When PNG Meets Javascript

Posted by Charles | January 17, 2008 .

As you’ve known already PGN is a patent-free image format. It provides lossless data compression. Because of these, PGN unofficially stands for “PNG’s Not GIF”.  A PNG file will have bigger size the quality of the image is much better than JPG and GIS. Designers like it. What will happen when those visual people get armed with another tool called JavaScript? The PNG alpha mask demo shows the potential.

It shows how alpha mask applied interactively via JavaScript. You can go there drag and move either the butterfly or the sun and see what’ll happen. It’s not something elaborated but I just love people exploring all the possibilities that could make the web beautiful and interesting.
