javascript - 拉斐尔-JS : Rect with one round corner

Question

paper.rect(0, 0, settings.width, settings.height, settings.radius);

创建一个带有圆 Angular 的漂亮矩形。是否可以创建一个只有一个圆 Angular 的矩形？

Answer 1

如果你使用 Raphael JS:

Raphael.fn.roundedRectangle = function (x, y, w, h, r1, r2, r3, r4){
  var array = [];
  array = array.concat(["M",x,r1+y, "Q",x,y, x+r1,y]); //A
  array = array.concat(["L",x+w-r2,y, "Q",x+w,y, x+w,y+r2]); //B
  array = array.concat(["L",x+w,y+h-r3, "Q",x+w,y+h, x+w-r3,y+h]); //C
  array = array.concat(["L",x+r4,y+h, "Q",x,y+h, x,y+h-r4, "Z"]); //D

  return this.path(array);
};

只有右上角圆 Angular 的矩形

var paper = Raphael("canvas", 840, 480);
paper.roundedRectangle(10, 10, 80, 80, 0, 20, 0, 0);
