Open Source Cygwin Graphics Software

VirtualGL redirects 3D commands from a Unix/Linux OpenGL application onto a server-side GPU and converts the rendered 3D images into a video stream with which remote clients can interact to view and control the 3D application in real time.

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.

Perl library and command-line application for reading, writing and editing meta information (EXIF, IPTC, XMP, and more) in a wide variety of file formats (JPEG, TIFF, PNG, PDF, RAW, and more).

FastPhotoTagger tries to be the fastest way to set the metadata in your photos. Add, change, delete, and search the metadata fields of your choice. FastPhotoTagger excels when you have lots of files and lots of metadata. With FastPhotoTagger, you can - Set multiple images to have the same tags - Set individual images to have unique tags - Display all the metadata in an image - Compare and edit all the metadata in several images - Work with your favorite metadata fields: EXIF, XMP, IPTC, etc. - Define hierarchical keywords - View images and slideshows that display tags as captions - Create and search a metadata database FastPhotoTagger has versions for PC and Android. FastPhotoTagger uses ExifTool to read & write metadata, HyperSQL to manage its database, dcraw to display DNG & RAW, and ImageMagick to display TIFF. WEBP, & HEIC.

FTGL is a free cross-platform Open Source C++ library that uses Freetype2 to simplify rendering fonts in OpenGL applications. FTGL supports bitmaps, pixmaps, texture maps, outlines, polygon mesh, and extruded polygon rendering modes.

pfstools - a set of programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. pfscalibration - photometric calibration of cameras and HDR images from multiple exposures. pfstmo - tone mapping operators.

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.

High Dynamic Range Visual Difference Predictor (HDR VDP) is a perceptual metric that can predict whether differences between two images are visible to the human observer or not.

Freestyle is a software for Non-Photorealistic Line Drawing rendering from 3D scenes. Inspired by Pixar's Renderman, it is designed as a programmable interface to allow maximum control over the style of the output image.

A UNIX/X11 circuit drawing application with schematic capture. Features user-definable parts libraries and fully hierarchical SPICE netlist generation.

Generate 3d steroscopic image easily just by giving left and right image. Input image can be jpg, png, bmp, etc. Output format is uncompressed bitmap image.

Y.A.P.R.M. is a free-as-in-freedom modeller to graphicaly design 3d scenes and generate POV-Ray-files for them. Appart from the basic POV-Ray objects which can be used in CSG operations it supports spline based objects. Furthermore a vast amount of 3d-files can be imported and used with Y.A.P.R.M.

A new improved version of Virtual Camera 2.

This software can generate EAN13, EAN8, 2/5 industrial, 2/5 interleaved and QR code (output is in PNG of JPG). It is supported batch generating from XML. Result is saved to PDF file.

A Software for determing codes for hex and all the properties of color. This software uses vb 13 as a base language and .Net Framework 4.5.This software is stable but recommendation and issues are always welcome

The ObjectVolume program calculates the volume, surface area and centroid of a closed triangular mesh represented in an object file (.obj). The process goes through the list of triangles that make up the surface and, for each triangle, forms a tetrahedron with an external point. The program uses the origin (0,0,0). The volume of the tetrahedron is then calculated. Tetrahedrons with back facing triangles are added and those with forward facing triangles are subtracted yielding the object volume. A detailed description of the process is presented in the ObjectVolumeTutorial.doc document as well as program logic and results. A key component in the program is a subroutine that calculates the volume of a tetrahedron. Four sets of equations were tested and to my surprise all four produced similar results in accuracy and timing.

Reduce your digital image size without loosing quality and size!!!

kradview is a viewer of images obtained for some different sources: X-ray, NMR and all DICOM-compatible imaging devices. Its aim is to be a complete platform for medical imaging and image processing.

Requires: .NET 4.5 The Flower of Life Generator is capable of generating large, intricate flower of life diagrams. The diagrams can be saved as editable flower files for later, or directly exported as images.

Fourier is a portable image processing and analysis library written in ANSI C. It implements operations such as color space conversions, noise removal, enhancement, morphology, edge detection, thresholding, segmentation, and visual feature extraction

OpenArena is a 3d game creation engine. It is a rendering system that can be used for more than just games but it is targeted at games. The basic use being create some game media textures models maps and config files for physics and rules.

Introduction: aPhoto is a batch, intuitive and portable program that helps you to make text(eg. Copyright Notice) and image(eg. Logo) watermarks for the photos, and save the result photos to JPG, PNG, GIF, or BMP file formats. aPhoto is a lightweight application whose purpose is to help users embed text or image watermarks on their favorite pictures. This is a portable program, so it is important to mention that it doesn't leave any traces in the Windows Registry. You can copy it on any USB flash drive or other devices, and take it with you whenever you to need to create watermarks on the breeze, without having to go through installation steps. Since this is a Java-based utility, you should make sure you have previously installed the working environment on the computer, otherwise you cannot run the tool. aPhoto sports a clean and intuitive layout that lets you import photos using the built-in browse function.
