The read-only WebGLRenderingContext.drawingBufferHeight
property represents the actual height of the current drawing buffer. It should match the height
attribute of the <canvas>
element associated with this context, but might differ if the implementation is not able to provide the requested height.
Syntax
gl.drawingBufferHeight;
Examples
Given this <canvas>
element:
<canvas id="canvas"></canvas>
You can get the height of the drawing buffer with the following lines:
var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
gl.drawingBufferHeight; // 150
