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).

EasyBMP is a cross-platform C++ library for reading and writing Windows bitmap (BMP) files. Designed for ease of use, it requires no installation or external libraries, is small in size, well-documented, and is simple enough for the novice programmer to start in just minutes.

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.

Tumble converts one or more TIFF (B&W only) and
JPEG files into a PDF file. It was developed
primarily for use with scanned images. B&W images
will be encoded with Group 4 fax (T.6) lossless
compression. JPEG images are embedded as-is.
Tumble supports multi-page TIFF files, and can
generate PDF outline entries (bookmarks) based on
the file name and/or the page number.

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.

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.

This is a simple command-line utilitiy to convert
images from TIFF to PNG format. It is primarily
useful in dealing with TIFF images that contain
alpha channels (transparency information), since
the NetPBM suite is (currently) ill-suited for such
conversions. A few test images are included.

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.

darktable is a virtual light table and darkroom for photographers. It manages your digital negatives in a database and lets you view them through a zoomable light table. It also enables you to develop raw images and enhance them.

libgocr is a library to help the creation of OCR
engines. Engines are released as plugins, and can
take advantage of several features that the
library provides. Frontends to the library can be
written for any kind of environment.

QCAD Pro bundles QCAD with additional proprietary tools and plugins, including read and write support for the DWG file format, SVG export, printing a drawing on multiple pages (poster), and support for splines from fit points. QCAD is an application for computer aided drafting in two dimensions (2D). With QCAD, you can create technical drawings such as plans for buildings, interiors, mechanical parts, or schematics and diagrams. QCAD can be easily extended through plugins and its very powerful and complete ECMAScript (JavaScript) interface.

WebPack is a shell script for automatically packing Web sites by shrinking them without affecting their functionality or appearance.
It is also useful for losslessly shrinking image collections and locating corrupt files. It works by stripping unnecessary information and optimizing the compression of images, and by removing comments/whitespace from HTML, using readily-available tools.
