	startX: number,
	startY: number,
	width?: number,
	height?: number,
	rotation?: number,
	mirror?: boolean,
	fileName?: string,
): Promise<ISCH_PrimitiveObject | undefined>;

Parameters

Parameter	Type	Description
content	File | string	Object content
startX	number	Start point coordinates X
startY	number	Start point coordinates Y
width	number	(Optional) Width

rotation	number	(Optional) Rotation angle
mirror	boolean	(Optional) Whether it is mirrored
fileName	string	(Optional) File name

Returns

Promise<ISCH_PrimitiveObject | undefined>

Example

// 1. 生成随机放置坐标，避免与画布上已有的内嵌对象重合（SCH 坐标单位 10mil）
const x = 2000 + Math.floor(Math.random() * 8000);
const y = 2000 + Math.floor(Math.random() * 8000);

// 2. 准备 4x4 像素 PNG 的 data URI（content 实测也接受裸 base64，data URI 带格式头更易读）
const png = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAQAAAAECAIAAAAmkwkpAAAAEElEQVR4nGP4z8AARwzEcQCukw/x0F8jngAAAABJRU5ErkJggg==';

// 3. 在起点（x, y）放置图片：宽 400、高 300，不旋转、不镜像，文件名 logo.png
const obj = await eda.sch_PrimitiveObject.create(png, x, y, 400, 300, 0, false, 'logo.png');

// 4. 创建类保留现场，不删除图元（getState_Content 返回数据内容，用长度表示）
console.log('primitiveId:', obj.getState_PrimitiveId());
console.log('primitiveType:', obj.getState_PrimitiveType());
console.log('startX:', obj.getState_StartX(), 'startY:', obj.getState_StartY());
console.log('width:', obj.getState_Width(), 'height:', obj.getState_Height());
console.log('fileName:', obj.getState_FileName());
console.log('content length:', obj.getState_Content().length);
