Struct nannou::image::jpeg::PixelDensity [−][src]
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.
Trait Implementations
Returns a pixel density with a pixel aspect ratio of 1
This method tests for self
and other
values to be equal, and is used

Convert into T with values clamped to the color defined bounds Read more
Convert into T. The resulting color might be invalid in its color space Read more
Convert into T, returning ok if the color is inside of its defined range,
otherwise an OutOfBounds
error is returned which contains the unclamped color. Read more
