使用JavaScript从gif获取帧数和帧之间的延迟

Question

I am trying to know the frame count and delay between frames of a gif usign javascript , Without actualy parsing the gif with canvas, possibly from the its header .

After long search in Google, which return no results, I've tried to understand it from a gif parsign libraries such as 'giflib' with no success of understanding.

At the end I want to do it using simple code I cant include library to the existed code , An y other parsing tools wont be used at all , I just look for this specific parameters

Thanks.

How about jsgif ?

It allows you to parse an animated gif file with JavaScript and add some controls to it. With some modification you can change this to a counter of how many frames your gif file has?
