open class Connector

A connector transforms colors from a source color space to a destination color space.

A source color space is connected to a destination color space using the color transform C computed from their respective transforms noted Tsrc and Tdst in the following equation:

See equation

The transform C shown above is only valid when the source and destination color spaces have the same profile connection space (PCS). We know that instances of ColorSpace always use CIE XYZ as their PCS but their white points might differ. When they do, we must perform a chromatic adaptation of the color spaces' transforms. To do so, we use the von Kries method described in the documentation of Adaptation, using the CIE standard illuminant D50 as the target white point.

Example of conversion from sRGB to DCI-P3:

val connector = ColorSpaces.Srgb.connect(ColorSpaces.DciP3);
val p3 = connector.transform(1.0f, 0.0f, 0.0f);
// p3 contains { 0.9473, 0.2740, 0.2076 }

open fun transform(v: @Size(min = 3) FloatArray): @Size(min = 3) FloatArray

Transforms the specified color from the source color space to a color in the destination color space.

Parameters
`v: @Size(min = 3) FloatArray`	A non-null array of 3 floats containing the value to transform and that will hold the result of the transform

Returns
`@Size(min = 3) FloatArray`	The `v` array passed as a parameter, containing the specified color transformed from the source space to the destination space

fun transform(r: Float, g: Float, b: Float): @Size(value = 3) FloatArray

Transforms the specified color from the source color space to a color in the destination color space. This convenience method assumes a source color model with 3 components (typically RGB). To transform from color models with more than 3 components, such as CMYK, use transform instead.

Parameters
`r: Float`	The red component of the color to transform
`g: Float`	The green component of the color to transform
`b: Float`	The blue component of the color to transform

Returns
`@Size(value = 3) FloatArray`	A new array of 3 floats containing the specified color transformed from the source space to the destination space
