Get points on the arc

[matinzd]

I wanted to know if it's possible to to get the coordinates of the points on the arc. Similar to cubic bezier formula?

Ended up using Skia.ContourMeasureIter to calculate the total length and getting the position of the points on the path.

import type { SkPath } from '@shopify/react-native-skia';
import { Skia } from '@shopify/react-native-skia';

export const getPathContour = (path: SkPath) => {
  'worklet';
  const it = Skia.ContourMeasureIter(path, false, 1);
  return it.next();
};

export const getPathLength = (path: SkPath) => {
  'worklet';
  return getPathContour(path).length();
};

/**
 * Get the point of a path at a given length
 * @param path {SkPath} Skia path to be processed
 * @param length {number} Length of the path to get the point from. Value between 0 and 1
 * @returns
 */
export const getPointOfPathAtLength = (path: SkPath, length: number) => {
  'worklet';
  const contour = getPathContour(path);
  const totalLength = contour.length();
  return contour.getPosTan(totalLength * length)[0];
};
