expo-pixi-drgsr v1.4.0

expo-pixi

Tools to use Pixi.js in Expo!

To get started: yarn add expo-pixi in your Expo project and import it with import ExpoPixi from 'expo-pixi';.

Functions

ExpoPixi.application(props): PIXI.Application

A helper function to create a PIXI.Application from a WebGL context. EXGL knows to end a frame when the function: endFrameEXP is called on the GL context.

context is the only required prop.

ExpoPixi.textureAsync(resource: any): Promise

ExpoPixi.spriteAsync(resource: any): Promise

a helper function to resolve the asset passed in. textureAsync accepts:

• localUri: string | ex: "file://some/path/image.png"
• static resource: number | ex: require('./image.png')
• remote url: string | ex: "https://www.something.com/image.png"
• asset-library: string (iOS CameraRoll) | ex: "asset-library://some/path/image.png"
• Expo Asset: Expo.Asset | learn more: https://docs.expo.io/versions/latest/guides/assets.html

You cannot send in relative string paths as Metro Bundler looks for static resources.

ExpoPixi.sprite({ localUri: string, width: number, height: number }): PIXI.Sprite

ExpoPixi.texture({ localUri: string, width: number, height: number }): PIXI.Texture

Pixi.js does a type check so we wrap our asset in a HTMLImageElement shim.

ExpoPixi.Sketch

A component used for drawing smooth signatures and sketches.

See the sketch example on how to save the images!

Notice: the edges and ends are not rounded as this is not supported in PIXI yet: Issue

Props

ExpoPixi.FilterImage

A Image component that uses PIXI.Filter
