RenderCan插件简介

RenderCan插件描述

A simple way to recd a canvas. It will recd any canvas elements on the page as well as any svg animations. When finished, all the frames will be downloaded into a single tar file. You can then use these raw images in any way you want. F example, to convert to a movie you can use something like: `ffmpeg r 60 i canvas%09d.png out.webm`. The extension will temparily override Date  perfmance.now so that time moves at 60fps constantly so that the output images are always consistent. Note: this can look like your project is animating slowly, but that is just so that the output frames are 60fps. Final note, frames are output on a requestAnimationFrame.
