初始化后,Fabric.js将我的画布大小更改为300x150

Question

HTML:

  <div class="canvas-wrapper">
    <canvas id="myCanvas"></canvas>
  </div>

CSS

.canvas-wrapper {
    width: 900px;
    min-height: 600px;
 }

 #myCanvas{
     border:1px solid red;
     position: absolute;
     top:22px;
     left:0px;
     height: 100%;
     width: 99%;
 }

JS

var myCanvas = new fabric.Canvas('myCanvas');

我的画布在初始化后调整为300x150,为什么？

Answer 1

在最新版本中,您将需要执行以下操作:

var canvas = new fabric.Canvas('myCanvas');
canvas.setHeight(500);
canvas.setWidth(800);

....你的代码....

canvas.renderAll();

对我来说工作正常..

Answer 2

在初始化canvas时,Fabric会在canvas元素上读取width/height属性,或者在选项中传递宽度/高度.

var myCanvas = new fabric.Canvas('myCanvas', { width: 900, height: 600 });

要么:

<canvas width="900" height="600"></canvas>
...
var myCanvas = new fabric.Canvas('myCanvas');
