Shapefile C Library is a C library for reading and writing ESRI Shapefiles and their related DBF files. All geometry types are supported, with robust DBF support. Shapelib is widely used for commercial and free projects. Shapelib includes command line utilities for dumping, subsetting, clipping, shifting, scaling, and reprojecting shapefiles.
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.
phpThumb() is a flexible thumbnail generator. The output can be larger or smaller than the source, an entire image or cropped section, with or without configurable borders and/or a background color. The source can be a local file, a remote file, or a database source. GIF reading is supported with or without GD support. BMP reading is supported with or without ImageMagick. Any ImageMagick-supported format can be used as a source if ImageMagick is available. Watermarking, unsharp mask sharpening, and caching are available. EXIF thumbnails can be extracted and/or used for large-source support.
image2mpeg is a tool to convert digital photos (or any other images) into MPEG video streams, with transitions between the images. The photo stream may be accompanied with music (or any other audio stream). The resulting slideshow may be prepared for VCD, SVCD, or DVD playback in stand-alone players, or the MPEG videos may be converted into FLV (Flash Videos). The type of transition can be selected for each image separately from a set of fade, slide, roll, etc.
F-Spot is a personal photo management application for the GNOME desktop. It simplifies digital photography by providing intuitive tools to help you share, touch-up, find, and organize your images. These tools include editing, color adjustments, tags, Photo CD creation, and exporting for upload.
The icoutils are a set of programs for extracting and converting images in Microsoft Windows icon and cursor files. These files usually have the extension .ico or .cur, but they can also be embedded in executables and libraries (.dll-files). Icoutils can also create icon and cursor files.
Renrot renames files according the flexible name template (allowing DateTimeOriginal and FileModifyDate EXIF tags, if they exist; otherwise, the name will be set according to the current timestamp). It can aggregate files according to shooting time period. It can losslessly rotate JPEGs and their thumbnails according to the Orientation EXIF tag or a given angle. It can put commentary into the Commentary and UserComment tags. Personal details can be specified via XMP tags defined in a configuration file.
