Struct LinearImagePaint 

pub struct LinearImagePaint { /* private fields */ }

Opt-in linear-sRGB image sampling parameters. Only bounded encoded-sRGB sources are supported here; this is not a wide/HDR texture descriptor. RGB rows multiply decoded [R,G,B,1], then vignette darkens, then RGB clips and encodes to SDR sRGB. Alpha is preserved before native coverage/opacity.

Implementations

impl LinearImagePaint

pub fn new(rows: [[f32; 4]; 3], vignette: [f32; 4]) -> Result<Self>

Vignette = intensity, inner radius, positive feather, roundness. Radius units refer to the shortest source edge; roundness 0 follows its ellipse. Reject coefficients too large for finite f32 sampling arithmetic.

pub fn with_p3(self, p3: bool) -> Self

Select linear Display P3 working primaries.

pub fn is_p3(self) -> bool

Whether rows operate in linear Display P3.

pub fn rows(self) -> [[f32; 4]; 3]

Affine rows evaluated in the selected linear working primaries.

pub fn vignette(self) -> [f32; 4]

Intensity, inner radius, feather and roundness in source-image units.
