Typescript - How do I store a reference to a constructor. A CoffeeScript class that parses and renders SVG paths to the <canvas> element. Faster Canvas Pixel Manipulation with Typed Arrays. Edit: See the section about Endiannes.
Typed Arrays can significantly increase the pixel manipulation performance of your HTML5 2D canvas Web apps. This is of particular importance to developers looking to use HTML5 for making browser-based games. Dealing with SVG images in mobile browsers - Adventures in WebKit land. When browsing the web with my retina iPad, I often see websites that could have used SVG for their cartoon-like graphics, but used PNG instead.
It seems weird, because most likely those images have been created with some vector graphics editor and then exported or converted to bitmap images. SVG has been supported in most browsers for years, but still it seems that developers are not yet comfortable with using SVG images on their websites. SVG is quite well-supported in mobile browsers.

Evanw/glfx.js. Making Image Filters with Canvas. Introduction The HTML5 canvas element can be used to write image filters.
What you need to do is draw an image onto a canvas, read back the canvas pixels, and run your filter on them. You can then write the result onto a new canvas (or heck, just reuse the old one.) Sounds simple? Good. Processing pixels. Code inComplete - Binary Tree Bin Packing Algorithm. I recently built a ruby gem for auto generating CSS Sprites.
It’s simple and flexible, and can be used to generate sprites in either a horizontal or a vertical layout. This works great for most use cases, but has a couple of downsides: TheoryNine Interactive Development Labs. Formula.js. Codiad/Codiad. How to Create and Use Symlinks on a Mac. In my recent post about pairing SSD and HDD storage inside a MacBook Pro, I used a little-known command line feature to redirect some of my user folders from the SSD to the hard drive.
I wanted OS X to still refer to the default locations of ~/Documents, ~/Downloads and so on for these folders, but I wanted to use the storage space on the big drive for these kinds of files. Symbolic Links (symlinks) are a function of the UNIX underpinnings of OS X to create something like an alias, but at a low-level in the filesystem. Aliases Aliases were introduced in Mac OS System 7 and were then carried forward to Mac OS X. Gre/glsl.js. » Floyd-Steinberg dithering in JavaScript. There are many “smart” algorithms in 2D graphics and Floyd-Steinberg error diffusion is one of them.
Attached demo demonstrates a dithering on webcam output (or Bucks Bunny video, when webcam is not available). Open demo in the new window What is the problem The problem is, that we have an image (table of pixels) in format, which uses lots of colors (hundreds, thousands, millions …) and we want to display it with less colors, and we already have both palettes. The guide to implementing 2D platformers. Having previously been disappointed by the information available on the topic, this is my attempt at categorizing different ways to implement 2D platform games, list their strengths and weaknesses, and discuss some implementation details.
The long-term goal is to make this an exhaustive and comprehensible guide to the implementation of 2D platform games. If you have any sort of feedback, correction, request, or addition – please leave it in the comments! Disclaimer: some of the information presented here comes from reverse engineering the behavior of the game, not from its code or programmers. It’s possible that they are not ACTUALLY implemented in this way, and merely behave in an equivalent way. Also note that tile sizes are for the game logic, graphical tiles might be of a different size.
I can think of four major ways in which a platform game can be implemented. Type #1: Tile-based (pure) Character movement is limited to tiles, so you can never stand halfway between two tiles. PhoneGap Android Plugin to Extract ZipFile. Hello Folks, Its about after 2 months I thought of writing a post.
So here is it. I was thinking to extract a .zip file from PhoneGap on android and I ended up implementing a plugin for it. Include the below .java file with the same package mentioned. /* Author: Vishal Rajpal Filename: ExtractZipFilePlugin.java Date: 21-02-2012*/
Android. Eclipse. KSWEB. Cache “nudger” With web technologies generally, and flash specifically, managing cached assets can sometimes feel like walking a tightrope.
If you’ve got a simple slideshow and have occasional updates to the image you want immediately reflected to the client, you’ll often see traditional “cache-busting” methods like appending a random number of the current UTC time to the end of an image.
