libdng

This is a library for making it easier to generate valid DNG files following the Adobe Digital Negative specification. This library is written for writing pictures created with Megapixels but should be useful for any photography applications.

The documentation can be found on https://libdng.me.gapixels.me/

Main features are:

  • Writing DNG 1.4.0 compliant TIFF files
  • Parsing DCP files for extra color processing metadata
  • Some DNG reading support for the dngmerge utility
  • Isolating applications from the changing libtiff APIs

This library also builds the makedng utility which allows generating a .dng file by hand from a raw sensor dump so it can be loaded in regular image processing software and a dngmerge utlity for combinding an existing DNG file with new color calibration tags from a DCP file.
