Connector
open class Connector
| kotlin.Any | |
| ↳ | androidx.compose.ui.graphics.colorspace.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:
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 }

Public methods
transform
fun transform(
r: Float,
g: Float,
b: Float
): 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 |
| Return | |
|---|---|
| A new array of 3 floats containing the specified color | transformed from the source space to the destination space |

transform
open fun transform(v: FloatArray): FloatArray
Transforms the specified color from the source color space to a color in the destination color space.
| Parameters | |
|---|---|
| v: FloatArray | A non-null array of 3 floats containing the value to transform and that will hold the result of the transform |
| Return | |
|---|---|
| The | v array passed as a parameter, containing the specified color transformed from the source space to the destination space |
