netpbm-free is Debian's fork of netpbm that was
designed with security of code, reliability of
interfaces, and freedom of software in mind. It is a
suite of over 200 different programs from different
authors, and is itself a fork of pbmplus. The suite
supports almost every graphic format (including JPEG,
PNG, BMP, ICO), and can create, change, crop, rotate,
and transform in and between these formats.
