On some platforms, ImageMagick automatically processes these extensions: `.gz` for Zip compression, `.Z` for Unix compression, `.bz2` for block compression, and `.pgp` for PGP encryption. For example, a PNM image called `image.pnm.gz` is automatically uncompressed with the `gzip` program and the image is subsequently read.

Image manipulation software that works like magic.
