v2.0.0

Release 2.0.0 (September ?? 2025) -- compared to 1.1.0

This version is not API- or ABI-compatible with the previous versions.

MAIN CHANGES:

The core library (rawtoaces-idt):

• The core library has been renamed from rawtoaces_idt to rawtoaces_core.
• The Idt class has been renamed to rta::core::SpectralSolver, the public interface of the class has been cleaned up. Refer to core_usage.cpp for usage examples.
• The DNGIdt class has been renamed to rta::core::MetadataSolver, the public interface of the class has been cleaned up. Refer to util_usage.cpp for usage examples.
• Reshaping of spectral data has been added, so camera curves with other than 380..780nm with 5nm step sampling can be used.
• The dependency on boost::json has been removed in favour of nlohmann-json.

The util library (rawtoaces-util):

• The AcesRender class has been renamed to rta::util::ImageConverter, the public interface of the class has been cleaned up.
• The dependency on Libraw has been removed in favour of OpenImageIO.
• The dependency on AcesContainer has been removed in favour of OpenImageIO.
• The proprietary command line parcer has been replaced with OpenImageIO.

The command line tool (rawtoaces):

• Because of the new command line parser, all command line parameters have been changed. Please refer to rawtoaces --help, or README for more info.
• The switch to using OpenImageIO instead of Libraw directly required us to drop some optional command line parameters, since those options are not exposed in OpenImageIO yet. We had to drop the functionality, like providing black frames or dead pixel masks, etc. We will look at reintroducing those options on the OpenImageIO side in the future, if a need arises. Here is the list of dropped parameters:
  • -P - bad pixel mask
  • -K - dark frame
  • -j - fuji-rotate
  • -m - median filter
  • -f - four-colour RGB
  • -T - print Libraw-supported cameras
  • -F - use big file
  • -s - image index in the file
  • -G - green_matching() filter
• Functionality added: multiple crop modes supported via --crop-mode.
• Functionality added: specify output directories via --output-dir.
• Functionality added: automatically create missing output directories via --create-dirs.
• Functionality changed: rawtoaces does not overwrite existing files by default any more. Use --overwrite to override.

Other:

• Removed dependencies: boost, Libraw, AcesContainer.
• Added dependencies: OpenImageIO, nlohmann-json.
• The data files are now being installed into /usr/local/share, not /usr/local/include. The old path is still being resolved for backward compatibility.
