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.

API Property Read-only Reference WebGL WebGLRenderingContext

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.

As web applications become more and more powerful, adding features such as audio and video manipulation, access to raw data using WebSockets, and so forth, it has become clear that there are times when it would be helpful for JavaScript code to be able to quickly and easily manipulate raw binary data. In the past, this had to be simulated by treating the raw data as a string and using the charCodeAt() method to read the bytes from the data buffer.
