A quick little Java program that can write a JavaScript program that draws a thing inside a canvas so you can use it as a pfp on an obscure website.

/**
 * A quick little script that converts an image to a slew of JavaScript that
 * draws a pfp in DSi Paint.<br>
 * This code needs the following script to be run before it to function:<br>
 * <pre>function setColor(r,g,b) {
 * context.strokeStyle = 'rgb('+r+','+g+','+b+')';
 * context.fillStyle = 'rgb('+r+','+g+','+b+')';
 * statusdiv.innerHTML = 'Color set to ('+r+','+g+','+b+')';
 * colordiv.style.background = 'rgb('+r+','+g+','+b+')';
 * }</pre><br>
 * Once the code is outputted, type the above function and then copy/paste
 * the given code in the output file and run it. It should paint a new profile 
 * picture in the DSi Paint application, which you can then save as a picture
 * for later use as a pfp.
