原生微信小程序用path实现画笔 在android正常 ios 少部分手机正常 大部分直接闪退

[nws123045088]

//1.画笔ios add闪退 let brush = null; let lastPoint = undefined; this.canvas.tree.on(DragEvent.START, (e) => { if (this.currentTab !== 4) { return; } lastPoint = undefined; brush = new Path({ zIndex: 99, windingRule: "nonzero", fill: this.brush_color || "rgb(7,193,96)", data: { radius: (this.brush_size || 10) / 2, }, }); this.canvas.tree.add(brush); });

//2.橡皮擦 ios add 画布内容直接不见了 let eraser = null; let lastPoint = undefined; this.canvas.tree.on(DragEvent.START, (e) => { if (this.currentTab !== 3) { return; } lastPoint = undefined; eraser = new Path({ zIndex: 99, windingRule: "nonzero", fill: "rgb(255,255,255,0)", eraser: "path", data: { radius: (this.eraser_size || 10) / 2, }, }); this.canvas.tree.add(eraser); });

收到，谢谢反馈～， path去掉windingRule属性试试，橡皮擦用'path'类型可以： eraser： 'path'

第一个问题 path去掉windingRule属性可以了 第二个问题无效 我排查下

[nws123045088]

eraser = new Path({ zIndex: 99, fill: "rgb(255,255,255,1)", // eraser: "path", data: { radius: (this.eraser_size || 10) / 2, }, }); this.canvas.tree.add(eraser); 加了这个eraser: "path", 画布内容就全部没了
