放大fabricjs，对象位置(Zooming in fabricjs, object positions)

我有一个问题（我相信它类似于一个calcOffset正在修复）与对象的位置。

我用鼠标滚轮放大了。缩放后，形状将显示在新位置，但无法在这些位置处理。仅在他们的预变焦位置。

jsfiddle的例子

这是我的缩放代码：

function displaywheel(e){ var SCALE_FACTOR = 1.1; var evt=window.event || e var delta=evt.detail? evt.detail*(-120) : evt.wheelDelta var objects = canvas.getObjects(); var dd = 1; if (delta == 120) dd=SCALE_FACTOR; if (delta == -120) dd=1/SCALE_FACTOR; globscale = globscale * dd; for (var i in objects) { objects[i].setCoords; objects[i].scaleX = globscale; objects[i].scaleY = globscale; objects[i].left = objects[i].left * dd; objects[i].top = objects[i].top * dd; objects[i].setCoords; } canvas.renderAll(); canvas.calcOffset(); }

I have a problem ( i believe it is similar to the one calcOffset is fixing) with positions of objects.

I zoom in-out with mouse scroll wheel. After zooming, shapes are displayed at new positions but cannot be handled at these position. Only at their pre-zoom positions.

jsfiddle example

Here is my code for zooming:

function displaywheel(e){ var SCALE_FACTOR = 1.1; var evt=window.event || e var delta=evt.detail? evt.detail*(-120) : evt.wheelDelta var objects = canvas.getObjects(); var dd = 1; if (delta == 120) dd=SCALE_FACTOR; if (delta == -120) dd=1/SCALE_FACTOR; globscale = globscale * dd; for (var i in objects) { objects[i].setCoords; objects[i].scaleX = globscale; objects[i].scaleY = globscale; objects[i].left = objects[i].left * dd; objects[i].top = objects[i].top * dd; objects[i].setCoords; } canvas.renderAll(); canvas.calcOffset(); }
