Struct ScaleOffset 

Source 
pub struct ScaleOffset {
    pub scale: f64,
    pub offset: f64,
}
Expand description

Per-band GDAL SCALE/OFFSET pair: physical = raw * scale + offset.

Fields§

§scale: f64

Raw-sample multiplier; missing metadata defaults to 1.0.

§offset: f64

Value added after scaling; missing metadata defaults to 0.0.

Implementations§

Source§

impl ScaleOffset

Source

pub const IDENTITY: Self
