# Adds `--full-size-preview` to `convert`/`ftpserver`: forces the DNG
# preview/thumbnail to be rendered from the full raw sensor data instead of
# using whatever (often much smaller) JPEG preview the camera embedded,
# matching Adobe DNG Converter's "Full Size JPEG Preview" behavior -- see
# rawler/src/dng/convert.rs's generate_preview(), which otherwise always
# prefers the camera's own embedded preview when one exists. Not upstream.
Patch0:         0001-full-size-preview.patch
# Adds a LibRaw-style "auto bright" exposure-normalization step to
# RawDevelop's default pipeline (rawler/src/imgop/develop.rs), used both by
# the --full-size-preview fallback render and by `dnglab convert`'s
# standalone raw-to-image mode. Without it, that render is plain WB + camera
# color matrix + sRGB gamma with no exposure adjustment, which looks
# noticeably darker/flatter for any properly-exposed (headroom-preserving)
# shot than what other raw viewers show -- e.g. swayimg's raw.cpp, which
# decodes via LibRaw's dcraw_process() with auto-bright on by default. Not
# upstream.

%description
DNGlab is a fast, cross-platform converter for camera RAW images to the
Digital Negative (DNG) format, written in Rust. It also supports the reverse
operation, extracting the original raw file that is embedded in a DNG.

%changelog
* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 0.8.0-5
- Add an auto-bright exposure-normalization step to RawDevelop's default
  pipeline, closing the gap between the --full-size-preview render and a
  properly-exposed shot as rendered by other raw viewers (e.g. swayimg,
  via LibRaw's dcraw_process() with its default auto-bright). See
  0002-auto-bright-preview.patch.

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 0.8.0-4
- 0.8.0-3 built with a stale cached copy of 0001-full-size-preview.patch from
  ~/.local/rpm/sources/dnglab/ (mx-rpm doesn't re-sync a local Patch0 already
  present there), so it shipped without the writer.rs fix below despite the
  changelog claiming it. Re-synced the source-dir patch copy and rebuilt.

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 0.8.0-3
- Fix --full-size-preview to actually produce a full-size preview:
  DngWriter::preview() (rawler/src/dng/writer.rs) was unconditionally
  resizing the preview subframe to fit 1024x768 regardless of source, so
  the 0.8.0-2 patch only changed where the pre-resize image came from
  (embedded JPEG vs. full raw develop) without changing the output size.
  Thread full_size_preview through to preview() and skip the resize cap
  when it's set.

* Sun Aug 30 2026 Lachlan Marie <lchlnm@pm.me> - 0.8.0-2
- Add patch for a --full-size-preview convert/ftpserver flag (renders the DNG
  preview/thumbnail from the full raw data instead of the camera's own,
  often much smaller, embedded preview)

* Sun Aug 30 2026 Lachlan Marie <lchlnm@pm.me> - 0.8.0-1
- Initial packaging
