Struct gdl::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 height(self) -> u32

pub fn width(self) -> u32

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

pub fn new_from_imgdata(
    &mut self,
    img_data: ImageData,
    width: u32,
    height: u32
) -> PhotonImage

pub fn new_with_background(
    width: u32,
    height: u32,
    background_color: &Rgb
) -> PhotonImage

pub fn new_with_gradient(width: u32, height: u32) -> PhotonImage

pub fn new_socialmedia_graphic(name: &str) -> PhotonImage

Create a new social media graphic. Available types include: linkedin_banner, pinterest, fb_ad, fb_post, instagram_post, twitter_header, twitter_post.

pub fn raw_pix(self) -> Vec<u8>

Trait Implementations

impl From<PhotonImage> for JsValue

fn from(_value: PhotonImage) -> Self

Performs the conversion.

impl Debug for PhotonImage

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

Formats the value using the given formatter.

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 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 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 WasmDescribe for PhotonImage

fn describe()

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
