PNG and MNG tools
Exif and TIFF/EP

PNG Web Site

This is an open source project to develop tools for preserving Exif information from digital cameras in PNG, MNG, and JNG files.

At present, no software has been developed. The project is in the planning phase, and a draft proposal is being written. Draft files are named "dnnn.html"; look for the one with the largest value of "nnn". Older drafts have been moved to the "history" subdirectory.

Hopefully, conversion tools (elif2png, png2elif, tife2png, and png2tife) will eventually be written.

A mailing list, "" has been established for discussing this project.
