What we have shown is just a sample of all available options.As krlmlr notes in their answer, jpegtran (installed on Ubuntu with sudo apt install libjpeg-turbo-progs) is available for lossless rotation, but because it outputs to standard output, the command to use it would be something like this: $ for img in *.jpg do jpegtran -rotate 90 -copy all $img > rotated-$ | cut -d\. There are many customizations available for image rotation and resizing. You can customize the above commands as per your requirement. Mogrify /home/ubuntu/image.jpg -rotate 90 -resize 200x100 /tmp/image.jpg #resize image to 200x100 and rotate 90 degrees using convert Mogrify -rotate 90 -resize 200x100 /home/ubuntu/image.jpg #resize image to 200x100 and rotate 90 degrees using mogrify You can even combine image rotation and resizing a single command, by using both options together, as shown in the following commands.
#Imagemagick rotate how to#
We have also learnt how to resize & rotate one or more images. In this article, we have learnt how to resize and rotate images using ImageMagick library’s convert and mogrify commands. Mogrify -resize 200x100 /home/ubuntu/*.jpg # rotate all files Here is the command to use mogrify to resize all jpg images in /home/ubuntu to 200px x 100px. If you are fine with in-place editing of images, you can use mogrify command. for szFile in /home/ubuntu/*.jpgĬonvert "$szFile" -resize 200x100 /tmp/"$(basename "$szFile")" jpg files in /home/ubuntu and resize them to 200×100. If you want to resize multiple images using convert command, run a for loop through them and run convert command on each of them.
To rotate 45 degrees counter-clockwise and overwrite the input file: mogrify -rotate '-45' foo.jpg. To rotate 90 degrees clockwise and write output as new file: convert -rotate '90' in.jpg out.jpg. $ mogrify -resize 200x100! /home/ubuntu/image.png Rotating images from the shell is easy with ImageMagick tools. $ convert /home/ubuntu/image.png -resize 200x100! /home/ubuntu/new-image.png If you don’t want to retain aspect ratio, add bang(!) at the end of image dimensions. In the above commands, the convert and mogrify commands will retain the original aspect ratio while resizing images. $ mogrify -resize 200x100 /home/ubuntu/image.png $ convert /home/ubuntu/image.png -resize 200x100 /home/ubuntu/new-image.png Let us say you want to resize file /home/ubuntu/image.png to 200px x 100px then here is the command to do it using convert and mogrify. $ convert source_file -resize dimensions destination_file Here is the syntax to resize images using convert and mogrify commands. You can also use convert and mogrify commands to resize images, using -resize option. With convert, you can save it as a different file. The main difference between convert and mogrify commands is that mogrify rotates an image in place, that is, the original image will be replaced with new image in file. Mogrify -rotate 90 /home/ubuntu/*.jpg # rotate all files Mogrify -rotate 90 /home/ubuntu/image.jpg Mogrify -rotate -90 /home/ubuntu/*.jpg # rotate all files Mogrify -rotate -90 /home/ubuntu/image.jpg # rotate 1 file
#Imagemagick rotate code#
This way you can automate image rotation of one or more images, by embedding the above code in your shell script.Īlternatively, you can also use mogrify the same way as convert, except that it will be a lossy conversion. for szFile in /home/ubuntu/*.jpgĬonvert "$szFile" -rotate 90 /tmp/"$(basename "$szFile")" If you want to convert all jpg files in /home/ubuntu, run a loop through these files and call convert command on each file separately. $ convert /home/ubuntu/image.jpg -rotate -90 /tmp/image.jpg If you want to rotate an image clockwise, use -90 instead of 90 in the above command. You can use the above convert command on almost all image formats. The above command will rotate image.jpg and save a copy in /tmp/image.jpg. $ convert /home/ubuntu/image.jpg -rotate 90 /tmp/image.jpg Let us say you want to rotate file image.jpg by 90 degrees (counterclockwise). The simplest way to do this is using convert function. There are several ways to rotate images in Linux using ImageMagick.
