It seems that game developers would like to store assets in binary form in Typed Arrays. How possible/feasible is that? For example, can I say 'take this typed array and interpret it as a JPEG image' ? Another orthogonal question: can one cache on disk (IndexedDB?) the contents of a Typed Array? | It seems that game developers would like to store assets in binary form in Typed Arrays.

''No you can't. You can convert the data into a Blob and get a URL for that, but that involves a memory copy.'' | |||

''Yes, you can store Typed Arrays and ArrayBuffers in IndexedDB just like many other data types.'' | |||
Currently if you want to take data in a Typed Array and display in an <img> or otherwise end up interacting with the DOM, you'll have to copy the data at least once. One solution might be the ability to create a blob-url representing the contents of a Typed Array. | Currently if you want to take data in a Typed Array and display in an <img> or otherwise end up interacting with the DOM, you'll have to copy the data at least once.

''Yes, we should add the ability to get a URL which represents the contents of a TypedArray/ArrayBuffer. Basically that simply means supporting a TypedArray or ArrayBuffer to URL.createObjectURL()'' | |||
