Struct PixelDensity

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

Available on crate feature dep_image only.

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

pub fn dpi(density: u16) -> PixelDensity

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

Trait Implementations

impl Clone for PixelDensity

fn clone(&self) -> PixelDensity

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PixelDensity

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for PixelDensity

fn default() -> PixelDensity

Returns a pixel density with a pixel aspect ratio of 1

impl PartialEq for PixelDensity

fn eq(&self, other: &PixelDensity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
