Allow JP2 (JPEG-2000) files #32

Closed nemobis closed 2 years ago

nemobis commented 8 years ago

jpegoptim works great for me; in my case I want to use the -S option to set a target size and downsize my JPEG file as needed. Some of my JPEG images are JPEG-2000 (JP2) files produced by ImageMagick (http://www.imagemagick.org/script/jp2.php ) and jpegoptim rejects them.

Is there any plan to make jpegoptim work with JP2 files too, at least for a subset of its functionality?

@nemobis the question was about JPEG files, not about JPEG2000 files. Convert those to JPEG first. (JPEG2000 decoders are currently in the process of being removed from a lot of software due to bugs, security holes, and lack of actual JPEG2000 images in the wild.)

I know the difference. My question is about JP2 files.

jpegoptim actually support JP2?
