Create Polygon

Signature

function create(
	line: Array<number>,
	color?: string | null,
	fillColor?: string | null,
	lineWidth?: number | null,
	lineType?: ESCH_PrimitiveLineType | null,
): Promise<ISCH_PrimitivePolygon | undefined>;

Parameters

Parameter	Type	Description
line	Array<number>	Coordinate group, a continuous set of lines described by [x1, y1, x2, y2, x3, y3]
color	string | null	(Optional) Color, null indicates the default
fillColor	string | null	(Optional) Fill color. none indicates no fill, null indicates the default
lineWidth	number | null	(Optional) Line width, range 1-10. null indicates the default
lineType	ESCH_PrimitiveLineType | null	(Optional) Line type. null indicates the default

Returns

Promise<ISCH_PrimitivePolygon | undefined>

Polygon primitive object

Example

// 1. 生成随机起点坐标，避免与画布上已有的多边形重合（SCH 坐标单位 10mil）
const x = 2000 + Math.floor(Math.random() * 8000);
const y = 2000 + Math.floor(Math.random() * 8000);

// 2. 创建一个 4 顶点矩形多边形：顶点依次为左下、右下、右上、左上，红色虚线边线、黄色填充、线宽 6
const line = [x, y, x + 400, y, x + 400, y + 300, x, y + 300];
const polygon = await eda.sch_PrimitivePolygon.create(line, '#FF0000', '#FFFF00', 6, 1);

// 3. 创建类保留现场，不删除图元
