v0.3.2

Crates.io | Docs

This release has an MSRV of 1.82.

Added

• Add interpolate_unpremultiplied and gradient_unpremultiplied for interpolating in unpremultiplied (straight) alpha space.

  While such interpolation will often give perceptually undesired results, this allows using Color to implement rendering features where such interpolation is specified, like in the HTML Canvas element. (#185 by @sagudev)

Changed

• Specify XYZ-D65 color space conversion matrices as exact rationals. (#171 by @tomcur)
• Improve documentation of AlphaColor vs PremulColor to clarify alpha premultiplication, and make both types more discoverable from each other. (#190 by @tomcur)

New Contributors

• @ProgramCrafter made their first contribution in #186
• @sagudev made their first contribution in #191

v0.3.0

Crates.io | Docs

This release has an MSRV of 1.82.

Added

• Support converting between color spaces without chromatic adaptation, thereby representing the same absolute color in the destination color space as in the source color space. (#139, #153 by @tomcur)

  • Add absolute color conversion matrices for ProPhoto RGB, ACES2065-1 and ACEScg for faster conversion without chromatic adaptation to and from these color spaces. (#156, #164, #165 by @tomcur)

  Note to ColorSpace implementers: the WHITE_POINT associated constant is added to ColorSpace, defaulting to D65.
  Implementations with a non-D65 white point should set this constant to get correct default absolute conversion behavior.

• Support manual chromatic adaptation of colors between arbitrary white point chromaticities. (#139 by @tomcur)

• Add Missing::EMPTY to allow getting an empty Missing set in const contexts. (#149 by @tomcur)

• Add From<AlphaColor<_>> for DynamicColor conversions for all color spaces that have a direct runtime representation in ColorSpaceTag. (#155 by @LaurenzV)

• Add usage examples for DynamicColor::interpolate and gradient. (#158, #159 by @tomcur)

Changed

• Breaking change: the deprecated conversion From<Rgba8> for PremulColor<Srgb> has been removed. Use From<PremulRgba8> for PremulColor<Srgb> instead. (#157 by @tomcur)
• Improve no_std support. (#146 by @waywardmonkeys)
• Make {AlphaColor, OpaqueColor, PremulColor}::to_rgba8 faster. (#166 by @tomcur)

Fixed

• Correctly determine analogous components between ACES2065-1 and other color spaces when converting,
  to carry missing components forward when interpolating colors with missing components in the ACES 2065-1 colorspace. (#144 by @tomcur)
• Fixed powerless hue component calculation for the HWB color space. (#145 by @tomcur)

Fixed

• Specify some ColorSpace::WHITE_COMPONENTS to higher precision. (#128, #129 by @tomcur)

Color 0.1.0

We are proud to announce that we have released v0.1.0 of Color!

The Color library provides functionality for representing, converting, parsing, serializing, and manipulating colors in a variety of color spaces. It closely follows the CSS Color Level 4 draft spec.
