Create a spites file from multiple gifs

Hi guys. I want to create sprites file for my site from multiple gifs. Here's my stackoverflow question.
So lets imagine I have 3 gif files: Image+Image+Image.
I wanna create single image sprites file. Basically I can do it with

Code: Select all

montage ./*.gif  -geometry +0+0 -alpha On -background "rgba(0, 0, 0, 0.0)" -quality 100
and get such result:
Image
So here I have 2 issues:
  • I want to have single gif file per row or column. This I can easily create animation. With montage I can only specify fixed `tile` count, but gif files have different parts count. For example yellow smile has 36 images, green one 28 and red one only 6. I think I resolve this issues creating png sprite per gif file with `x1 tile` and then concatenate them into a single file. But I'd like to now if it's possible with single operation
  • The most important to me. As you can see smileys parts are not fully drawn. The only changed part is drawn. I want to have a full image on each partial. As I already found it's related to disposal layers method.
    I tried created sprite with all montage -list dispose parameters
    • montage -dispose None
    • montage -dispose background
    • montage -dispose None
    • montage -dispose Previous
    The result always stills the same, like parameters doesn't affect at all. It's the image I attached above. I also tried to convert gif first. Well for some images it works. For example :
    • Image + "montage" = Image, but Image +"convert -layers dispose" + "montage" = Image . Which is perfectly ok!
    • The same iteration above applying to another smile lacks frames
      • Image + "montage" =Image.
      • Image + "convert -layers dispose" = Image.
      • Image+"convert -layers dispose" + "montage" =Image

      Code: Select all

Please always provide the version of ImageMagick you're using and let us know what OS you're working on. Those can be very important to steering you toward the correct solution.

It's a bit difficult to understand exactly what you're trying to do here, but this command (I'm using ImageMagick 6.9.3-9 Q16 x64 on Windows 7 64) will make a single PNG image with three horizontal rows of individual images, each row made from one of your yellow, green, or red original GIF files...

Code: Select all

convert -background none ^
   ( smilie_yellow.gif -coalesce +append ) ^
   ( smilie_green.gif -coalesce +append ) ^
   ( smilie_red.gif -coalesce +append ) ^
   -append -flatten 3_smilies.png
If you're on a *nix system you'll probably need to make those continued-line characters into backslashes "\" instead of carets "^", and you'll need to escape all the parentheses with backslashes like "\(" and "\)".

Each row of the finished PNG file has all its parts divided into the same width, but the parts in all three rows are different widths than those in the other rows, so whatever sort of operation you use to break them back apart will have to use different calculations for each color of smilie.

Oh man, thank you so much, that's exactly what I've been looking for. A gif per line and each frame of gif is a full image.

The question is really hard to explain though, I will end up with something like this but with multiple gifs for 1 png.
