BINS is a valid HTML 4 photo album generator with support for internationalization, EXIF, and customizable charset encoding, including UTF-8 (Unicode). Albums can contains other sub-albums. The appearance of the album can be fully personalized by using template and configuration parameters. The number and size of scaled pictures can be chosen in pixels or percentage of the original image. Several description fields (date, location, etc.) can be associated with the pictures, and you can add additional description fields. A command line utility or a GTK+ GUI can be used to set or edit description fields. BINS can use the EXIF data structure found in some pictures to automatically fill some fields (most notably, date and time) and to produce a page providing all information available on the picture, as well as the DigiCam settings when the photo was taken. All image meta-data are stored in XML files.
GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like DPX, DICOM, BMP, GIF, JPEG, JPEG-2000, PDF, PNG, PNM, SVG, and TIFF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X.
Ilib is an image manipulation library for developers. It's capable of reading and writing images (PPM/PGM, PNG, JPEG, GIF, XPM, BMP) and many drawing functions including drawing lines and text using any BDF (X11) font. It's great for generating GIFs/PNGs from a CGI or generating graphs. Ilib includes sample applications for generating graphs for HTTP access.log files and QuakeWorld server frag log files and a tool for creating image indices from a group of images.
Prima is an extensible Perl toolkit for multi-platform GUI development. Supported platforms include Linux, Windows NT/9x/2K, OS/2, and UNIX/X11 workstations (FreeBSD, IRIX, SunOS, Solaris, and others). The toolkit contains a rich set of standard widgets and has emphasis on 2D image processing tasks. A Perl program using Prima looks and behaves identically on X, Win32, and OS/2 PM.
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.
a2ping is a Unix command line utility that converts many raster image and vector graphics formats to EPS or PDF and other page description formats. Accepted input file formats are: PS (PostScript), EPS, PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX, and TGA. Accepted output formats are: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM, PS, markedEPS, markedPS, PNG, XWD, BMP, TIFF, JPEG, GIF, and XPM. a2ping delegates the low-level work to Ghostscript (GS), pdftops, and sam2p. Only the first page of PDF and PS files are converted.
album is a free HTML/XHTML photo album and gallery generator that supports themes/skins. You can choose different themes or write your own to get different layouts and styles. It creates all your thumbnails (including directory thumbnails) and descends into directories so you can organize your photos. See the home page for more examples. album is also multi-lingual, with many languages being added all the time. N.B.: The purchase link is provided for donations; the software does not cost anything.
batchgimp is a batch processor for rendering of images. It uses a command-line interface, and supports JPEG, GIF, PNG, and PSD file formats. It accesses the GNU Image Manipulation Program (GIMP) plug-in structure to provide image processing functions. Images are processed in a batch for an entire directory. batchgimp is written in Perl and interfaces with the Scheme scripting engine provided by the GIMP.
