Hello,
There is some error with monochrome PNG files. The PNG.js can read only a part of an image and then return. Here is an example image:

http://people.sc.fsu.edu/~jburkardt/data/png/fool.png

My base64 encoder produces exactly the same output as this encoder:

http://www.greywyvern.com/code/php/binary2base64

PNG.js can read only 42 lines and then return because it encountered a filter having value as -1. Could anybody help? I tried to debug without success.

awesome example, thanks for sharing. this is good for a situation where you can’t link to an image, and need to embed it in the page.

I told him Base64 was the way to go. This is awesome. If only I could find a use for it.

That is a great technique. Thanks.

I am currently looking for something to parse an image from an image tag:

on a web page.

For example such as:

var imgPNG = document.getElementById(’sourceImg’);

var data = IDontKnowHowToCreateThisFunction(imgPNG); // this is where I am stuck !!!

var png = new PNG(data);

var sOut = “”;
while(line = png.readLine())
{
for (var x = 0; x < line.length; x++){
sOut += line[x];
}
}

Please help me to implement the IDontKnowHowToCreateThisFunction

There was made an attempt to create pure binary PNG data and package it as data URI schema. The restrictions in size of the data URI schema link length in web browsers did not allow to create any real world application.

The pilot code is published as “Non-compressed PNG canvas” project at http://notmasteryet-projects.assembla.com/ (SVN repository can be found at http://code.assembla.com/dKhvyQiuur3PPAeJe5aVNr/subversion/nodes/JS).
