| FLinearColor FLinearColor::HSVToLinearRGB | ( | ) | const |
Converts an HSV color to a linear space RGB color
Initialize this Color based on an FString. The String is expected to contain R=, G=, B=, A=. The FLinearColor will be bogus when InitFromString returns false.
| InSourceString | FString containing the color values. |

Linearly interpolates between two colors by the specified progress amount. The interpolation is performed in HSV color space taking the shortest path to the new color's hue. This can give better results than FMath::Lerp(), but is much more expensive. The incoming colors are in RGB space, and the output color will be RGB. The alpha value will also be interpolated.
| From | The color and alpha to interpolate from as linear RGBA |
| To | The color and alpha to interpolate to as linear RGBA |
| Progress | Scalar interpolation amount (usually between 0.0 and 1.0 inclusive) |
| FLinearColor FLinearColor::LinearRGBToHSV | ( | ) | const |
Converts a linear space RGB color to an HSV color

| FORCEINLINE FColor FLinearColor::Quantize | ( | ) | const |
| FORCEINLINE FColor FLinearColor::QuantizeFloor | ( | ) | const |
Quantizes the linear color and returns the result as a FColor. This bypasses the SRGB conversion. Uses floor quantization, which does not match the GPU standard conversion. Restoration to float should be done with a +0.5 bias to restore to centered buckets. Do NOT use this for graphics or textures or images, use QuantizeRound instead.

Here is the call graph for this function: Here is the caller graph for this function:| FORCEINLINE FColor FLinearColor::QuantizeRound | ( | ) | const |
Quantizes the linear color with rounding and returns the result as a FColor. This bypasses the SRGB conversion. QuantizeRound can be dequantized back to linear with FColor::ReinterpretAsLinear (just /255.f) this matches the GPU UNORM<->float conversion spec and should be preferred

Quantizes the linear color and returns the result as a FColor with optional sRGB conversion. Clamps in [0,1] range before conversion. ToFColor(false) is QuantizeRound
