The Npic library and tools

Copyright (c) 2003-2010 by Edouard Thiel <Edouard.Thiel@lif.univ-mrs.fr>

The Npic library provides types and functions in C language to memorize and manipulate bitmap images of dimension 2 to 6, different pixel types, external border, linear access and cartesian coordinates access.

The Npic tools are a set of command-line utilities that give access to the library functions, like drawing in images, computing distance transforms and medial axis, converting file formats, and more. Some computations are multi-threaded with OpenMP.

A multi-dimensional compressed file-format (NPZ) is proposed by Npic. This format is also accepted by: QVox V.2. Other files format are accepted by Npic: PAN in 2D/3D/3D+t, VOL in 3D, PNM/PBM/PGM/PPM in 2D, possibly compressed on fly with gzip, bzip2 or p7zip.
