dmap2gcode is a depth map image cutting program. A depth map is a greyscale image in which the darkness or lightness of each pixel corresponds to the depth (or height) of the object at each point. dmap2gcode supports various cutter geometries (flat, ball nose, and v-bit), two types of cut entry (straight and arc), a full set of roughing options, and various other settings, all controlled through a graphical user interface. The g-code output from dmap2gcode is compatible with LinuxCNC and Mach3.
geh is a simple command line image viewer with various nice features. It currently supports a slide-show mode displaying multiple images in a row either controlled by a time interval and/or mouse button clicks, and a thumbnail mode creating small thumbnail images and caching them in ~/.thumbnails according to freedesktop.org's thumbnail specification.
image saver is a PHP class which can open an uploaded file image in either JPEG, PNG, or GIF format and resize it to a given width and height. Either the width or height can be set to auto, so it gets adjusted to keep the original image proportion based on the value set for the other dimension. The processed image can be saved to a new file in a given target directory using the JPEG format. The compression quality of the saved image is configurable.
image-deduplication-tool is a script designed to scan specified paths and calculate the DCT hashes of all the images there. It compares the hashes to find closest-looking image pairs, despite various alternations (such as crop, rotation, gamma/color correction, noise, etc.), optionally presenting them in a feh image viewer for the operator to easily compare and remove one of the versions. It uses libpHash to produce and compare perceptual hashes.
jWordConvert is a Java library which can read and render Word documents natively to convert to PDF, to convert to images, or to print the documents automatically. The library is 100% Java, so it can run on any platform which supports Java. It does not use any third party software or native calls, and can be run in a server environment or integrated into a desktop application.
libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors. It uses SIMD instructions (MMX, SSE, SSE2) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4 times as fast as the unmodified version of libjpeg. It also includes a wrapper library for the TurboJPEG API used by VirtualGL and TurboVNC. It was originally based on libjpeg/SIMD but has improved support for Mac OS X, 64-bit platforms, 32-bit and big endian pixel formats (RGBA/BGRA/ABGR/ARGB), accelerated Huffman encoding/decoding, and various other fixes.
