PCB_Document.convertDataOriginToCanvasOrigin() method

Input a data coordinate and return the canvas coordinate corresponding to that coordinate

Signature

function convertDataOriginToCanvasOrigin(x: number, y: number): Promise<{ x: number; y: number }>;

Parameters

Parameter	Type	Description
x	number	Data origin X
y	number	Data origin Y

Returns

Promise<{ x: number; y: number }>

Canvas origin coordinate

Remarks

The coordinates displayed on the EasyEDA front end are all relative to the canvas origin; the EasyEDA API uses the data origin; when creating a PCB, the default canvas origin equals the data origin

Example

// 1. 创建测试 PCB 并打开（文档级 API 作用于当前激活的 PCB）
const pcbUuid = await eda.dmt_Pcb.createPcb();
await new Promise(r => setTimeout(r, 1500));
await eda.dmt_EditorControl.openDocument(pcbUuid);
await new Promise(r => setTimeout(r, 1000));

// 2. 换算数据坐标 (300, 400)。新建 PCB 画布原点与数据原点重合，换算值不变
const before = await eda.pcb_Document.convertDataOriginToCanvasOrigin(300, 400);
console.log('before:', JSON.stringify(before));

// 3. 设置画布原点偏移后再换算同一坐标，观察映射随之变化
await eda.pcb_Document.setCanvasOrigin(50, 100);
const after = await eda.pcb_Document.convertDataOriginToCanvasOrigin(300, 400);
console.log('after:', JSON.stringify(after));

// 4. 清理测试 PCB（偏移随文档一起删除）
await eda.dmt_Pcb.deletePcb(pcbUuid);
