Enum Length 

pub enum Length {
    Px(f64),
    Mm(f64),
    Mils(f64),
    Inch(f64),
}

A physical or device length.

Barcode geometry is specified in physical units — the X-dimension of a shipping label is 13 mil, not “3 pixels” — so lengths carry their unit and are converted against the output DPI.

Variants

Px(f64)

Device pixels, used as-is regardless of DPI.

Mm(f64)

Millimetres.

Mils(f64)

Thousandths of an inch. The conventional unit for barcode X-dimensions; 13 mil is the common shipping-label default.

Inch(f64)

Inches.

Implementations

impl Length

pub fn to_px(self, dpi: u32) -> f64

Convert to device pixels at dpi.

pub fn to_mm(self, dpi: u32) -> f64

Convert to millimetres at dpi (needed for SVG physical dimensions).
