Open Source JavaScript Graphic Design Software

The Blockly library adds an editor to your app that represents coding concepts as interlocking blocks. It outputs syntactically correct code in the programming language of your choice. Custom blocks may be created to connect to your own application. Blockly in a browser allows web pages to include a visual code editor for any of Blockly's five supported programming languages, or your own. Blockly plugins are self-contained pieces of code that add functionality to Blockly. Blockly codelabs provide step-by-step instructions on how to use and customize Blockly. From a user's perspective, Blockly is an intuitive, visual way to build code. From a developer's perspective, Blockly is a ready-made UI for creating a visual language that emits syntactically correct user-generated code. Blockly can export blocks to many programming languages.

Fabric.js is a simple yet powerful Javascript HTML5 canvas library that allows you to easily work with HTML5 canvas element in various ways. It is also an SVG-to-canvas (and vice versa) parser. Fabric provides an interactive object model on top of canvas element, so you can create and populate objects on canvas; manipulate the size, position and rotation of these objects; modify properties such as color, transparency and more. You could also group these objects together with just a simple mouse selection. Fabric offers support for touch devices, as well as Node.js support. It currently supports the following browsers: Firefox 2+, Safari 3+, Opera 9.64+, Chrome (all versions), IE10, IE11, and Edge.

The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, AVIF and WebP images of varying dimensions. Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips. Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available. Most modern macOS, Windows and Linux systems running Node.js v10+ do not require any additional install or runtime dependencies. This module supports reading JPEG, PNG, WebP, AVIF, TIFF, GIF and SVG images. Output images can be in JPEG, PNG, WebP, AVIF and TIFF formats as well as uncompressed raw pixel data. Streams, Buffer objects and the filesystem can be used for input and output.

Javascript has evolved into a language capable of handling realtime 3D graphics, via WebGL, and computationally intensive tasks such as physics simulations. These types of applications demand high performance vector and matrix math, which is something that Javascript doesn't provide by default. glMatrix to the rescue! glMatrix is designed to perform vector and matrix operations stupidly fast! By hand-tuning each function for maximum performance and encouraging efficient usage patterns through API conventions, glMatrix will help you get the most out of your browsers Javascript engine.

All-in-one program for creating 2D scrolling games. Compile your games into stand-alone .NET executables or customizable C# source code. The IDE and framework are build on OpenTK, which wraps OpenGL, so generated games can be cross-platform.

Customizable browser based (text/web(WYSIWYG)) file editors environment in PHP (GPL Licensed) with loads of features. (tested only in firefox)

Jalava is a pure Javascript diagram editor. Unlike Windows-based programs, Jalava runs on your web browser. No Flash, no Java applets, no SVG. It is designed to be easily customised, so you can design your own editor using the framework provided.

A petite color palette generator whose entire code fits within a single html file. Link: https://northstrix.github.io/nof-go/ GitHub repository: https://github.com/Northstrix/nof-go

Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy. Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+. Versions will be released as we gather and test new PRs. As there are a lot of browsers being supported it might take a while to accept a PR, we will use the feedback from other users too. You can use the raphaelTest.html to try things, you need to start a server in the root dir to start testing things there.

SvgUP is an open source platform for building interactive Web applications based on SVG components and other web standards like JavaScript, CSS, RDF and DTD. SvgUP allows the separation of concerns by dividing the applications into modules.
