Struct LogicalSize 

#[repr(C)]
pub struct LogicalSize {
    pub width: f32,
    pub height: f32,
}

Fields

width: f32

height: f32

Implementations

impl LogicalSize

pub fn scale_for_dpi(&mut self, scale_factor: f32) -> Self

Scales the size in-place by the given DPI scale factor and returns self.

pub const fn from_main_cross( main: f32, cross: f32, wm: LayoutWritingMode, ) -> Self

Creates a LogicalSize from main and cross axis dimensions.

impl LogicalSize

pub const fn main(&self, wm: LayoutWritingMode) -> f32

Returns the main-axis dimension for the given writing mode.

pub const fn cross(&self, wm: LayoutWritingMode) -> f32

Returns the cross-axis dimension for the given writing mode.

pub const fn with_main(self, wm: LayoutWritingMode, value: f32) -> Self

Returns a new LogicalSize with the main-axis dimension updated.

pub const fn with_cross(self, wm: LayoutWritingMode, value: f32) -> Self

Returns a new LogicalSize with the cross-axis dimension updated.

impl LogicalSize

pub const fn new(width: f32, height: f32) -> Self

pub const fn zero() -> Self

pub fn to_physical(self, hidpi_factor: f32) -> PhysicalSize<u32>

Converts to physical pixel size by multiplying by the DPI factor.
