Openjpeg could not encode 32bit RGB float image #1281

I am a professional video maker. A few days ago, I encoded a video clip to TIFF image sequence inside Adobe Premiere Pro CC 2019 with 32bit RGB float component. The file however, took a large number of Gigabytes from my hard disk. In order to shrink my file size but not losing any details from the original video, I chose to transcode the TIFFs to JPEG2000 lossless. To my disappointment, the openjpeg CLI software only threw me an error message: "bit depth 32 is not allowed ...." with nothing more. I expect your team to implement 32bit RGB support to the repository

@xingchenli1996 this is probably a translation issue, because the english word ‘expect’ is a very demanding term. You can not ‘expect’ a service or good from other people, without politeness, kindness, a favour, a kind word, a reciprocal service, or even some money.

I think/hope that you meant: “it would be very cool if you can add [whatever feature] to this product, and I’m willing to help with coding, knowledge, support, testing, money or whatever is needed. And thanks for the stuff already available”.

I know, languages/culture differences are hard to get.
