IPCB_PrimitiveRegion.done() 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.

Apply the changes to the primitives to the canvas

Signature

function done(): Promise<IPCB_PrimitiveRegion>;

Returns

Promise<IPCB_PrimitiveRegion>

Region primitive object

Example

// 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（1）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. 异步模式下把区域挪到底层铜层（此时画布还没变）
const asyncRegion = region.toAsync();
asyncRegion.setState_Layer(2);
await asyncRegion.done();

// 4. 从画布重新读取，确认修改已生效（保留现场供观察）
const refetched = await eda.pcb_PrimitiveRegion.get(region.getState_PrimitiveId());

console.log('layer:', before, '→', refetched.getState_Layer());
