Any successful image processing activity in ImageMagick needs enough swap memory and RAM. The amount of required memory depends on three factors:
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?
As mentioned in the previous chapter, there are many actions that can be performed with ImageMagick. Some of them like resizing images need less system resources as compared to ones like working with PDF formats.
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...
