1、使用离屏 定义如下 const canvas = wx.createOffscreenCanvas({ type: '2d', width: canvasWidth, height: canvasHeight }) const canvasCtx = canvas.getContext('2d') 2、顺利生成 let res = canvasCtx.createImageData(canvasWidth,canvasHeight) （一点也不顺利的 结果 ） res 的 值{data: Uint8ClampedArray(1216500), width: 375, height: 811, dataUnion: Uint8ClampedArray(1216500)} 3、问题1 我要怎么用这个数据呢？ 4、也无法存下图片，这一步报错 wx.canvasToTempFilePath({ x: 0, y: 0, width: canvasWidth, height: canvasHeight, destWidth: canvasWidth, destHeight: canvasHeight, canvas: canvas, success(res) { console.log(res.tempFilePath) } }) wx.canvasToTempFilePath 这一步的报错信息如下 VM282 WAService.js:2 TypeError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(CSSImageValue or HTMLImageElement or SVGImageElement or HTMLVideoElement or HTMLCanvasElement or ImageBitmap or OffscreenCanvas)'

域名是配置了的 jpg类型的图片可以下载，一换成webp就报错getImageInfo:fail invalid webp图片没有问题，放在浏览器里面也可以下载打开  wx.getImageInfo({       src:"https://jiandao-yibu-test.oss-cn-chengdu.aliyuncs.com/corse/Mis9OU64rdNF4f8f4d4b705aecac09d6685e4f08157c.webp",       // src: "https://jiandao-yibu-test.oss-cn-chengdu.aliyuncs.com/corse/K9sZ6SreM7hI23feba53a29bb6b6979fe227d5394367.jpg",       success(res) {         console.log('success-------', res)       },       fail(e) {         console.log('fail-------', e)       }     })
