Visual help, various keyboard layouts, numerous settings and the possibility to create own exercise dictates are easing the learning process. Main features: - Intelligent exercise lessons - Free and own lessons - Scrolling text and virtual keyboard for help - Extensive customization - Performance appraisal - Support of alternate keyboard layouts - Multi platform

Dataplot is a free, public-domain, multi-platform (Unix, Linux, PC-DOS, Windows NT, etc.) software system for scientific visualization, statistical analysis, and non-linear modeling. The target Dataplot user is the researcher and analyst engaged in the characterization, modeling, visualization, analysis, monitoring, and optimization of scientific and engineering processes. The original version was released by James J. Filliben in 1978 with continual enhancements to present. NOTE: This port only includes the command line tool, the website has an experimental GUI tool that uses expect and extensive reference manuals.

dcraw is an ANSI C program that decodes any raw image from any digital camera on any computer running any operating system. It's become a standard tool within and without the Open Source world. It's small (about 3000 lines), portable (standard C libraries only), free (both "gratis" and "libre"), and when used skillfully, produces better-quality output than the tools provided by the camera vendor. This version is modified to add auto-rotate to exported thumbnails, and also add adjustment for camera timezone offset. If your thumbnails appear upside down, set DCRAW_RTC env var.

DjVu is a web-centric format and software platform for distributing documents and images. DjVu was originally developed at AT&T Labs-Research. In March 2000, AT&T sold DjVu to LizardTech Inc. who now distributes Windows/Mac plug-ins, and commercial encoders (mostly on Windows). LizardTech released the reference implementation of DjVu under the GNU GPL in October 2000. DjVuLibre (which means free DjVu), is an enhanced version of that code, maintained by the original inventors of DjVu. It is compatible with version 3.5 of the LizardTech DjVu software suite.

Geeqie is a lightweight Gtk+ based image viewer for Unix operating systems. Main features o EXIF, IPTC and XMP metadata browsing and editing. o Interoperability, easy integration with other software. o geeqie works on files and directories, there is no need to import images. o Fast preview for many raw image formats. o Tools for image comparison, sorting and managing photo collection. History Geeqie has been forked from gqview project, because it was not possible to contact gqview author and the only maintainer. Geeqie projects goal is to move the development forward and also integrate the existing patches.

The JOGL project hosts the development version of the Java (TM) Binding for the OpenGL API (JSR-231), and is designed to provide hardware-supported 3D graphics to applications written in Java. JOGL provides full access to the APIs in the OpenGL 1.3 - 3.0, >= 3.1, ES 1.x and ES 2.x specification as well as nearly all vendor extensions. It integrates with the AWT and Swing widget sets, as well with custom windowing toolkits using the NativeWindow API. It is part of a suite of open-source technologies initiated by the Game Technology Group at Sun Microsystems.

Jhead is a command line driven program for manipulating the non-image parts of Exif flavour JPEG files that most digital cameras produce. It has the following features: - Extracting camera settings from Exif image files - Able to set and/or adjust the Exif time field - Manipulation (extract, replace, regenerate) of Exif integral thumbnails - Transplant Exif image header from one JPEG to another - Edit JPEG comment fields - Automatically rotate images upright (using jpegtran) according to "orientation" tag. - Manage running programs on large batches of Jpegs and restoring Exif header information afterwards. - Display embedded GPS info (if present)

DigiKam is an advanced digital photo management application for KDE, which makes importing and organizing digital photos a "snap". The photos are organized in albums which can be sorted chronologically, by folder layout or by custom collections. An easy-to-use interface is provided that enables you to connect to your camera and preview, download and/or delete your images. Basic auto-transformations can be deployed on the fly during image downloading. Digikam also uses the very flexible Kipi plugin architecture. Install the graphics/kipi-plugins-kde4 port to extend Digikam's features.

Little CMS intends to be a small-footprint color management engine, with special focus on accuracy and performance. It uses the International Color Consortium standard (ICC), which is the modern standard when regarding to color management. The ICC specification is widely used and is referred to in many International and other de-facto standards. It was approved as an International Standard, ISO 15076-1, in 2005. Since version 2.1, Little CMS fully implements ICC specification 4.2 plus all addendums; it fully supports all kind of V2 and V4 profiles, including abstract, devicelink, and named color profiles. Color management refers to techniques that ensure consistent colors while images are transferred from scanners or cameras to monitors and printers.

Anti-Grain Geometry (AGG) is an Open Source, free of charge graphic library, written in industrially standard C++. AGG doesn't depend on any graphic API or technology. Basically, you can think of AGG as of a rendering engine that produces pixel images in memory from some vectorial data. But of course, AGG can do much more than that. The ideas and the philosophy of AGG are: * Anti-Aliasing. * Subpixel Accuracy. * The highest possible quality. * High performance. * Platform independence and compatibility. * Flexibility and extensibility. * Lightweight design. * Reliability and stability (including numerical stability).
