Sam2p is a UNIX command line utility written in ANSI C++ that converts many raster (bitmap) image formats into Adobe PostScript or PDF files and several other formats. The images are not vectorized. sam2p gives full control to the user to specify standards-compliance, compression, and bit depths. In some cases sam2p can compress an image 100 times smaller than the PostScript output of many other common image converters. Sam2p provides ZIP, RLE and LZW (de)compression filters even on output destined for PostScript Level 1 devices.

The author provides a script bundle, a2ping, that uses sam2p as part of a generic format conversion mechanism.
