This photo gallery software makes web albums of your digital images. JAlbum aims to be the easiest to use and most powerful tool in this category - and free! JAlbum is written after numerous disappointments with existing photo gallery software. With JAlbum you have full control of the look of the generated album, not just color theme and basic layout, still making an album is just a matter of drag and drop + a button click if you prefer to use one of the many existing looks. JAlbum will process your images, make index pages and slide show pages and even upload the final album to the Internet for your friends to see. No extra software is needed to view the albums, -just your web browser. Unlike "server side" album scripts, JAlbum albums can be served from a plain web server without scripting support. You can also share your albums on CD-ROM.

This is a drop-in replacement for the graphics/jpeg library. It does not include libturbojpeg.so (see graphics/libjpeg-turbo). libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal. libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but the TigerVNC and VirtualGL projects made numerous enhancements to the codec, including improved support for Mac OS X, 64-bit support, support for 32-bit and big endian pixel formats (RGBA, ABGR, etc.), accelerated Huffman encoding/decoding, and various bug fixes. The goal was to produce a fully open source codec that could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL and TurboVNC. libjpeg-turbo generally achieves 80-120% of the performance of TurboJPEG/IPP. It is faster in some areas but slower in others.

# The Color Transformation Language # The Color Transformation Language, or CTL, is a programming language for digital color management. Digital color management requires translating digital images between different representations or color spaces. For example, the pixels in an image may encode the colors that should be seen when the image is displayed on a video monitor. Printing this image on paper, or recording it on motion picture film requires transforming the pixels to an appropriate representation: Video, inks on paper and film all have different color gamuts and dynamic ranges. Color mixing is additive for video, but subtractive for inks and film. Video and film typically use three color channels, while four or more inks are used for printing on paper. A color management system must transform each pixel in the original image to corresponding amounts of ink or film density values.

Geomview and OOGL are part of an ongoing effort at the Geometry Center to provide interactive 3D graphics software which is particularly appropriate for displaying the kinds of objects and doing the kinds of operations of interest in mathematics research and education. You can compute an OOGL data file of a mathematical object that would be difficult or impossible to build a model of in the real world. In geomview, besides examining an object in ordinary Euclidean 3-space, you can look at objects in hyperbolic 3-space and Euclidean 4-space. The hyperbolic model is the projective one, where geodesics are straight lines and isometries are represented as 4x4 projective matrices. While geomview is tailored for mathematical visualization, it is written to be extensible and can serve as a general-purpose tool. Its functionality can be extended in an almost unlimited fashion by external modules.

Copperspice is a C++ library derived from the existing Qt 4.8 framework. The goal was to change the core design of the libraries, leveraging template functionality and C++11 capabilities. The redesign allowed the Qt Meta-Object Compiler (moc) system to be completely removed. Moc is a code generator and does not support many aspects of C++ including templates, complex data types, static type checking, and relies heavily on string comparisons. Removing moc improves runtime performance, reduces the complexity of the build process, and allows more issues to be detected at compile time. Key features: * Qt Meta-Object Compiler (moc) is obsolete * Written in C++11 * Library links directory to any standard C++ application * A template class can inherit from QObject * Copperspice includes several Qt5 classes

The Mesh Viewer is an easy to use lightweight application to display triangular meshes from a variety of file formats. It uses the OpenGL API to render the models. The program was born under the need for quickly displaying reconstructed triangulated meshes. The Mesh Viewer based on an idea and an early elementary implementation from Craig Robertson. The current version was developed by Helmut Cantzler. Triangular meshes can be displayed texture mapped (optional with bilinear filtering), solid or as a skeleton (full or just the front lines). The surface normals of the triangles can be displayed optionally. Features (from a different data file) like edges and points can be displayed into the mesh. Loaded models can be rotated, translated and scaled (all done with the mouse). The model is lighted by multiple light sources. Viewpoints can be saved. Screenshots of the model can be taken (as BMP, JPEG, PNG and so on).

OpenJUMP is an open source GIS software written in Java. It is based on JUMP GIS by Vivid Solutions. It's features include: * It is a Vector GIS that can read rasters as well. * OpenJUMP is known to work on Windows, Linux and Mac platforms, but should work on any operating system that runs Java 1.5 or later. * It is not just another free demo viewer, but you can edit, save, analyze etc. with JUMP / OpenJUMP. * It works, even with medium size datasets, and with professional touch. * It provides a GIS API with a flexible plugin structure, so that new features are relatively easy to develope around the sound mapping platform. * It utilises standards like GML, WMS and WFS. * It is already translated in English, Finnish, French, German, Italian, Portugese and Spanish. The translation in other languages is in progress. Extensions and plugins can be found at

Ever wish you add information to your photos like a caption, the place you took it, the date, and perhaps even keywords and categories? You already can. The International Press Telecommunications Council (IPTC) defines a format for exchanging meta-information in news content, and that includes photographs. You can embed all kinds of information in your images. The trick is putting it to use. That's where this IPTCInfo Perl module comes into play. You can embed information using many programs, including Adobe Photoshop, and IPTCInfo will let your web server -- and other automated server programs -- pull it back out. You can use the information directly in Perl programs, export it to XML, or even export SQL statements ready to be fed into a database.

SANE ("Scanner Access Now Easy") is a universal scanner interface. The value of such a universal interface is that it allows writing just one driver per image acquisition device rather than one driver for each device and application. So, if you have three applications and four devices, traditionally you'd have had to write 12 different programs. With SANE, this number is reduced to seven: the three applications plus the four drivers. Of course, the savings get even bigger as more and more drivers and/or applications are added. sane-backends contains documentation, several backends, scanimage command line frontend, and networking support. For other/graphical frontends take a look at sane-frontends and/or xsane.

A program to allow the user to view a complete directory of X bitmaps and X pixmaps all in one go, and to perform user defined actions on these images. If you don't think this is usful, you have never dealt with a directory of small icon images.
