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.
