Tracing Paper JS – tool for generating JavaScript coordinates from image

Tracing paper is common tool for illustrators and graphic designers.

I wrote a tool which is able to convert clicks on image into coordinates and use it in JavaScript.

Launch Tracing Paper JS in full screen mode

Just click at the image and tool will record set of coordinates as JavaScript code.

It’s simple app written in JavaScript with AngularJS.

Source code is available at Github: https://github.com/georgik/tracing-paper-js

Composing and playing music with HTML5

I was searching for a web based music note editor. I found HTML5 Cloud Composer from Greg Jopa.

Then I found something more like good old FastTracker: Sonant Live composer.

You can use Sonant Live composer to create tracks with music.

What is even more interesting about this composer is that you can store your song into pure JavaScript file and replay it with js-sonant.

The princeple of js-sonant is quite simple. You just store music structure into song variable and then you call createAudio. It will produce HTML5 audio object with wav rendered from your song tracks.

Here is sample code:

var songGen = new sonant();

for (var t = 0; t < 8; t++)
{
    songGen.generate(t);
}

audio = songGen.createAudio();
audio.loop = true;
audio.play();

Here you can play my simple attempt to make music. :-)

Note: Your browser must support HTML5 audio in order to play this music. Browsers which have support for HTML5 audio: Google Chrome, Firefox, Opera, Safari.

Note 2: Please wait few seconds after you clicked the Play button. You browser will render JavaScript music notation into playable Wav.
