IPCB_PrimitiveRegion.reset() method
This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.
Reset the async primitive to the current canvas state
Signature
typescript
function reset(): Promise<IPCB_PrimitiveRegion>;1
Returns
Promise<IPCB_PrimitiveRegion>
Region primitive object
Example
javascript
// 1. 生成本次运行专用的坐标,避免与之前保留的测试图元重合
const x = 2000 + Math.floor(Math.random() * 100000);
const y = 2000 + Math.floor(Math.random() * 100000);
// 2. 创建一个顶层铜层的矩形区域
const polygon = eda.pcb_MathPolygon.createPolygon(['R', x, y, 500, 300, 0, 0]);
const region = await eda.pcb_PrimitiveRegion.create(1, polygon);
const before = region.getState_Layer();
// 3. 异步模式下把层改到底层(2),随后反悔
const asyncRegion = region.toAsync();
asyncRegion.setState_Layer(2);
// 4. reset 丢弃未提交的修改(保留现场供观察)
await asyncRegion.reset();
// 5. 从画布重新读取,确认层没有变
const refetched = await eda.pcb_PrimitiveRegion.get(region.getState_PrimitiveId());
console.log('layer:', before, '→', refetched.getState_Layer());1
