color_models 1.1.0

A set of classes representing the CMYK, HSI, HSL, HSP, HSB, LAB, Oklab, RGB, and XYZ color spaces with methods to convert colors between each space.

1.1.0 March 15, 2021

• Implemented the Oklab color space as [OklabColor].

• Added the [castTo], [convert], [copyWith], [interpolate], and [withValues] methods to every color model.

• Deprecated the withXXX methods being replaced by the [copyWith] method.

• Updated the implementation of the [lerpTo] methods.

• Added the [ColorSpace] enumeration and extended it with the [from] method to convert colors to the color spaces defined by the enumeration.

• Extended Iterable<ColorModel> with the [augment] method, which generates new color palettes derived from the iterable.

1.0.0 March 11, 2021

• Migrated to null-safe code.

• Moved the [calculateDistance], [random], [randomHue] and [round] utility methods into a utility class: [ColorMath].

• Changed [ColorModel]'s [alpha] parameter from a positional parameter to a named parameter with a default value of 255.

0.3.0 September 21, 2020

• Normalized all [alpha] values to be on a 0 to 255 scale to be in line with Flutter's [Color] class. They were on a 0 to 1 scale.

• Renamed [HsvColor] to [HsbColor] to avoid a naming conflict with Flutter's [Color] class's [value] parameter.

• Renamed [interpolateTo] to [lerpTo].

0.2.8 March 29, 2020

• Removed [isBlack] and [isWhite] conversion condition from the CMYK color space.

• Added [isMonochromatic] conversion condition to the H color spaces.

• Rounding error fix calculating hues from [XyzColor]s. Affected some colors with RGB values equaling 255.

0.2.7 March 29, 2020

• Added the [interpolateTo] method to each color model.

• Override the conversion methods on each color model that return their own respective color spaces. Colors were being unnecessarily converted back and forth from RGB.

0.2.6 March 24, 2020

• Added the random factory constructor to each [ColorModel].

• The equality operator and some getters now rounds values to the millionth due to the slight loss of precision during conversions.

• The [hue] getter now calculates hues directly from RGB, rather than doing a full conversion to HSL.

• Added the [isMonochromatic] getter to each [ColorModel].

0.2.5+1 March 23, 2020

• Fixed a bug in the HSP to RGB conversion method.

0.2.5 March 22, 2020

• Added the [relative] parameter to the [warmer] and [cooler] methods.

0.2.4+2 March 22, 2020

• Added the [saturation] getter to [ColorModel].

0.2.4+1 March 22, 2020

• Added the [hue] getter to [ColorModel].

0.2.4 March 21, 2020

• Added the [inverted] and [opposite] getters, as well as the [warmer], [cooler], [rotateHue], and [withHue] methods to each [ColorModel].

0.2.3 March 18, 2020

• Added [alpha] values to all [ColorModel]s.

• Added withValue methods to all [ColorModel]s.

0.2.2 March 16, 2020

• Added [hex] getter to [ColorModel].

• Added [fromHex] static method to all [ColorModel]s.

• All [ColorModel]s are now @immutable.

0.2.1 January 15, 2020

• All [ColorModel]s now @override the toString() method.

0.2.0+1 January 15, 2020

• Documentation and formatting changes.

0.2.0 January 4, 2020

• To provide better support for 3rd party color models, [ColorModel]s are now requried to @override the [toRgbColor] method. All [ColorModel]s included in this library still use the color conversion methods found in the [ColorConverter] helper class, but the methods are now public.

0.1.2 July 31, 2019

• All [ColorModel]s now @override [hashCode].

0.1.1 July 25, 2019

• Added a private constructor to the [ColorConverter] class.

• Minor formatting changes.

0.1.0 July 23, 2019

• Initial release
