Struct ImageNode

pub struct ImageNode {
    pub color: Color,
    pub image: Handle<Image>,
    pub texture_atlas: Option<TextureAtlas>,
    pub flip_x: bool,
    pub flip_y: bool,
    pub rect: Option<Rect>,
    pub image_mode: NodeImageMode,
}

A UI Node that renders an image.

Fields

color: Color

The tint color used to draw the image.

This is multiplied by the color of each pixel in the image. The field value defaults to solid white, which will pass the image through unmodified.

image: Handle<Image>

Handle to the texture.

This defaults to a TRANSPARENT_IMAGE_HANDLE, which points to a fully transparent 1x1 texture.

texture_atlas: Option<TextureAtlas>

The (optional) texture atlas used to render the image.

flip_x: bool

Whether the image should be flipped along its x-axis.

flip_y: bool

Whether the image should be flipped along its y-axis.

rect: Option<Rect>

An optional rectangle representing the region of the image to render, instead of rendering the full image. This is an easy one-off alternative to using a TextureAtlas.

When used with a TextureAtlas, the rect is offset by the atlas’s minimal (top-left) corner position.

image_mode: NodeImageMode

Controls how the image is altered to fit within the layout and how the layout algorithm determines the space to allocate for the image.

Implementations

impl ImageNode

pub fn new(texture: Handle<Image>) -> ImageNode

Create a new ImageNode with the given texture.

Trait Implementations

impl Clone for ImageNode

fn clone(&self) -> ImageNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for ImageNode

where ImageNode: Send + Sync + 'static,

Required Components: Node, ImageNodeSize, ContentSize.

A component’s Required Components are inserted whenever it is inserted. Note that this will also insert the required components of the required components, recursively, in depth-first order.

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

fn register_required_components( requiree: ComponentId, components: &mut Components, storages: &mut Storages, required_components: &mut RequiredComponents, inheritance_depth: u16, )

Registers required components.

fn register_component_hooks(hooks: &mut ComponentHooks)

Called when registering this component, allowing mutable access to its ComponentHooks.

impl Debug for ImageNode

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

Formats the value using the given formatter.

impl Default for ImageNode

fn default() -> ImageNode

A transparent 1x1 image with a solid white tint.

Warning

This will be invisible by default. To set this to a visible image, you need to set the texture field to a valid image handle, or use Handle<Image>’s default 1x1 solid white texture (as is done in ImageNode::solid_color).
