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::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: PixelDensityUnitThe unit in which the density is measured
Implementations§
Source§impl PixelDensity
impl PixelDensity
Sourcepub fn dpi(density: u16) -> 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.
