Kabeja is a Java library for parsing CAD data (i.e. Autodesk's DXF format) and converting to SVG (dxf2svg). You can use Kabeja from the command line or embed it into your application. It includes a plain DXF2SVGViewer and integration into the Cocoon XML Web development framework and the Inkscape SVG editor.
LILO-Splash-Screen Script-Fu is a script for the GIMP which helps you create fancy splash screens for use with LILO (and the boot-logo patch). It converts an RGB image to an indexed one, selecting appropriate colors for the image and a special region of interest (the current selection) where the boot menu shall reside. This is done by first duplicating the selection and its inversion, converting both to indexed images, then adding a modified color palette (ADD/SUB) required for the menu bar, and finally recombining all palette colors into a single 256 color palette.
LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, though some of the drawbacks of dcraw have been eliminated. The users of the library are provided with an API to be used when writing their software programs.
LinPHA is an easy-to-use, multilingual, flexible photo/image archive/album/gallery written in PHP. It uses an SQL database (MySQL/PostgreSQL/SQLite) to store information about your pictures. It comes with an HTML-based installer, so you don't need experience in setting up SQL databases. Thumbnails are created as needed and stored in the SQL DB. It features complete user management, top ten statistics, hidden albums, different themes, slideshow, filemanager, uploader, watermarks, benchmark, printing, and more.
Moonshiner is a graphical frontend for Ghostscript's PostScript-to-PDF converter. While Ghostscript (and its wrapper ps2pdf) is a very powerful instrument, it is quite challenging to use its parameters on the command line, especially if you often change the settings as to what kind of color conversion, image resampling, etc. you want Ghostscript to perform. While the author has never used Adobe's Distiller, and thus cannot really compare the two, Moonshiner (as the name suggests) is supposed to be a work-alike for the Linux world (at least GUI-wise, as the actual work is of course done by Ghostscript).
Motiontrack is a set of tools that detects motion between two images. It is able to successfully distinguish random flicker from real object movement by applying a set of filters to the images, and can optionally ignore given colors and/or image regions. The roadmap provides for being able to identify objects by pattern detection and AI routines. Currently, this part is able to turn line-art images into ASCII-art text and auto-align images which are slightly staggered or contorted. This might also be useful to correct the perspective of image sources from different 3D angles.
Mrwtoppm provides a command line utility and a Gimp plugin for processing RAW image files from Minolta's DiMAGE 5 and 7 series digital cameras. The programs decode Minolta's RAW format, perform Bayer pattern interpolation, and color space conversion. The programs also perform tone control and sharpening in CIELab color space. Utilities for displaying much of the additional data stored in the RAW file are also included.
