Struct avrox_display::gfx::primitives::Overlay

pub struct Overlay<LAYER1, LAYER2>
where
    LAYER1: Renderable,
    LAYER2: Renderable,
    LAYER2::PIXEL: Into<LAYER1::PIXEL>,
{ /* private fields */ }

Layers one object on top of the other; if the top object can’t render a requested pixel, then the bottom layer is asked to do so instead

Implementations

impl<LAYER1, LAYER2> Overlay<LAYER1, LAYER2>

where LAYER1: Renderable, LAYER2: Renderable, LAYER2::PIXEL: Into<LAYER1::PIXEL>,

pub fn new(top: LAYER1, bottom: LAYER2) -> Self

Trait Implementations

impl<LAYER1, LAYER2> Renderable for Overlay<LAYER1, LAYER2>

where LAYER1: Renderable, LAYER2: Renderable, LAYER2::PIXEL: Into<LAYER1::PIXEL>,

type PIXEL = <LAYER1 as Renderable>::PIXEL

fn get_pixel_at<P: RenderPlane>(&self, coord: Point) -> GfxResult<Self::PIXEL>

Return the value of the pixel at the given X-Y coordinate

fn has_changes<P: RenderPlane>(&self) -> bool

Indicate if any of the content of this renderable has (or may have) changed.

fn get_change_area<P: RenderPlane>(&self) -> GfxResult<Option<Area>>

Return the area of this renderable that has (or may have) changed.

fn get_dimensions<P: RenderPlane>(&self) -> GfxResult<(XCoord, YCoord)>

Return the dimensions of this primitive. Other container types may use this to aid in optimisation or layout.
