IPCB_PrimitiveArc.toAsync() method
将图元转换为异步图元
签名
typescript
function toAsync(): IPCB_PrimitiveArc;1
返回值
圆弧线图元对象
示例
javascript
// 1. 生成本次运行专用的坐标,避免与之前保留的测试圆弧重合
const x = 52000 + (Math.floor(Math.random() * 100000));
const y = 2000 + (Math.floor(Math.random() * 100000));
// 2. 创建一段测试圆弧,切换到同步模式,让模式变化可观察
const arc = await eda.pcb_PrimitiveArc.create('', 1, x, y, x + 500, y + 300, 90, 10, 1, false);
arc.toSync();
// 3. 转换为异步图元
const asyncArc = arc.toAsync();
// 4. 异步模式下累计修改并提交
asyncArc.setState_LineWidth(24);
await asyncArc.done();
// 5. 从画布重新读取,确认提交生效(保留现场供观察)
const refetched = await eda.pcb_PrimitiveArc.get(arc.getState_PrimitiveId());
console.log('isAsync after toAsync:', arc.isAsync());
console.log('lineWidth:', 10, '→', refetched.getState_LineWidth());1
