Enum image::jpeg::PixelDensityUnit

source · [−]

pub enum PixelDensityUnit {
    PixelAspectRatio,
    Inches,
    Centimeters,
}

Expand description

Represents a unit in which the density of an image is measured

Variants

`PixelAspectRatio`

Represents the absence of a unit, the values indicate only a pixel aspect ratio

`Inches`

Pixels per inch (2.54 cm)

`Centimeters`

Pixels per centimeter
