动画GIF的框架只显示增量 [英] Frame of animated GIF only showing deltas

问题描述

我正试图抓住GIF动画的帧。我试过 http://gif-explode.com 和转换+ adjoin loading.gif了ImageMagik中的％d.gif 。不幸的是，在这两种情我猜测动画gif的创建者使用某种压缩，其中每个帧只是前一帧的增量。

I'm trying to grab the frames of an animated gif. I tried http://gif-explode.com and convert +adjoin loading.gif out%d.gif in ImageMagik. Unfortunately in both cases all but the first and last frame are kinda blurred and partially missing. I'm guessing the creator of the animated gif used some sort of compression where each "frame" is just a delta from the previous frame.

如何从这样的动画gif中获取可用的帧？也许在ImageMagik或其他可以做的软件中有一个选项重建。

How can I get useable frames from an animated gif like this? Perhaps there's an option somewhere in ImageMagik or another piece of software that can do the reconstruction.

推荐答案

您可能需要指定coalesce和dispose选项：

You probably need to specify "coalesce" and "dispose" options:

convert -coalesce +adjoin -dispose Previous loading.gif out%d.gif
