    React Color

    React Color

    Color pickers from Sketch, Photoshop, Chrome, Github, and Twitter

    13 different pickers, for Sketch, Photoshop, Chrome and many more. Make your own, use the building block components to make your own. Color controls what color is active on the color picker. You can use this to initialize the color picker with a particular color, or to keep it in sync with the state of a parent component. Pass a function to call every time the color is changed. Use this to store the color in the state of a parent component or to make other transformations. Pass a function to call once a color change is complete. To make a custom color picker, create a top-level component that will act as the bridge with the CustomPicker high order component. Wrap the export with the CustomPicker function. Every color picker provided is made up of a collection of helper components. Those components are accessible for you to use to make a custom color picker. Use EditableInput to display an input / label that acts as the single source of truth until the input is blurred.

    The GR module for Julia

    Plotting for Julia based on GR

    This is the GR module for Julia. It places a Julia interface to GR, a universal framework for visualization applications. GR allows users to create high quality, engaging visualizations, everything from 2D graphs to complex 3D scenes. With this module simply type in Julia 'using gr', and you can instantly start calling functions in the GR framework API. GR is based on an implementation of a Graphical Kernel System (GKS) and OpenGL. As a self-contained system, integration into existing applications is quick and easy-- simply use a direct call from Julia with ccall syntax.

    Agar

    Agar

    Cross Platform GUI Toolkit

    Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.
