Struct DevicePixels 

Source
#[repr(transparent)]
pub struct DevicePixels(pub i32);
Expand description

Represents physical pixels on the display.

DevicePixels is a unit of measurement that refers to the actual pixels on a device’s screen. This type is used when precise pixel manipulation is required, such as rendering graphics or interfacing with hardware that operates on the pixel level. Unlike logical pixels that may be affected by the device’s scale factor, DevicePixels always correspond to real pixels on the display.

Implementations§

Source§

impl DevicePixels

Source

pub fn to_bytes(self, bytes_per_pixel: u8) -> u32

Converts the DevicePixels value to the number of bytes needed to represent it in memory.

This function is useful when working with graphical data that needs to be stored in a buffer, such as images or framebuffers, where each pixel may be represented by a specific number of bytes.

§Arguments
  • bytes_per_pixel - The number of bytes used to represent a single pixel.
§Returns

The number of bytes required to represent the DevicePixels value in memory.

§Examples
let pixels = DevicePixels(10); // 10 device pixels
let bytes_per_pixel = 4; // Assume each pixel is represented by 4 bytes (e.g., RGBA)
let total_bytes = pixels.to_bytes(bytes_per_pixel);
assert_eq!(total_bytes, 40); // 10 pixels * 4 bytes/pixel = 40 bytes
