Struct Viewport 

pub struct Viewport {
    pub width: f64,
    pub height: f64,
    pub major: f64,
    pub minor: f64,
    pub aspect: f64,
    pub landscape: bool,
    pub portrait: bool,
    pub square: bool,
}

Struct representing the outermost viewport of a rendering scene, for example a browser window or native application window.

Fields

width: f64

Viewport width in pixels.

height: f64

Viewport height in pixels.

major: f64

Larger viewport dimension in pixels.

minor: f64

Smaller viewport dimension in pixels.

aspect: f64

Width divided by height. Returns 0.0 when height is 0.

landscape: bool

True when width is greater than height.

portrait: bool

True when height is greater than width.

square: bool

True when width and height are effectively equal.

Implementations

impl Viewport

pub const SQUARE_EPSILON: f64 = 0.5

Equality tolerance used when classifying square viewports.

pub fn new(width: f64, height: f64) -> Viewport

Build viewport facts from width and height in logical pixels.

Trait Implementations

impl Clone for Viewport

fn clone(&self) -> Viewport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Viewport

impl Debug for Viewport

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

Formats the value using the given formatter.

impl Default for Viewport

fn default() -> Viewport

Returns the “default value” for a type.

impl Interpolatable for Viewport

fn interpolate(&self, other: &Viewport, t: f64) -> Viewport

Interpolates this value toward other at time t on the unit interval.

impl ToPaxValue for Viewport

fn to_pax_value(self) -> PaxValue

Converts this value into a PaxValue.

fn nested_properties(&self) -> Vec<UntypedProperty>

Live properties read when snapshotting a compound value for PAXEL. Adapters observe these as well as the containing property.

fn to_pax_value_in_graph(self) -> PaxValue

where Self: Sized,

Converts against owner-thread graph views, including nested generated property fields. Requires an entered property graph for shared fields. Ordinary Self::to_pax_value reads published value snapshots.
