Feature request OffScreen Canvas #104

Closed kasperkamperman closed 4 years ago

kasperkamperman commented 4 years ago

You use canvas for most operations. Did you consider supporting OffScreen canvas: https://developers.google.com/web/updates/2018/08/offscreen-canvas

It's a Chrome only technology, so maybe it's too much fuss to implement (especially because it would also involve a web-worker then):

Thanks for the suggestion. In most cases, there is only a single drawImage call (which has to be an OnScreen canvas so it can be displayed), however I've added support to use an OffScreen canvas where applicable.
