This tutorial will guide you through step by step instructions to install ImageMagick on Ubuntu, covering various methods like APT and compiling from source. We'll also explore basic usage, including image conversion and uninstallation steps, catering to both beginners and advanced users.
ImageMagick is a free and open-source software suite used for creating, editing, and converting digital images. It can read and write in multiple image formats, including JPEG, PNG, TIFF, and GIF, among others. ImageMagick is known for its versatility and ability to perform a wide range of image processing tasks. It's particularly powerful in batch processing, allowing the manipulation of numerous images in a single command.
With ImageMagick, users can resize, rotate, apply various effects, adjust colors, and composite images. It's also capable of converting images from one format to another, making it a handy tool for web development and digital media processing. Its command-line interface is ideal for automating repetitive tasks and integrating with other software applications. ImageMagick's ability to utilize multiple computational threads enhances its performance, especially on systems with multi-core processors.
For more detailed information, you can explore ImageMagick's capabilities on its official website.
1. Steps to Install ImageMagick using the APT Package Manager
Installing ImageMagick on Ubuntu using the APT package manager is a straightforward process. Here's a step-by-step guide along with explanations for each step:
1.1 Open Terminal
First, open your terminal. You can do this by searching for 'Terminal' in your Ubuntu system's applications menu or by pressing
Ctrl + Alt + T.
1.2 Update Package Lists
Before installing new software, it's good practice to update your package lists. This ensures you have the latest information about available packages and their versions. Run the command using sudo privilege:
sudo apt update
This command will ask for your password. Enter it to proceed.
1.3 Install ImageMagick
Now, you're ready to install ImageMagick. Use the command:
sudo apt install imagemagick
This command tells the APT package manager to install the ImageMagick package. sudo is used to run the command with superuser privileges, which are typically required for installing software.
1.4 Verify the Installation
After the installation is complete, it's a good idea to verify that ImageMagick is installed correctly. You can check the installed version of ImageMagick by running:
You may get below error:
Command 'magick' not found, did you mean: command 'magics' from deb magics++ (4.10.1-1) command 'magic' from deb magic (8.3.105+ds.1-1.1) Try: sudo apt install <deb name>
In some versions of ImageMagick, especially older ones like 6.x, the primary command might still be
convert rather than
magick. Try running:
If this works, it means the version installed uses the older command structure.
You can check the installed rpm version using:
dpkg -l | grep -i imagemagick
ii imagemagick 8:188.8.131.52+dfsg-1.3ubuntu0.22.04.3 amd64 image manipulation programs -- binaries ii imagemagick-6-common 8:184.108.40.206+dfsg-1.3ubuntu0.22.04.3 all image manipulation programs -- infrastructure ii imagemagick-6.q16 8:220.127.116.11+dfsg-1.3ubuntu0.22.04.3 amd64 image manipulation programs -- quantum depth Q16
1.5 Uninstall ImageMagick (Optional)
Use the following command to uninstall ImageMagick:
sudo apt remove imagemagick
This command tells APT to remove the ImageMagick package.
sudo is used to run the command with superuser privileges.
If you want to also remove configuration files associated with ImageMagick, use the
purge option instead:
sudo apt purge imagemagick
This command is similar to
remove, but it also deletes the configuration files, which is useful if you don't plan on reinstalling ImageMagick and want to clean up all associated files.
After removing ImageMagick, you can also remove any unused dependencies that were installed with it:
sudo apt autoremove
This step helps to keep your system clean by removing packages that are no longer required.
2. Steps to Install ImageMagick on Ubuntu from Source
Installing ImageMagick from source is ideal if you need the latest version or a specific older release that's not available through the standard package repositories. Here's a detailed guide on how to do this:
2.1 Install Required Dependencies
Before you can compile ImageMagick from source, you need to install some essential build tools and libraries. Open your terminal and run the command:
sudo apt install build-essential libltdl-dev libjpeg-dev libpng-dev libtiff-dev libgif-dev libfreetype6-dev liblcms2-dev libxml2-dev git
This command installs the necessary compilers, libraries, and Git. These are required for building ImageMagick and handling various image formats.
2.2 Clone ImageMagick Repository
Next, clone the ImageMagick repository from GitHub to get the source code. Run the following command to perform git clone:
git clone https://github.com/ImageMagick/ImageMagick.git ImageMagick-Source
This command clones the ImageMagick repository into a folder named
ImageMagick-Source in your current directory.
Change your current directory to the ImageMagick source directory:
2.4 Configure the Build Environment
Before compiling, you need to configure the build environment. Run the command:
This script prepares the ImageMagick source code for compilation on your specific system. It checks for necessary tools and libraries, setting up the correct parameters for the build process.
2.5 Compile ImageMagick
Compile the source code by running:
This command will start the compilation process. It may take some time, depending on your system's performance.
2.6 Install the Compiled Binary
After compilation, install ImageMagick onto your system:
sudo make install
This command installs the compiled binaries and libraries into the appropriate system directories.
2.7 Configure Dynamic Linker Run-Time Bindings
sudo ldconfig /usr/local/lib
This step is essential to ensure your system can find and use the ImageMagick libraries.
2.8 Verify the Installation
Check the installed version of ImageMagick:
This confirms that ImageMagick is successfully installed from the source.
2.9 Uninstall ImageMagick (Optional)
Go to the directory where you initially cloned the ImageMagick source code.
In the source directory, run the following command to uninstall ImageMagick:
sudo make uninstall
This command will use the
Makefile (created during installation) to remove the installed files from your system.
After uninstalling, some files or dependencies might still remain on your system. You can manually delete the source directory if you no longer need it:
cd .. rm -rf ImageMagick-Source
This step removes the source code and any compiled objects in the directory.
If you installed dependencies specifically for ImageMagick and no longer need them, you can remove them using
sudo apt-get autoremove -y
This command removes unused packages that were automatically installed to satisfy dependencies for ImageMagick.
After uninstallation, run:
This will update the dynamic linker run-time bindings.
