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.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

From 3D model, goki check matches 2D image.

This is a set of command line tools that are useful for editing image metadata. Currently it contains the following tools: * image2xml * xml2image * mpo2jps Currently supported file formats are: * jpeg (jfif or exif) * mpo * jps. These tools are mostly useful for editing metadata. image2xml can also generate a .h header file with the offsets of different metadata in the binary file. This could be used in small devices that generate jpeg/mpo/jps images where metadata construction from scratch is not required.

svgconv is a content tool to convert SVG paths into a C format that can be easily used with OpenVG.
