Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

import { gradient } from '@antv/util';
提供以下 Path 工具方法,包含转换、几何计算等。
将 PathArray 转换成字符串形式,不会对原始定义中的命令进行修改:
const str: PathArray = [
['M', 10, 10],
['L', 100, 100],
['l', 10, 10],
['h', 20],
['v', 20],
];
expect(path2String(str)).toEqual('M10 10L100 100l10 10h20v20');
将 PathArray 转换成数组,不会对原始定义中的命令进行修改:
const str = 'M10 10L100 100l10 10h20v20';
expect(path2Array(str)).toEqual([
['M', 10, 10],
['L', 100, 100],
['l', 10, 10],
['h', 20],
['v', 20],
]);
将定义中的相对命令转换成绝对命令,例如:
完整方法签名如下:
path2Absolute(pathInput: string | PathArray): AbsoluteArray;
const str: PathArray = [
['M', 10, 10],
['L', 100, 100],
['l', 10, 10],
['h', 20],
['v', 20],
];
const arr = path2Absolute(str);
expect(arr).toEqual([
['M', 10, 10],
['L', 100, 100],
['L', 110, 110],
['H', 130],
['V', 130],
]);
将部分命令转曲,例如 L / A 转成 C 命令,借助 cubic bezier 易于分割的特性用于实现形变动画。 该方法内部会调用 path2Absolute,因此最终返回的 PathArray 中仅包含 M 和 C 命令。
完整方法签名如下:
path2Curve(pathInput: string | PathArray): CurveArray;
expect(
path2Curve([
['M', 0, 0],
['L', 100, 100],
]),
).toEqual([
['M', 0, 0],
['C', 44.194173824159215, 44.194173824159215, 68.75, 68.75, 100, 100],
]);
复制路径:
const cloned = clonePath(pathInput);
const pathArray: CurveArray = [
['M', 170, 90],
['C', 150, 90, 155, 10, 130, 10],
['C', 105, 10, 110, 90, 90, 90],
['C', 70, 90, 75, 10, 50, 10],
['C', 25, 10, 30, 90, 10, 90],
];
const reversed = reverseCurve(pathArray);
获取几何定义下的包围盒,形如:
export interface PathBBox {
width: number;
height: number;
x: number;
y: number;
x2: number;
y2: number;
cx: number;
cy: number;
cz: number;
}
const bbox = getPathBBox([['M', 0, 0], ['L', 100, 0], ['L', 100, 100], ['L', 0, 100], ['Z']]);
expect(bbox).toEqual({ cx: 50, cy: 50, cz: 150, height: 100, width: 100, x: 0, x2: 100, y: 0, y2: 100 });
获取路径总长度。
const length = getTotalLength([['M', 0, 0], ['L', 100, 0], ['L', 100, 100], ['L', 0, 100], ['Z']]);
expect(length).toEqual(400);
获取路径上从起点出发,到指定距离的点。
const point = getPointAtLength([['M', 0, 0], ['L', 100, 0], ['L', 100, 100], ['L', 0, 100], ['Z']], 0);
expect(point).toEqual({ x: 0, y: 0 });
计算路径包围的面积。内部实现中首先通过 path2Curve 转曲,再计算 cubic curve 面积,详见。
方法签名如下:
function getPathArea(path: PathArray): number;
判断一个点是否在路径上,仅通过几何定义计算,不考虑其他样式属性例如线宽、lineJoin、miter 等。
方法签名如下:
isPointInStroke(pathInput: string | PathArray, point: Point): boolean;
const result = isPointInStroke(segments, { x: 10, y: 10 });
计算两点之间的距离。
方法签名如下:
distanceSquareRoot(a: [number, number], b: [number, number]): number;
将两条路径处理成段数相同,用于形变动画前的分割操作。
const [formattedPath1, formattedPath2] = equalizeSegments(path1, path2);
判断一个点是否在多边形内。多边形形如:
const polygon = [
[0, 0],
[0, 100],
[30, 100],
[30, 0],
];
// [0, 0] 在多边形的边上
isPointInPolygon(polygon, 0, 0); // true
判断两个多边形是否相交:
isPolygonsIntersect(polygon1, polygon2);
