If you're a performance nut, you'll want to optimize the GIF as well! You can use any number of GIFs and the outcome is a solid, single GIF. Gifsicle -crop 370x275 -colors 256 -merge first.gif second.gif -o merged.gif Editing individual frames in optimized GIFs is dangerous without -unoptimize frames following the changed frame could be corrupted by the change. The following command will achieve the desired result: gifsicle -b -unoptimize -O2 anim.gif -replace 1 x.gif -unoptimize is used since anim.gif was optimized in the last step. So let's assume you have GIFs of the same size and you're ready to create your merged GIF. To work around that error, you'll want to add -colors 256 parameter when merge the GIFs. you don't crop), the earlier GIF may show up behind subsequent GIFs, making for a sloppy image.Īdditionally you may receive a gifsicle: warning: too many colors, using local colormaps error.
Gifsicle is good at creating and manipulating GIF animations.
The \1\2\3\4\5\6 option, for example, tells gifsicle to interlace its inputs: gifsicle -i < pic.gif > interlaced-pic.gif.If you have GIFs of different sizes (i.e. Gifsicle normally processes input GIF files according to its command line options and writes the result to the standard output. Gifsicle has a -crop option which crops images to a given size: The top GIF manipulation library for years has been Gifsicle, so I looked toward Gifsicle for merging multiple animated GIF images.īefore you merge your GIFs, however, you'll want to ensure that they're the same size.
The command line process works in some fairly obvious ways.
This puts the software really into a class of its own. Creating a GIF from a video is fairly simple at this point, as I pointed out in Convert Video to GIF or GIF to Video, but working with multiple GIFs is something many people would like to do. Gifsicle is a little different because rather than being the usual GUI-based GIF editor, this tool is actually a command-line tool instead.
