  • What is the action you are supposed to do?

  • How many images you are working on?

  • What is the size of the image you are working on?

The number of images is another important factor. Working on a directory with hundreds of images is obviously different from handling a single file and needs much more memory.

The third factor is the size of the image you are working with. Bigger images need larger amount of memory. I installed and tested ImageMagick on several machines with various free resources and based on my experiments allocating 100 MB of disk space for swap memory on a computer with 128 MB of RAM will...
