But since moving to a new Mac, I decided to re-do my little automations. This will bring up all the parameters that sips accepts.ImageMagick is a robust collection of UNIX tools and libraries offered under a usage license to read, write, and manipulate an image in many image formats (over 89 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. If you’d like to learn about the other features of sips, you can do so by going to Terminal and typing “man sips”.

This command will take the longest dimension, shrink or expand it to, and shrink or expand the other dimension proportionately. If you want the image(s) to be resized such that they fit in a bounding box: Use the command “sips –resampleHeightWidthMax ”. If you want to resample the image(s) to be an exact height and width: Use the command “sips –resampleHeightWidth ”. If you’d like for the image(s) to be uniform height: Use the command “sips –resampleHeight ”, where the variables are as described above. If you want the image(s) to have a specific width: Use the command “sips –resampleWidth ”, where is the width, in pixels, you’d like the image to be, and is the name of your file, a space separated list of files, or *.* to signify all files in the directory.
