How to Crop an Image from the Command Line on Linux Mint 21
Cropping photos is a typical operation that many individuals must complete for a variety of reasons. This article demonstrates how to crop an image from the command line in Linux Mint 21.
Step 1: Install ImageMagick
Installation of the ImageMagick software package is the initial step. ImageMagick is a free and open-source image viewing, conversion, and editing software suite. ImageMagick may be installed with the following command:
sudo apt-get install imagemagick
Step 2: Navigate to the Directory Containing the Image
After installing ImageMagick, use the cd command to navigate to the directory containing the image you wish to crop. If your image is situated in the Pictures directory, for instance, you can use the following command:
Step 3: Crop the Image
After you are in the image’s directory, you can crop the image using the convert command, which is part of the ImageMagick package. This is the fundamental syntax for cropping an image:
convert [input file] -crop [width]x[height]+[x]+[y] [output file]
Here is a breakdown of the command:
[input file]– The name of the input file, including the file extension.
[width]– The width of the cropped image, in pixels.
[height]– The height of the cropped image, in pixels.
[x]– The x-coordinate of the top-left corner of the cropped area.
[y]– The y-coordinate of the top-left corner of the cropped area.
[output file]– The name of the output file, including the file extension.
For instance, you can use the following command to crop a picture named “example.png” to a width of 500 pixels, a height of 300 pixels, and starting at the coordinates (100, 100):
convert example.png -crop 500x300+100+100 cropped.png
The resulting cropped image will be saved as “cropped.png” in the same directory as the original image.
Tips for Optimizing Image Cropping on Linux Mint 21
Here are some suggestions for streamlining the image cropping process on Linux Mint 21:
1. Preview the Image before Cropping
It is advisable to preview an image before cropping it to ensure that you are cropping the correct area. The display command, which is included in the ImageMagick package, can be used to preview an image. For instance, the following command can be used to preview an image named “example.png”:
This will open the image in your Linux Mint 21 system’s default image viewer.
2. Use the Aspect Ratio Option
When cropping an image, it is often essential to maintain the original image’s aspect ratio. You can use the convert command’s -aspect option to preserve the aspect ratio of a cropped image. For instance, you can use the following command to crop an image to a width of 500 pixels while retaining the aspect ratio:
convert example.png -crop 500x+0+0 -aspect 500x cropped.png
This will crop the image to 500 pixels wide while preserving its aspect ratio. The final image will be saved in the same directory as the original image as “cropped.png.”
3. Use the Resize Option
Frequently, it is important to resize an image to a specified size before cropping it. You can use the convert command’s -resize option to resize the image before cropping it. For instance, you may use the following command to resize a picture named “example.png” to a width of 1000 pixels before cropping it to a width of 500 pixels:
convert example.png -resize 1000x -crop 500x+0+0 resized_cropped.png
This will resize the image to 1000 pixels wide and then crop it to 500 pixels wide. The final image will be saved in the same directory as the original image as “resized cropped.png.”
