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.
WebGLRenderingContext.drawingBufferHeight
Value
A number.
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
