Open Source C Image Converters

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.

GraphicsMagick provides a set of commandline tools and programming APIs for manipulating, editing, and converting raster and vector images. It is derived from ImageMagick, with the objective of providing better stability and performance than ImageMagick while retaining the original MIT/X11 license.

OpenGLide is a Glide to OpenGL wrapper. It emulates a Voodoo board so you can run old Windows Glide games by translating Glide calls into OpenGL. The CVS code moved to https://github.com/fcbarros/openglide.

In the tradition of the Unix computing philosophy, here is yet another operator that does one simple task, namely the creation of an AVI MJPEG file given a list of JPEG/JFIF files.

Foresight is a LGPLed wrapper that currently brings together the Intel IPL, Intel OpenCV, ImageMagick, and the Matrox MIL. The ultimate goal is to provide a standard interface for any number of acquisition and image processing libraries.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

QuickASCII is a movie player that works in your command line, converting movies into ASCII on the fly.

Yina displays videos after a conversion to ascii art, it can streams from youtube or local file. yina 0.1 version actually on dev, it's an alpha prototype.

Drip is a DVD transcoder for Unix. Main target platform is Linux with a Gnome environment. Drip is a full featured application, with support for subtitles, audio and angle selection and complete control of what part of the DVD should be encoded. Plugin f

freeOpenML is a free (OSI) implementation of OpenML for POSIX (4, semaphores, shared memory, threads, realtime, MessageQueues...) OS this include linux >2.6.6 As developers might know OpenML is only a OpenStandard it's sdk is avaible under NDA and pro

mjpgTools is an encapsulation of the JPeGlib and MJPeGtools and several other useful routines into 1 win32-DLL

mkthumb is a unix tool (console based) used to generate image thumbnails in an automatic way. For each file specified, it creates a new file which contains the thumbnail image. Parameters such as the thumbnail size and path location can be specified.
