WebGLRenderingContext.drawingBufferWidth
The read-only WebGLRenderingContext.drawingBufferWidth
property represents the actual width of the current drawing buffer. It should match the
width
attribute of the <canvas>
element associated with
this context, but might differ if the implementation is not able to provide the
requested width.
Syntax
gl.drawingBufferWidth;
Examples
Given this <canvas>
element:
<canvas id="canvas"></canvas>
You can get the width of the drawing buffer with the following lines:
var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
gl.drawingBufferWidth; // 300
