libjpeg-turbo
SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface. -

pngnq-s9
A modified pngnq: convert png images to 256 colours.
pngnq-s9 is a modified version of pngnq, the neural network colour quantizer for png images. Like pngnq, pngnq-s9 takes a full 32 bit RGBA png image, selects a palette of up to 256 colours, and then redraws the image in 8 bit indexed mode. The resulting image can be up to 70% smaller than the original. pngnq-s9 adds several new options to pngnq including the ability to augment a user-supplied palette, the ability to quantize in the YUV colour space, and the ability to give more or less weight to specific colour components when quantizing. The program also includes a few bug fixes relative to the most recent version of pngnq. The .tar.gz files have been known to compile on Unix type systems, including Cygwin. The only external dependencies are libpng and zlib. For Windows users, we have a 32 bit binary, in pngnq-s9-2.0.2.zip, that should run as is on most modern Windows machines. -

ANSiMat
A graphical, multiplatform ANSI files viewer and converter
ANSiMat is a graphical viewer of ANSI art files. It can also be used to convert ANSI (or plain ASCII) files into regular (BMP, TGA, PCX...) graphic files, or into animations (FLC). Altough not initially designed for this, ANSiMat can be successfully used as an ASCII art viewer, or even simple text files viewer. ANSiMat is available for Linux, Windows and DOS. ANSiMat supports also modem emulation speed, therefore it can be used to display ANSI animations. -

Dr.Oste
Escher's Droste Effect
The Scope is to create a program, which can edit an image with the Droste effect. This program also provides some extra functions like rotating, scaling, converting and filtering. There exist some other programs which also have the some functions, but they are often very expensive and complex to use. For more Information: http://www.josleys.com/article_show.php?id=82 See article: http://www.docma.info/software/artikel/detail/droste-bilder-selbstgemacht.html?L=0cmd%253Dinfomailcmd%253Dinfomail&cHash=57024747077a4e58428fb485285dac18 -
