anonymous / pngencode.cpp
Created April 6, 2011 23:19
I just read the png spec, and came up with this as a minimal, zlib based png encoding of a truecolour image with 1-4 channels
// by alex evans, 2011. released into the public domain.
// based on a first ever reading of the png spec, it occurs to me that a minimal png encoder should be quite simple.
// this is a first stab - may be buggy! the only external dependency is zlib and some basic typedefs (u32, u8)
//
// more context at http://altdevblogaday.org/2011/04/06/a-smaller-jpg-encoder/.

bug fix png encoder
// by alex evans, 2011. released into the public domain.
// based on a first ever reading of the png spec, it occurs to me that a minimal png encoder should be quite simple.
// this is a first stab - may be buggy! the only external dependency is zlib and some basic typedefs (u32, u8)
//
// VERSION 0.02! now using zlib's crc rather than my own, and avoiding a memcpy and memory scribbler in the old one
// by passing the zero byte at the start of the scanline to zlib first, then the original scanline in place. WIN!

Web Audio Context API

Web Audio Context API

The Web Audio Context API surprised me in how fully featured it is. Most of the docs and tutorials I found on it are from late 2011 so it shows that I'm late getting to the party. Despite the time passing it appears to only have great support in Chrome (This life best viewed in Chrome :p ).

The following constructor creates a shiny new AudioContext Object:

var audioContext = new webkitAudioContext();

A very simple, seedable JavaScript PRNG. NOTE: Please read comments on why this is not a good choice.

Simple window.fetch wrapper.
(function() {
function status(response) {
if (response.ok) {
return response
} else {
var error = new Error(response.statusText || response.status)
error.response = response
throw error
}
}
