Implementations

impl ImageBitmap

pub fn new( x: f32, y: f32, width: f32, height: f32, data_width: usize, data_height: usize, data: Vec<u8>, ) -> Result<ImageBitmap, JsError>

Creates a new ImageBitmap with the given x, y, width, height, and pixel data.

pub fn data(&self) -> Vec<u8>

Gets the pixel data of the bitmap.

pub fn set_data( &mut self, data_width: f32, data_height: f32, data: Vec<u8>, ) -> Result<(), JsError>

Sets the pixel data of the bitmap.

pub fn default_image_bitmap() -> ImageBitmap

Returns the default ImageBitmap, which is an empty bitmap.

pub fn get_pixel(&self, p: Point2D) -> Color

Gets the color of a Point2D in the bitmap.

pub fn set_pixel(&mut self, p: Point2D, color: &Color)

Sets a pixel color at a Point2D in the bitmap.

pub fn fill( x: f32, y: f32, width: f32, height: f32, data_width: usize, data_height: usize, color: &Color, ) -> ImageBitmap

Gets a bitmap that is filled with a color.

pub fn fill_linear_gradient( x: f32, y: f32, width: f32, height: f32, data_width: usize, data_height: usize, gradient: &LinearGradient, ) -> ImageBitmap

Gets a bitmap that is filled with a linear gradient.

pub fn fill_radial_gradient( x: f32, y: f32, width: f32, height: f32, data_width: usize, data_height: usize, gradient: &RadialGradient, ) -> ImageBitmap

Gets a bitmap that is filled with a radial gradient.

pub fn base64(&self) -> Result<String, String>

pub fn lerp(bitmap1: &ImageBitmap, bitmap2: &ImageBitmap, t: f32) -> ImageBitmap

Linearly interpolates between two ImageBitmaps given a progress value.

Trait Implementations

impl Clone for ImageBitmap

fn clone(&self) -> ImageBitmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageBitmap

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

Formats the value using the given formatter.

impl Default for ImageBitmap

fn default() -> Self

Returns the “default value” for a type.

impl From<ImageBitmap> for JsValue

fn from(value: ImageBitmap) -> Self

Converts to this type from the input type.

impl FromWasmAbi for ImageBitmap

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for ImageBitmap

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for ImageBitmap

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<ImageBitmap>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for ImageBitmap

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for ImageBitmap

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for ImageBitmap

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<ImageBitmap>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for ImageBitmap
