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.
Easy PHP Thumbnail Class can be used to manipulate images and generate thumbnails. It can load images from files and generate thumbnails that can be saved to files or be generated as the current script output. The class can also perform other image manipulation functions such as adding shadows, clipping rounded corners, filters, bilineair image deformations, and more. Over 45 image manipulation functions are available.
epstool is a utility that can create and extract preview images in EPS (Encapsulated PostScript) files, fix bounding boxes, and convert them to bitmaps. It can add EPSI, DOS EPS, or Mac PICT previews, extract PostScript from DOS EPS files, use Ghostscript to create preview bitmaps, and create TIFF, WMF, PICT, or Interchange previews from part of a bitmap created by Ghostscript.
GL2PS is a C library providing high quality vector output for any OpenGL application. It uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non manifold objects. It provides advanced smooth shading and text rendering, culling of invisible primitives, mixed vector/bitmap output, and much more. It can currently create PostScript (PS), Encapsulated PostScript (EPS), Portable Document Format (PDF), and Scalable Vector Graphics (SVG) files, as well as LaTeX files for the text fragments.
"Jpegpixi" is short for "JPEG pixel interpolator". It is a command-line utility which interpolates pixels in JFIF images (commonly refered to as "JPEG images"). This is useful to correct images from a digital camera with CCD defects. Jpegpixi is unique in that it tries to preserve the quality of the JFIF image as much as possible. Most graphics programs decode JFIF images when they are loaded, and re-encode them when they are saved, which results in an overall loss of quality. Jpegpixi, on the other hand, does not decode and re-encode the image, but manipulates the encoded image data, protecting the quality of the image as much as possible.
The XV "jumbo" patches are a pair of aggregate patches against XV 3.10a, which was last released in December 1994. The first jumbo patch incorporates roughly two dozen bugfixes. The second patch encompasses almost as many enhancements, including support for additional image formats like PNG, PhotoCD, and PDF; performance improvements; and new features such as mouse-wheel support, alpha blending against a background color, and improved dithering for 15/16-bit displays. All patches available from the official XV site are included, as well as numerous other patches from around the world.
TransFig is a set of tools for creating TeX documents with graphics which are portable, in the sense that they can be printed in a wide variety of environments. The fig2dev program that is part of TransFig is used by xfig when exporting drawings to the various output formats such as PostScript (and EPS), CGM, JPEG, LaTeX, PNG, and more.
