![]() If you want to both resize and crop the image, the crop is done first.Īs an example… gifsicle -crop 105,0+270x270 -resize 100x100 resize-gif.gif > resize-gif-cropped-resized. For me, this means I put it first in the command so I don’t forget the order. It’s important to note that according to the documentation, “Cropping takes place before any rotation, flipping, resizing, or positioning.” That means if you want to do anything else (like resize, flip, etc.), realize that cropping takes place first. Leaving us with the following: gifsicle -crop 105,0+270x270 resize-gif.gif > resize-gif-cropped.gif We can apply that to our command line input above, adding a 105px offset in the x1 parameter of the crop option. You can find that with this simple formula: ((total longest side) - (total desired length)) / 2 To keep that crop in the center, then, I’ll need 105px offset. The greater than sign tells it to take the original file (i.e., “resize-gif.gif”) and save the cropped version as “resize-gif-cropped.gif” in the same directory.Īlmost right…but it’s offset to the top right-hand corner, so we’re not getting the middle of the gif cropped to a 1:1 square. The -delay 100 option of convert is similar. gifsicle -crop 0,0+270x270 resize-gif.gif > resize-gif-cropped.gif For gifsicle, the -d 100 option causes a delay of 1 second (100 1/100th of a second) between frames, i.e., d -250 causes a 2 1/2 s delay, -d 325 causes a 3 1/4 s delay. ![]() ![]() Next, we provide the cropped dimension: 270x270 as our width and height respectively. For now, let’s just work on getting it to crop the image. 0,0 will start the crop from the top right-hand corner (i.e., x1 = 0 and y1 = 0). The first two tell it where to start the crop from. The crop option takes four parameters: x1, y1 + width x height. Numbers 1, 3, and 4 are self-explanatorry, so let’s focus on #2. sudo apt install gnuplot imagemagick ffmpeg graphviz valgrind gifsicle pstoedit. The crop option (tell it the size, positioning, etc. Note also that there is a specific installation guide contributed by Mac.According to the documentation, we need to provide four things. I am on a M1 mac and it just gives write EPIPE errors. Open Terminal and cd to the directory where your image is found. On this commit 132 you added a ARM version of Gifsicle, but it doesnt work. I want my final gif to be a 1:1 square, so 270x270 is my target size. Here’s a gif of the legendary Jurgen Klopp. This tutorial demonstrates how to install gifsicle on Raspberry Pi. On a Mac, you can install gifsicle using Home-brew with the following command: brew install gifsicle 2. The gifsicle is a command line tool that allows to create, edit, optimize, retrieve information, and perform other operations with GIF images. Here’s a simple step-by-step guide to using it. I used the build and installation instructions from the Gifsicle GitHub repository to create my binary Mac OS executable. I recently needed to crop a gif to a square and found this command-line tool for working with gifs called gifsicle.
