Changelog

Unreleased

3.6.1

Changed

  • All color class constructors are now public to avoid warning when using copy() (#65)
  • HSV.toSRGB() with NaN a hue value now returns a greyscale RGB color instead of a NaN color. (#67)
  • Update Kotlin to 2.1.0

3.6.0

Added

  • Publish artifacts for the watchosArm32 target (thanks @ReneeVandervelde)

Changed

  • Update Kotlin to 2.0.0

3.5.0

Added

  • Publish artifacts for the JS and wasmJs targets for the jetpack-compose extensions.
  • Added support to formatCssString and Color.parse for color spaces added in recent updates to the CSS color spec: oklab, oklch, srgb-linear, xyz-d50 and xyz-d65.
  • Added customColorSpaces for Color.parse and Color.formatCssString to allow non-standard color spaces to be used in color strings.
  • Added min and max properties to ColorComponentInfo to get the reference range for the component.
  • Support percentage format for all values in Color.parse with reference range scaling from the new drafts of CSS Color Module 4.
  • Added clamp() function to all color models to clamp the color components to their valid range.

Changed

  • Color.parse now parses lch() and lab() functions with the with D50 white points instead of D65 in order to comply with the latest draft of CSS Color Module 4.
  • Color.parse no longer clamps out-of-gamut values by default. Use the new clamp method on the returned color if desired.

Fixed

  • ColorSpace.equals will now properly return true when comparing color companions with the space they represent e.g. XYZ == XYZ65
  • Support the CSS "none" keyword for NaN values in Color.parse and Color.formatCssString

Added

  • hueAsRad(), hueAsGrad(), and hueAsTurns() extensions for HSL and HSV classes.
