Subject [jira] [Created] (IMAGING-186) Add sCAL support to PNG reading and writing
Date Sat, 09 Jul 2016 00:49:11 GMT
Ric Emery created IMAGING-186:

             Summary: Add sCAL support to PNG reading and writing
                 Key: IMAGING-186
             Project: Commons Imaging
          Issue Type: Improvement
          Components: Format: PNG
            Reporter: Ric Emery
            Priority: Minor

It would be nice if the optional PNG - Physical Scale - sCAL chunk could be read and written.

For my use case, the pHYs chunk is not a good alternative. the pHYs x and y values are ints
which lose necessary precision.

I have a patch (with junits) ready for your review if you are interested.
