Struct image::jpeg::PixelDensity
source · [−]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
