A pure rust library for reading / writing DNG files providing access to the raw data in a zero-copy friendly way. Also containing code for reading / writing a human-readable YAML representation of DNG tags / the IFD structure. DNG-rs also supports interacting with DCP (Dng Camera Profile) files, but that is on a best-effort basis since I was unable to find official documentation on that.
This library also contains a pair of cli tools for converting a DNG into a human-readable YAML representation and back.
These are kind of similar to dcpTool's
-c but use YAML rather than XML.
$ target/debug/dump_dng -h Dump the IFD metadata of a TIFF / DNG image to a human readable yaml representation Usage: dump_dng [OPTIONS] <FILE> Arguments: <FILE> input file to get the metadata from Options: -f, --dump-rational-as-float convert Rational and SRational types to float for better readability (this is lossy) -e, --extract extract strips, tiles and larger blobs into a directory. also write the ifd chain as a yaml file there -h, --help Print help information -V, --version Print version information
$ target/debug/compile_dng -h Assemble a DNG file from some of other dng files, plain raw files and metadata Usage: compile_dng [OPTIONS] --yaml <YAML> Options: --yaml <YAML> input YAML file to get the metadata from --dcp -b, --big-endian -h, --help Print help information -V, --version Print version information

This library should be in a usable state for many applications. However, a more high-level API is not implemented (yet?). For that (and support for other raw formats) you might want to use rawloader.
