Struct RDPoint 

pub struct RDPoint {
    pub codec: String,
    pub quality_setting: f64,
    pub bpp: f64,
    pub quality: f64,
    pub encode_time_ms: Option<f64>,
    pub image: Option<String>,
}

A point on a rate-distortion curve.

Fields

codec: String

Codec identifier.

quality_setting: f64

Quality setting used.

bpp: f64

Bits per pixel (rate).

quality: f64

Quality metric value (higher = better, e.g., SSIMULACRA2). For DSSIM, negate before adding.

encode_time_ms: Option<f64>

Optional encode time in milliseconds.

image: Option<String>

Optional image name.

Implementations

impl RDPoint

pub fn new( codec: impl Into<String>, quality_setting: f64, bpp: f64, quality: f64, ) -> Self

Create a new RD point.

pub fn dominates(&self, other: &Self) -> bool

Check if this point dominates another.

A point dominates another if it’s better on at least one objective and not worse on any objective.

Objectives:

• Lower bpp is better (smaller files)
• Higher quality is better
