renchap / shrine-blurhash Goto Github PK

Provide an option to test the mime-type of the attached file and avoid running blurhash if this is not an allowed mime-type.

Need to check how to do so, can we re-use existing shrine plugins, or directly their metadata? Should we detect metadata automatically?

Structure is already in place, and examples are here: Gargron/blurhash#7 (comment)

Those needs tests as well.

The various options and ways to use this plugin should be documented

Similar to what I did here: shrinerb/shrine#457

This makes it so the plugin adds the methods to compute the blurhash but does not run them automatically, allowing the user to do it themselves in their own add_metadata block, or to run it conditionally.

Current tests are passing on my mac, but not in GH actions.
I guess this is because two different libvips versions are used, we should use the latest one in CI.

Currently we extract every pixels from the source image into an array, then compute blurhash based on it.
We should allow to resize the image before computing Blurhash to reduce memory allocations and get better performance.

Resize dimensions should be configurable and deactivable, but enabled by default.

Upload .jpg file and everything works fine.

We need to test for more cases:

• Some additional images
• Errors handlers
• Directly calling methods
• Custom extractor
