Feature Request

Add JP2 image support

Feature description

Just like #1497, it should be great if PDFKit could understand, parse and display JP2 image.

I use Sharp lib for managing image resize, and it can cope with all these kind of extensions.

Do you plan to add these in a near future?
Thanks

PDF does not support this image type. Even png is not supported directly. See https://pspdfkit.com/blog/2018/understanding-images-in-pdf/

Is necessary to convert the image to one of the supported images by pdfkit, before including in a document.

Adding the image conversion in pdfkit is not feasible

Thanks for your interesting link. I didn't know PDF was so specific with images.

But as a side note, he speaks of JP2 in his article here https://pspdfkit.com/blog/2018/understanding-images-in-pdf/#jpeg-2000 , so it is maybe possible to include it.

Yes its possible but undoable, would increase the bundle size a lot since it would require a dependency on a library that does the conversion.

What we can do is implement some way to implement image format through other packages, it can be a plugin system or some kind of image / resource container
