How to extract gif image to multiple png/jpg images?

[agriz]

I want to extract gif image and then i want to join them using ffmpeg.
How do i extract those layers from gif?

Code: Select all

convert img.gif img/xx_%05d.png

Is it right?
It is not clearly extracting images from gif.

That should extract the images. What happens instead? What error messages do you get? Do you get any images?

(For input to ffmpeg, each image must represent the entire frame, rather than merely a difference. So you may need other IM options, such as "-coalesce").

I have some strange outputs.
The first frame of the gif is extracted correctly.
But the second and other frames are having only the animated part. The original image around / behind (or wherever) is missing.

But i tried to use the identify function from imagemagick. Which game me the output the of the scenes in the gif image.
If the scenes are 10, then i tried the following which game me the correct extracted images.

Code: Select all

convert img.gif[11] img/xx_%05d.png

The images are extracted like this

xx_00001-0.png
xx_00001-1.png
...

(however there was some error thrown. But the images are extracted)

The GIF is "optimized" so only the aniimated part is present. When you show it on a display, each partial frame is written over what's
already on the screen. Use

Code: Select all

convert -coalesce img.gif[11] img/xx_%05d.png

to "Fully define the look of each frame of an GIF animation sequence".

But i tried to use the identify function from imagemagick. Which game me the output the of the scenes in the gif image.

convert img.gif[11] img/xx_%05d.png

xx_00001-0.png
xx_00001-1.png
...

I guess you need to "escape" the percent-sign if you are running on some operating system where the "%" means something to the shell.
How to "escape" a symbol depends on your system. It could be "%", '%', \%, or maybe something else.
