WebGLRenderingContext: drawingBufferWidth property
Available in workers
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.
Value
A number.
Examples
Given this <canvas> element:
<canvas id="canvas"></canvas>
You can get the width of the drawing buffer with the following lines:
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
gl.drawingBufferWidth; // 300
