Struct Layer 

pub struct Layer<IMG> { /* private fields */ }

Represents a layer of the canvas. Layers are stacked on top of each other to make a final image, blending colors with transparency. Layers can be moved up or down relative to each other, can be made invisible or have a level of transparency (opacity).

Implementations

impl<IMG: Bitmap> Layer<IMG>

pub fn new(size: Size<i32>) -> Self

Create a new layer with a specified size

pub fn canvas(&self) -> &Canvas<IMG>

Get the Canvas of this layer

pub fn canvas_mut(&mut self) -> &mut Canvas<IMG>

Get a mutable reference to the Canvas of this layer

pub fn visible(&self) -> bool

Whether this layer is visible

pub fn opacity(&self) -> u8

Get the opacity level (alpha) of this layer, a value from 0-255

pub fn take_img(&mut self) -> IMG

Take the image of this layer’s Canvas, leaving a dummy empty one in its place

pub fn resize(&mut self, size: Size<i32>) -> IMG

Resize this layer, returning the previous image (the image before the resizing)

pub fn set_visibility(&mut self, visible: bool)

Set whether this layer is visible

pub fn set_opacity(&mut self, opacity: u8)

Set the opacity of this layer
