Graphics

2D game development library. Gosu provides simple and game-friendly interfaces to 2D graphics and text (accelerated by 3D hardware), sound samples and music as well as keyboard, mouse and gamepad/joystick input.

Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it: * Uses degrees. * Draws in quadrant 1 (0-90 degrees). * Right hand rule: 0 degrees is east, 90 is north, etc. These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation.

This gem allows you to render SVG directly into a PDF using the 'prawn' gem. Since PDF is vector-based, you'll get nice scaled graphics if you use SVG instead of an image.

RinRuby is a Ruby library that integrates the R interpreter in Ruby, making R's statistical routines and graphics available within Ruby. The library consists of a single Ruby script that is simple to install and does not require any special compilation or installation of R. Since the library is 100% pure Ruby, it works on a variety of operating systems, Ruby implementations, and versions of R. RinRuby's methods are simple, making for readable code. The {website [rinruby.ddahl.org]}[http://rinruby.ddahl.org] describes RinRuby usage, provides comprehensive documentation, gives several examples, and discusses RinRuby's implementation.

Glimmer DSL for SWT (JRuby Desktop Development Cross-Platform Native GUI Framework) is a native-GUI cross-platform desktop development library written in JRuby, an OS-threaded faster JVM version of Ruby. It includes SWT 4.30 (released on December 1, 2023). Glimmer's main innovation is a declarative Ruby DSL that enables productive and efficient authoring of professional-grade desktop applications by relying on the robust Eclipse SWT library, with the familiar native look, feel, and behavior of GUI on Mac, Windows, and Linux. Glimmer additionally innovates by having built-in data-binding support, which greatly facilitates synchronizing the GUI with domain models, thus achieving true decoupling of object oriented components and enabling developers to solve business problems (test-first) without worrying about GUI concerns, or alternatively drive development GUI-first, and then write clean business models (test-first) afterwards. Not only does Glimmer provide a large set of GUI widgets, but it also supports drawing Canvas Graphics like Shapes and Animations. To get started quickly, Glimmer offers scaffolding options for Apps, Gems, and Custom Widgets. Glimmer also includes native-executable packaging support, sorely lacking in other libraries, thus enabling the delivery of desktop apps written in Ruby as truly native DMG/PKG/APP files on the Mac, MSI/EXE files on Windows, and DEB/RPM files on Linux. Glimmer was the first Ruby gem to bring SWT (Standard Widget Toolkit) to Ruby, thanks to creator Andy Maleh, EclipseCon/EclipseWorld/RubyConf speaker. If you liked Shoes, You'll love Glimmer!

Visualruby is a complete IDE for making graphical user interfaces with ruby. It utilizes glade interface designer to create windows, and uses a library of GUI helpers to make coding GTK+ programs easy. The IDE really helps you organize your files and your thoughts because it names your ruby files and glade files by a naming convention. You files take on the names MyClass.rb, and MyClass.glade. Then you can easily edit the GUI (glade file) by right clicking on your class's file. It also creates .gemspec files for you, then you can right-click on the .gemspec file to install it, or upload it to rubygems.org. You can also yank your gems with one click. To install goto visualruby.net!

GRATR is a framework for graph data structures and algorithms. This library is a fork of RGL. This version utilizes Ruby blocks and duck typing to greatly simplfy the code. It also supports export to DOT format for display as graphics. GRATR currently contains a core set of algorithm patterns: * Breadth First Search * Depth First Search * A* Search * Floyd-Warshall * Best First Search * Djikstra's Algorithm * Lexicographic Search The algorithm patterns by themselves do not compute any meaningful quantities over graphs, they are merely building blocks for constructing graph algorithms. The graph algorithms in GRATR currently include: * Topological Sort * Strongly Connected Components * Transitive Closure * Rural Chinese Postman * Biconnected

PDFBeads is a small utility written in Ruby which takes scanned page images and converts them into a single PDF file. Unlike other PDF creation tools, PDFBeads attempts to implement the approach typically used for DjVu books. Its key feature is separating scanned text (typically black, but indexed images with a small number of colors are also accepted) from halftone pictures. Each type of graphical data is encoded into its own layer with a specific compression method and resolution.

SequenceLogo is a tool for drawing sequence logos of motifs. It gets Positional Count Matrices(PCMs) or IUPAC sequences as input and generates png-logos for a motif. Also one can create logo for reverse complement or even generate logos for a whole collection of motifs. Sequence logos are a graphical representation of an amino acid or nucleic acid multiple sequence alignment developed by Tom Schneider and Mike Stephens. Each logo consists of stacks of symbols, one stack for each position in the sequence. The overall height of the stack indicates the sequence conservation at that position, while the height of symbols within the stack indicates the relative frequency of each amino or nucleic acid at that position. In general, a sequence logo provides a richer and more precise description of, for example, a binding site, than would a consensus sequence (see http://weblogo.berkeley.edu/)

A tool aiming to intuitively enable designers with basic programming experience such as front-end designer/developers to create 2D vector graphics such as designs, icons and art using expressive code rather than common GUI applications for a faster workflow.

VimMate is a graphical add-on to Vim with IDE-like features: it does more than the plain Vim while still being lightweight. Even with the additional features, it stays out of the way for it's main task: editing files with Vim. VimMate adds functionality to Vim by embedding Vim GTK GUI (gVim) within VimMate.

deplate is a ruby based tool for converting documents written in an unobtrusive, wiki-like markup to LaTeX, HTML, "HTML slides", or docbook. It supports page templates, embedded LaTeX code, footnotes, citations, bibliographies, automatic generation of an index, table of contents etc. It can be used to create web pages and (via LaTeX or Docbook) high-quality printouts from the same source. deplate probably isn't suited for highly technical documents or documents that require a sophisticated graphical layout. For other purposes it should work fine. deplate aims to be modular and easily extensible. It is the accompanying converter for the Vim viki plugin. In the family of wiki engines, the choice of markup originated from the emacs-wiki.
