Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inPixelA | AvlNet.Pixel | |||
| inPixelB | AvlNet.Pixel | |||
| inKL | float | <0.0f, INF> | 1.0f | The luminance weighting factor (best to use 1.0 for graphic arts and 2.0 for textiles). Default value: 1.0f. |
| inKC | float | <0.0f, INF> | 1.0f | The chroma weighting factor (usually 1.0). Default value: 1.0f. |
| inKH | float | <0.0f, INF> | 1.0f | The hue weighting factor (usually 1.0). Default value: 1.0f. |
| inK1 | float | <0.0f, 1.0f> | 0.045f | The secondary chroma weighting factor (best to use 0.045 for graphic arts and 0.048 for textiles). Default value: 0.045f. |
| inK2 | float | <0.0f, 1.0f> | 0.015f | The secondary luminance weighting factor (best to use 0.015 for graphic arts and 0.014 for textiles). Default value: 0.015f. |
 | outDistance | float |
