Struct DrawParam 

pub struct DrawParam {
    pub src: Rect,
    pub color: Color,
    pub trans: Transform,
}

Fields

src: Rect

A portion of the drawable to clip, as a fraction of the whole image. Defaults to the whole image (0,0 to 1,1) if omitted.

color: Color

A color to draw the target with. Default: white.

trans: Transform

Where to put the Drawable.

Implementations

impl DrawParam

pub fn new() -> Self

Create a new DrawParam with default values.

pub fn src(self, src: Rect) -> Self

Set the source rect

pub fn dest<P>(self, dest_: P) -> Self

where P: Into<Point2<f32>>,

Set the dest point

pub fn color(self, color: Color) -> Self

Set the drawable color. This will be blended with whatever color the drawn object already is.

pub fn rotation(self, rot: f32) -> Self

Set the rotation of the drawable.

pub fn scale<V>(self, scale_: V) -> Self

where V: Into<Vector2<f32>>,

Set the scaling factors of the drawable.

pub fn offset<P>(self, offset_: P) -> Self

where P: Into<Point2<f32>>,

Set the transformation offset of the drawable.

pub fn transform<M>(self, transform: M) -> Self

where M: Into<ColumnMatrix4<f32>>,

Set the transformation matrix of the drawable.

Trait Implementations

impl Clone for DrawParam

fn clone(&self) -> DrawParam

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawParam

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

Formats the value using the given formatter.

impl Default for DrawParam

fn default() -> Self

Returns the “default value” for a type.

impl<P> From<(P,)> for DrawParam

where P: Into<Point2<f32>>,

Create a DrawParam from a location. Note that this takes a single-element tuple. It’s a little weird but keeps the trait implementations from clashing.

fn from(location: (P,)) -> Self

Converts to this type from the input type.

impl<P> From<(P, Color)> for DrawParam

where P: Into<Point2<f32>>,

Create a DrawParam from a location and color

fn from((location, color): (P, Color)) -> Self

Converts to this type from the input type.

impl<P> From<(P, f32, Color)> for DrawParam

where P: Into<Point2<f32>>,

Create a DrawParam from a location, rotation and color

fn from((location, rotation, color): (P, f32, Color)) -> Self

Converts to this type from the input type.

impl<P> From<(P, f32, P, Color)> for DrawParam

where P: Into<Point2<f32>>,

Create a DrawParam from a location, rotation, offset and color

fn from((location, rotation, offset, color): (P, f32, P, Color)) -> Self

Converts to this type from the input type.

impl<P, V> From<(P, f32, P, V, Color)> for DrawParam

where P: Into<Point2<f32>>, V: Into<Vector2<f32>>,

Create a DrawParam from a location, rotation, offset, scale and color

fn from( (location, rotation, offset, scale, color): (P, f32, P, V, Color), ) -> Self

Converts to this type from the input type.

impl PartialEq for DrawParam

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
