I think this proposed change needs Working Group discussion before being merged.
- strange mention of YCbCr, which PNG does not support
- replaces 2^sampledepth with 16

Agreed with CL.
I added it to the discussion topics.
We should also mark it as informative.

I think this line can be removed. It accidentally adds an extra table inside the other table. Notice, it also never gets closed.

Also, I notice this is in § 4.2 Images - Reference image. Perhaps that section should instead be changed to say something like "1 to 16 bits, although not all bits might be used. The sBIT chunk (link) confines the bit range, and the cICP chunk (link) might declare the image is narrow range." Then the cICP chunk could have these example values instead of 4.2 |
