Struct ColorGrading 

pub struct ColorGrading {
    pub global: ColorGradingGlobal,
    pub shadows: ColorGradingSection,
    pub midtones: ColorGradingSection,
    pub highlights: ColorGradingSection,
}

Configures filmic color grading parameters to adjust the image appearance.

Color grading is applied just before tonemapping for a given Camera entity, with the sole exception of the post_saturation value in ColorGradingGlobal, which is applied after tonemapping.

Fields

global: ColorGradingGlobal

Filmic color grading values applied to the image as a whole (as opposed to individual sections, like shadows and highlights).

shadows: ColorGradingSection

Color grading values that are applied to the darker parts of the image.

The cutoff points can be customized with the ColorGradingGlobal::midtones_range field.

midtones: ColorGradingSection

Color grading values that are applied to the parts of the image with intermediate brightness.

The cutoff points can be customized with the ColorGradingGlobal::midtones_range field.

highlights: ColorGradingSection

Color grading values that are applied to the lighter parts of the image.

The cutoff points can be customized with the ColorGradingGlobal::midtones_range field.

Implementations

impl ColorGrading

pub fn with_identical_sections( global: ColorGradingGlobal, section: ColorGradingSection, ) -> ColorGrading

Creates a new ColorGrading instance in which shadows, midtones, and highlights all have the same set of color grading values.
