Method 1: Install ImageMagick via APT
Update Debian Before ImageMagick Installation
Before installing ImageMagick on Debian, ensuring your system is current is essential. Updating your system guarantees that it is compatible with ImageMagick and that you have installed the latest security updates.
To update your system, open the terminal and run the following command.
sudo apt update && sudo apt upgradeInstall Required Libraries for ImageMagick
For ImageMagick to work correctly, you need to install specific libraries. Use this command to install them:
sudo apt install libpng-dev libjpeg-dev libtiff-devInstall ImageMagick via APT Command
To install ImageMagick using the APT method, use the following command.
sudo apt install imagemagickAnd that’s it! If you are looking for alternative installation methods, the following section will cover compiling ImageMagick.
Method 2: Install ImageMagick source
If you prefer an alternative installation method, you can clone the ImageMagick GIT repository and compile the application. However, this method is more advanced and may not be suitable for the average user. If you want to utilize the source version and access the latest or a specific older release, follow the steps below.
Ensure Git is Installed on Debian
Before using the alternative installation method, ensure you have Git installed on your system. Check by entering this command in the terminal:
git --versionRun this command to see the installed GIT version on your system. If you don’t have GIT, install it with the command below:
sudo apt install gitClone ImageMagick Git Repository
To clone the repository, navigate where you want to store the cloned repository in the terminal, and then run the following command.
git clone https://github.com/ImageMagick/ImageMagick.gitIf you want, you can specify the location of the cloned repository to “/usr/local/src/ImageMagick” by using the following command.
git clone https://github.com/ImageMagick/ImageMagick.git /usr/local/src/ImageMagickIt is important to note that depending on your GIT or user privilege configuration, you may need to use the sudo command while cloning the repository. For instance, you may encounter permission errors if your current user does not have the required permissions to access the desired location for cloning the repository. In such cases, using the sudo command can help you overcome these issues:
sudo git clone https://github.com/ImageMagick/ImageMagick.git /usr/local/src/ImageMagickNavigate to Cloned ImageMagick Directory
After cloning the ImageMagick repository, navigate to its directory using the following command:
cd ImageMagickAlternatively, if you cloned the repository to “/usr/local/src/ImageMagick,” you can navigate to the directory by running the following command:
cd /usr/local/src/ImageMagickInstall Initial ImageMagick Installation Packages
Before continuing the installation process, you must install the dependencies necessary to compile ImageMagick. These dependencies include various libraries and tools required for the compilation process. You can install them by running the following command in the terminal:
sudo apt install build-essential libltdl-dev libjpeg-dev libpng-dev libtiff-dev libgif-dev libfreetype6-dev liblcms2-dev libxml2-devConfigure Build Script For ImageMagick
After installing the dependencies, run the ./configure command to get ImageMagick ready for compilation:
./configureThis command identifies any missing dependencies or configurations needed to compile ImageMagick. If there’s a missing piece, it will show an error message. If you see an error, install the missing parts or fix the configuration problems before moving on.
Advanced users can enhance ImageMagick by adding the –with-modules option. This option adds more features to ImageMagick:
./configure --with-modules
Compile ImageMagick
Now that you’ve set up the environment, compile ImageMagick with the following command:
make
The make command compiles the ImageMagick source code, creating a usable application. Depending on your system specifications, the compilation process may take several minutes. After the compilation is complete, you can proceed to the next step.
Install Compiled ImageMagick Binary
After compiling the source code, install ImageMagick on your Debian system using the following command:
sudo make install
The installation command will install ImageMagick on your system. After the installation is complete, you can start using ImageMagick.
Run Dynamic Linker Run-Time Command For ImageMagick
After installing ImageMagick, the final step is configuring the dynamic linker run-time bindings. This step is crucial since it ensures your system can locate and use the ImageMagick libraries at run-time.
sudo ldconfig /usr/local/libThe ldconfig command will configure the dynamic linker run-time bindings, making ImageMagick accessible and usable on your system. Once you run this command, you can use ImageMagick without any issues. Failure to perform this step may result in the following error in your terminal:
magick: error while loading shared libraries: libMagickCore-7.Q16HDRI.so.10: cannot open shared object file: No such file or directoryNote: If you upgrade or reinstall ImageMagick in the future, you might need to reconfigure the dynamic linker run-time bindings. In these cases, follow the above steps again.
Verify ImageMagick Installation via source
After successfully installing ImageMagick, you can verify the installation by running the following command:
magick --versionExample output:
Version: ImageMagick 7.1.0-62 (Beta) Q16-HDRI x86_64
Examples of ImageMagick Commands
