From 63b3f8f78510dc0ce4a5860145ed997c1a576169 Mon Sep 17 00:00:00 2001 From: "Vlad (Kuzmin) Erium" Date: Thu, 30 Oct 2025 20:32:32 +0900 Subject: [PATCH 01/15] ProPhotoRGB builtin transforms Add ProPhotoRGB (ROMM RGB) as a set of builtin transforms for color space conversions between ProPhotoRGB and ACES2065-1, including both native gamma 1.8 and sRGB gamma variants. Updates documentation: usage and available styles, registers the transforms in the registry. Adds comprehensive unit tests for registration, gamma curves, round-trip, and variant support.
