我有一个包含多个对象的组。如果该组未旋转。一切看起来都很好,控制也和预期的一样。
然而,当我采用完全相同的组并在渲染之前以编程方式设置旋转角度时,我的控件坐标等于边界矩形,而不再是组坐标。
我在这里创建了一个简化版本的问题:http://jsfiddle.net/schacki/avd6sjps/2/
fabric.Object.prototype.originX = "center";
fabric.Object.prototype.originY = "center";
// init canvas
var canvas = window._canvas = new fabric.Canvas('c');
var angle = 20;
// Group 1: no rotation
var left1 = new fabric.Rect({
width: 50,
height: 50,
fill: 'red',
left:75,
top: 75,
originX: "center",
originY: "center"
});
var middle1 = new fabric.Rect({
radius: 50,
fill: 'green',
width: 300,
height: 100,
left: 200,
top: 100,
originX: "center",
originY: "center"
});
var right1 = new fabric.Rect({
width: 50,
height: 50,
fill: 'blue',
left:325,
top: 125,
originX: "center",
originY: "center"
});
var group1 = new fabric.Group([middle1, left1, right1],{angle: 45});
// Group 1: no rotation
var left2 = new fabric.Rect({
angle: 45,
width: 50,
height: 50,
fill: 'red',
left:75+54,
top: 275-80,
originX: "center",
originY: "center"
});
var middle2 = new fabric.Rect({
angle: 45,
radius: 50,
fill: 'green',
width: 300,
height: 100,
left: 200,
top: 300,
originX: "center",
originY: "center"
});
var right2 = new fabric.Rect({
angle: 45,
width: 50,
height: 50,
fill: 'blue',
left:325-54,
top: 325+80,
originX: "center",
originY: "center"
});
var group2 = new fabric.Group([middle2, left2, right2]);
canvas.add(group1);
canvas.add(group2);
canvas.setActiveObject(group1);
canvas.setActiveObject(group2);
基本上我想让第2组中的控件看起来像第1组的控件。谢谢
