default to webp?)
- should resolve to the original if webp conversion not finished.

Tasks

[ ] Write Documentation

Reference

cwebp cli converts PNG, JPEG, or TIFF to webp https://developers.google.com/speed/webp/docs/cwebp
magick cli might be better to support more file types (including HEIC see https://github.com/digi-serve/ns_app/issues/339)
- but may require adding libraries for file types (required for webp and HEIC) https://imagemagick.org/script/formats.php
- magick can also resize images so could be used for #35 as well.
maybe consider other cli tools

Will need to include the cli tool in the docker image.
