Joseph,

This thread from the xml-dev list might be of interest to you: http://lists.xml.org/archives/xml-dev/201612/msg00004.html. It discusses DFDL (Data Format Description Language), an XML schema used in parsing binary files (http://dfdlschemas.github.io/).

Hi Christian,

I recently had to deal with a Python library allowing to convert a png image into a matrix composed of pixel tuples [[(255,255,255), ], ...] which can then be changed and then saved back into png. I found it easy to manipulate it (ie, change colors, dimensions, etc...), so I was thinking that something similar in XQuery would be helpful for those working with images.

Cheers,
J.

Hi Joseph,

There is no existing library for accessing image data. I would
recommend you to take advantage of one of the various Java libraries.

What exactly would you like to do with the image information?

Cheers,
Christian
