icontact is a highly-configurable Perl script that takes a bunch of image files and creates contact sheets. icontact determines the file format by the file name extension of the input files, and then uses internal tables to look up the commands it needs to execute in order to convert the images to the PPM format. Once they're converted, icontact uses various pbmplus commands to create contact sheets. icontact is particularly useful if you have lots of image files in all sorts of different formats and you want to create an index of all of them without converting them all to a common format first. This package also includes a filter to convert xv's .xvpics files into PPM format.
KVEC is a command line tool that allows you to convert raster graphics to vector graphics. KVEC is designed for 32 bit operating systems and runs on Win32, OS/2, HP-UX, NEXTSTEP, Linux, IRIX, AIX 4.x, Macintosh and BeOS. Docs are available in English and German. The shareware version is available for 30 day trial.
Macfork can be used to both list and extract resources from a Macintosh resource fork under unix. Currently it supports icon families, pict resources and palettes, but the data from any resource may be extracted to a data file. It was written to port Macintosh icons and pictures over to unix, but has many other potential uses.
OIO is a Web-based metadata/data management front-end which is built using Zope and works with Postgresql. No programming is required to build and manage Web-forms or to perform data mining/analysis on the collected data. It is in production at the Harbor/UCLA Medical Center for clinical outcomes management and research data. Forms created with OIO and hosted on any OIO server can be downloaded as XML files. Once downloaded from the "Forms library" and imported into an OIO server, the necessary database tables are automatically recreated and the imported forms become immediately available to the users of that OIO server.
pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for ASCII rather than binary transfer), it has since been extended to check and optionally print almost all the information about a PNG image and to verify that it conforms to the PNG specification. It also includes partial support for MNG animations.
pngquant is a batch conversion utility to quantize and dither truecolor PNG images, especially those with a full alpha channel, down to "RGBA-palette" PNGs (i.e., PLTE + tRNS in PNG parlance). Such images are usually two to four times smaller than the full 32-bit versions, and partial transparency is preserved quite nicely. This makes pngquant especially useful both for Web sites and for PlayStation 2 development, where one of the texture formats is RGBA-palette-based (though not PNG-compressed).
The pnmtopng package contains the official pnmtopng and pngtopnm utilities for use with the rest of the PBMplus/NetPBM suite. They are among the best PNG-supporting applications available, with automatic detection of grayscale or palette images and excellent heuristics for creating the smallest possible PNG images.
