Struct luminance_glutin::LogicalPosition

pub struct LogicalPosition {
    pub x: f64,
    pub y: f64,
}

A position represented in logical pixels.

The position is stored as floats, so please be careful. Casting floats to integers truncates the fractional part, which can cause noticable issues. To help with that, an Into<(i32, i32)> implementation is provided which does the rounding for you.

Fields

x: f64

y: f64

Methods

impl LogicalPosition

pub fn new(x: f64, y: f64) -> LogicalPosition

pub fn from_physical<T>(physical: T, dpi_factor: f64) -> LogicalPosition where
    T: Into<PhysicalPosition>, 

pub fn to_physical(&self, dpi_factor: f64) -> PhysicalPosition

Trait Implementations

impl PartialEq<LogicalPosition> for LogicalPosition

fn eq(&self, other: &LogicalPosition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &LogicalPosition) -> bool

This method tests for !=.

impl Debug for LogicalPosition

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Into<(f64, f64)> for LogicalPosition

fn into(self) -> (f64, f64)

Performs the conversion.

impl Into<(i32, i32)> for LogicalPosition

fn into(self) -> (i32, i32)

Note that this rounds instead of truncating.

impl Clone for LogicalPosition

fn clone(&self) -> LogicalPosition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LogicalPosition

impl From<(i32, i32)> for LogicalPosition

fn from((i32, i32)) -> LogicalPosition

Performs the conversion.

impl From<(f64, f64)> for LogicalPosition

fn from((f64, f64)) -> LogicalPosition

Performs the conversion.
