Struct `PixelDensity`

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

Represents the pixel density of an image

For example, a 300 DPI image is represented by:

use image::codecs::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

`impl PixelDensity`

fn dpi(density: u16) -> Self: Creates the most common pixel density type: the horizontal and the vertical density are equal, and measured in pixels per inch.
