This pure Ruby library can read and write PNG images without depending on an external image library, like RMagick. It tries to be memory efficient and reasonably fast. It supports reading and writing all PNG variants that are defined in the specification, with one limitation: only 8-bit color depth is supported. It supports all transparency, interlacing and filtering options the PNG specifications allows. It can also read and write textual metadata from PNG files. Low-level read/write access to PNG chunks is also possible. This library supports simple drawing on the image canvas and simple operations like alpha composition and cropping. Finally, it can import from and export to RMagick for interoperability. Also, have a look at OilyPNG at https://github.com/wvanbergen/oily_png. OilyPNG is a drop in mixin module that implements some of the ChunkyPNG algorithms in C, which provides a massive speed boost to encoding and decoding.

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!

== Jiveapps These tools are all about making Jive App development as easy as possible. After you install the tools, it only takes a single command to: 1. Create a new app - a simple Hello World application. 2. Set up version control for your code using Git. 3. Host the app code online at Jive's AppHosting server. 4. Register the app on the Jive Apps Marketplace as an app "in development". 5. Install the app on your default app dashboard in the Jive Apps Sandbox. After you install, use this simple workflow to make changes and see them reflected in the sandbox: 1. Make a change to the code on your local machine. 2. Commit the changes to your local Git repository. 3. Push the changes to the remote Jive Apps repository. This automatically updates the hosted copy on the Jive AppHosting server. 4. Refresh the app dashboard or canvas page on the Jive Apps Sandbox and see your changes. Other features: * LiveDev: preview your changes on the Jive App Sandbox in real time * Collaboration: add other developers to your project * OAuth Key Management: associate consumer key/secret pairs with service names for use in your apps

One feature that I'm working on including in this gem is bootstro.js, a 'Guided Tour' feature for your website or app. If you have any other features you would like to see in the gem, please do contact me to let me know and I'll be sure to include them.
