Command line image resize8/25/2023 You can do this in your shell/perl script. Use the convert program to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample. If for some reason you still need to know the longer side, I usually use the identity function to retrieve image information first. If, for example, you wanted each image to have a maximal width of 800, then you can just make the height portion of the scale option an unreasonable high number for you images.Īs you can see, by setting the height to a number larger than a feasible proportional height, you get all images sized to 200 pixels in width regardless of orientation. If this is what you are looking for, then you don't need to know which size is longer. Note that if you use an option such as resize 800x800, it will resize images as follows: Provide the desired sizes and I'll paste an example in here. Give me an example of two different images in a folder, including width and height. Use multi-threading for encoding, if possible. Note: scaling is applied after cropping.-mt. If either (but not both) of the width or height parameters is 0, the value will be calculated preserving the aspect-ratio. maxdepth 0 -iname "*.jpg" -print0 | xargs -0 mogrify -path /tmp/thumbs -thumbnail 120x120 -quality 75 -format png Resize the source to a rectangle with size width x height. Upgrade if you need to use a different directory as well as a different image format for your output.įind. *Before IM v6.3.4-3 the "-format" and "-path" settings were mutually exclusive.

NOTE! Mogrify is a dangerous command because it operates on the original files! Test your commands on COPIES of your files.įind. Then, it is time to convert the temporary gif to the final resized image through the following command syntax: convert -size orig-size-of-input-gif temporary-image. maxdepth 0 -iname "*.jpg" -print0 | xargs -0 -I -l is deprecated in preference for -L 1.įind. As is well known by many, to change the size of an image in Gnu / Linux we can use GIMP, Shutter or ImageMagick in the terminal.Use -maxdepth 0 to avoid descending into subdirectories.Use -print0 (and -0) to avoid problems with filenames containing Carriage Returns.
