pub struct PixelDensity {
    pub density: (u16, u16),
    pub unit: PixelDensityUnit,
}
Expand description

Represents the pixel density of an image

For example, a 300 DPI image is represented by:

use image::jpeg::*;
let hdpi = PixelDensity::dpi(300);
assert_eq!(hdpi, PixelDensity {density: (300,300), unit: PixelDensityUnit::Inches})

Fields

density: (u16, u16)

A couple of values for (Xdensity, Ydensity)

unit: PixelDensityUnit

The unit in which the density is measured

Implementations

Creates the most common pixel density type: the horizontal and the vertical density are equal, and measured in pixels per inch.
