Struct bevy_window::WindowResolution

pub struct WindowResolution { /* private fields */ }

Window Sizes

There are three sizes associated with a window. The physical size which is the height and width in physical pixels on the monitor. The logical size which is the physical size scaled by an operating system provided factor to account for monitors with differing pixel densities or user preference. And the requested size, measured in logical pixels, which is the value submitted to the API when creating the window, or requesting that it be resized.

The actual size, in logical pixels, of the window may not match the requested size due to operating system limits on the window size, or the quantization of the logical size when converting the physical size to the logical size through the scaling factor.

Implementations

impl WindowResolution

pub fn new(logical_width: f32, logical_height: f32) -> Self

Creates a new WindowResolution.

pub fn with_scale_factor_override(self, scale_factor_override: f64) -> Self

Builder method for adding a scale factor override to the resolution.

pub fn width(&self) -> f32

The window’s client area width in logical pixels.

pub fn height(&self) -> f32

The window’s client area width in logical pixels.

pub fn physical_width(&self) -> u32

The window’s client area width in physical pixels.

pub fn physical_height(&self) -> u32

The window’s client area height in physical pixels.

pub fn scale_factor(&self) -> f64

The ratio of physical pixels to logical pixels

physical_pixels = logical_pixels * scale_factor

pub fn base_scale_factor(&self) -> f64

The window scale factor as reported by the window backend.

This value is unaffected by WindowResolution::scale_factor_override.

pub fn scale_factor_override(&self) -> Option<f64>

The scale factor set with WindowResolution::set_scale_factor_override.

This value may be different from the scale factor reported by the window backend.

pub fn set(&mut self, width: f32, height: f32)

Set the window’s logical resolution.

pub fn set_physical_resolution(&mut self, width: u32, height: u32)

Set the window’s physical resolution.

This will ignore the scale factor setting, so most of the time you should prefer to use WindowResolution::set.

pub fn set_scale_factor(&mut self, scale_factor: f64)

Set the window’s scale factor, this may get overridden by the backend.

pub fn set_scale_factor_override(&mut self, scale_factor_override: Option<f64>)

Set the window’s scale factor, this will be used over what the backend decides.
