The support in LibWeb is quite easy as the previous commits introduced helpers to support lab-like colors. Now for the methods in Color: - The formulas in `from_lab()` are derived from the CIEXYZ to CIELAB formulas the "Colorimetry" paper published by the CIE. - The conversion in `from_xyz50()` can be decomposed in multiple steps XYZ D50 -> XYZ D65 -> Linear sRGB -> sRGB. The two first conversion are done with a singular matrix operation. This matrix was generated with a Python script [1]. This commit makes us pass all the `css/css-color/lab-00*.html` WPT tests (0 to 7 at the time of writing). [1] Python script used to generate the XYZ D50 -> Linear sRGB conversion: ```python import numpy as np # http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html # First let's convert from D50 to D65 using the Bradford method. m_a = np.array([ [0.8951000, 0.2664000, -0.1614000], [-0.7502000, 1.7135000, 0.0367000], [0.0389000, -0.0685000, 1.0296000] ]) # D50 chromaticities_source = np.array([0.96422, 1, 0.82521]) # D65 chromaticities_destination = np.array([0.9505, 1, 1.0890]) cone_response_source = m_a @ chromaticities_source cone_response_destination = m_a @ chromaticities_destination cone_response_ratio = cone_response_destination / cone_response_source m = np.linalg.inv(m_a) @ np.diagflat(cone_response_ratio) @ m_a D50_to_D65 = m # https://en.wikipedia.org/wiki/SRGB#From_CIE_XYZ_to_sRGB # Then, the matrix to convert to linear sRGB. xyz_65_to_srgb = np.array([ [3.2406, - 1.5372, - 0.4986], [-0.9689, + 1.8758, 0.0415], [0.0557, - 0.2040, 1.0570] ]) # Finally, let's retrieve the final transformation. xyz_50_to_srgb = xyz_65_to_srgb @ D50_to_D65 print(xyz_50_to_srgb) ``` |

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibArchive: Archive file format support
- LibUnicode: Unicode and locale support
- LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
Code-related documentation can be found in the documentation folder.
