Question

Creating a large visualization in HTML.

In Chrome (v. 18), the maximum canvas size is 32,768 pixels high. Is there a way to display a larger canvas?

Where is this limit coming from?

Answer 1

32,768 = 2¹⁵ and 2¹⁵ – 1 = 32,767 is the biggest number a short int can hold.

So Google Chrome probably uses the datatype short int for storing the sizes of a <canvas> element.

If you want to display larger <canvas> elements, you could try to use multiple ones.
You should also consider another implementation technique if you really need ~33k pixels!
