How to extend zune-image?

[SalOne22]

Hello, I am building my CLI image processing tool that leverages the usage of modern codecs such as mozjpeg and oxipng.

How can I extend the default zune encoders with those libraries? Ideally, I would like to create zune-mozjpeg or zune-oxipng crates to integrate these libraries with zune-image. Can I do that, or would it be better to create internal bindings? What approach would be more suitable?

Hi, I actually never thought of extending it this way

I don't have the capability to manage things like other encoders and decoders.

Encoders are implemented as traits so anything that can implement EncoderTrait is an encoder. A way may be extending ImageFormat enum with CustomEncoder(Box<dyn EncoderTrait>) then use save_with and pass the customer ebcoder enum with the encoder nested.

Lemme see if i can come up with a prototype.

Maybe add to ImageFormat custom field with trait that implements all required functions to get decoder, encoder and file format. Also add to Image struct write_with_encoder method that can accept any encoder, like image crate do.

yea, that is also possible. Will look into it
