Command-Line Image Processing with ImageMagick

There are times being stuck with a load of images that need to be cropped, resized or converted, but doing this by hand in an image editor is tedious work. One tool I commonly use in these desperate situations is ImageMagick, which is a powerful tool when automating raster and vector image processing. Here I’ll introduce a few common commands I had to look up multiple times.
