Struct photon::PhotonImage

pub struct PhotonImage { /* fields omitted */ }

Provides the image's height, width, and contains the image's raw pixels. For use when communicating between JS and WASM, and also natively.

Methods

impl PhotonImage

pub fn new(raw_pixels: Vec<u8>, width: u32, height: u32) -> PhotonImage

pub fn new_from_base64(base64: &str) -> PhotonImage

Create a new PhotonImage from a base64 string.

pub fn new_from_byteslice(vec: Vec<u8>) -> PhotonImage

pub fn get_width(&self) -> u32

Get the width of the PhotonImage.

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

pub fn get_height(&self) -> u32

Get the height of the PhotonImage.

pub fn get_image_data(&mut self) -> ImageData

Convert the PhotonImage's raw pixels to JS-compatible ImageData.

pub fn set_imgdata(&mut self, img_data: ImageData)

Convert ImageData to raw pixels, and update the PhotonImage's raw pixels to this.

Trait Implementations

impl From<PhotonImage> for JsValue

fn from(_value: PhotonImage) -> Self

Performs the conversion.

impl From<ImageData> for PhotonImage

Create a new PhotonImage from a raw Vec of u8s representing raw image pixels.

fn from(imgdata: ImageData) -> Self

Performs the conversion.

impl Debug for PhotonImage

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

Formats the value using the given formatter.

impl IntoWasmAbi for PhotonImage

type Abi = u32

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

fn into_abi(self, _extra: &mut dyn Stack) -> u32

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

impl RefFromWasmAbi for PhotonImage

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, PhotonImage>

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, _extra: &mut dyn Stack) -> Self::Anchor

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

impl WasmDescribe for PhotonImage

fn describe()

impl FromWasmAbi for PhotonImage

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, _extra: &mut dyn Stack) -> Self

Recover a Self from Self::Abi.

impl OptionFromWasmAbi for PhotonImage

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 PhotonImage

fn none() -> Self::Abi

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

impl RefMutFromWasmAbi for PhotonImage

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, PhotonImage>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(
    js: Self::Abi,
    _extra: &mut dyn Stack
) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl Serialize for PhotonImage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for PhotonImage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
