//! Interchange: camera-raw-settings (`crs:`) develop fields from XMP → our develop settings.
|
||
//!
|
||
//! Other raw developers store their edits as `crs:` properties in XMP sidecars, in DNG-embedded
|
||
//! XMP and in XMP preset files. This module maps the commonly used, documented-by-observation
|
||
//! fields to a *partial* [`DevelopSettings`](lightcraft_develop::DevelopSettings) JSON object
|
||
//! (only the fields present in the packet), which is then merged like a preset. Our pipeline is
|
||
//! not theirs, so the result is a best-effort approximation of the look, not a pixel match.
|
||
//! The full table is in `docs/xmp-interop.md`.
|
||
//!
|
||
//! Implemented from the public XMP specification (ISO 16684-1) and black-box observation of what
|
||
//! each field means; no third-party code or preset content was used.
