PDL::IO::Pic

Description

PDL::IO::Pic is a image I/O for PDL. Image I/O for PDL based on the netpbm package. This package implements I/O for a number of popular image formats by exploiting the xxxtopnm and pnmtoxxx converters from the netpbm package (which is based on the original pbmplus by Jef Poskanzer). Netpbm is available at ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/ Pbmplus (on which netpbm is based) might work as well, I havent tried it. If you want to read/write JPEG images you additionally need the two converters cjpeg/djpeg which come with the libjpeg distribution (the "official" archive site for this software is ftp://ftp.uu.net/graphics/jpeg). Image I/O for all formats is established by reading and writing only the PNM format directly while the netpbm standalone apps take care of the necessary conversions. In accordance with netpbm parlance PNM stands here for portable any map meaning any of the PBM/PGM/PPM formats. As it appeared to be a reasonable place this package also contains the routine wmpeg to write mpeg movies from PDLs representing image stacks (the image stack is first written as a sequence of PPM images into some temporary directory). For this to work you additionally need the program mpeg_encode from the Berkeley multimedia package. You find mpeg_encode at ftp://mm-ftp.cs.berkeley.edu/pub/multimedia/mpeg/encode (they even have binaries for a number of platforms)..
