animate Command in Linux
animate is a Linux command that you can use to create animations from images or image sequences on any X server. This command is used to display a series of images, you only have to provide a set of input images in JPEG, GIFs, and PNGs and the animate command will display them as an animation. It supports several options to control animation speed, looping and other parameters.

How to Install animate Command in Linux?
The animate command is a part of the ImageMagick suite that provides powerful tools for image manipulation and conversion. The ImageMagick tool is available in the official Linux repository and can be installed from the built-in Linux package manager.
For Debian-based systems like Ubuntu, and Debian, the ImageMagick utility can be installed from the apt package manager using the following command −
sudo apt install imagemagick
The Red HAT and CentOS users can install ImageMagick tools on their system from the below-given command −
sudo yum install imagemagick
On Arch Linux, you can install the ImageMagick utility through the below-given command −
sudo pacman -S imagemagick
Once, you installed the ImageMagick utility, confirm whether animate command is working by running the following command −
animate --version
Syntax for animate Command in Linux
The basic syntax to use the animate command on Linux is given below −
animate [options] input-file
Here, the keyword animate will invoke the animate command on Linux. The [options] are flags or parameters that will customize the behavior of the animation. The input-file is the image file or a sequence of image files that you want to animate on your Linux system.

Image Format
Typically, a file’s image format is identified by its unique magic number (file signature). To explicitly specify an image format, prefix the filename with the format name followed by a colon (e.g., ps:image) or provide the format explicitly.
Examples of animate Command in Linux
Let’s discuss a few examples of animate command on Linux −
- Animate an Image
- Animate a Directory of Images
- Control the Animation Speed
- Resize Image in the Animation
- Animate Images with a Specific Background Color
- Animate Images with a Specific Geometry
- Animate Images with Progress Monitoring
- Animate Images with Transparency
Animate an Image
One of the basic operations of the animate command is to simply animate an image. You can do this by using the animate command with the name of the image file, including the format. For example, let’s animate an image file image.png on Linux by using the following command −
animate image.png
Animate a Directory of Images
Besides animating a single image, you can also use the animate command to simultaneously animate multiple images on your Linux system. For that purpose, you must use the wild card * option with the image format you want to animate. For example, if you want to animate png images on your Linux system, you can use the following command −
animate *.png
Note − Ensure multiple png files are there at the same location. It will animate only those images that are placed at the current location.
Control the Animation Speed
You can also control the animation speed of your image to make the animation more enjoyable or easier to understand for viewers. You can do this using the animate command followed by the -delay option, your desired delay value and the image name with the format.
For example, let’s add a delay between frames in hundredths of a second for the image named image.png using the below-given command −
animate -delay 20 image.png
Resize Image in the Animation
To optimize performance and increase the image loading time, you can also resize your image in the animation using the animate command. For that purpose, use the -resize option with the resize percentage followed by the image name you want to animate. As an example, let’s resize (reduce) the image named image.png to 50% on Linux from the following command −
animate -resize 50% image.png
Animate Images with a Specific Background Color
You can also animate the images with a specific background color on your Linux system with the animate command. This requires the use of -background option followed by the background color and the name of the image file you want to animate. For example, let’s animate the image named image.png with a specific background color ‘skyblue’ using the following command −
animate -background 'skyblue' image.png
Animate Images with a Specific Geometry
To ensure your image fits precisely within a particular area of the screen, you can animate it with a specific geometry using the animate command. For that, you must use the -geometry option followed by the animation window and desired coordinates positions, and image name you want to animate. Let’s animate the image name image.png with a specific geometry with the size of the animation window to 800x600 and positions it at coordinates (150,250) using the following command −
animate -geometry 800x600+150+250 image.png
Animate Images with Progress Monitoring
For immediate feedback and troubleshooting purposes, you can animate the image with the progress monitoring using the animate command with -monitor option. We will take the same image file named image.png and monitor progress on the terminal with the -monitor option −
animate -monitor image.png
Animate Images with Transparency
To provide a visual appeal and professional finish to your image, you can also animate an image with transparency using the -matte option with the animate command. The following example will animate the image named image.png with transparency on your Linux system −
animate -matte image.png
That’s how you can animate your images with the animate command on your Linux system.
Conclusion
animate is a powerful command that you can use by installing the ImageMagick utility on your Linux systems. There are tons of options you can use with the animate command to customize your image according to your desired need.
We have explored 8 different examples of animate command on Linux to help you better understand how to use different options of this command. You can explore more options according to your need, animate your image and give it a professional look right from the Linux terminal.
