Hello Quincey,
Thanks, I thought that a simple thing like that could be done easier. My background is from web dev (specially Ruby).
That app is just a simple pet project and for that I will use a simple gradient instead of the image. I tried the image because I want a small noise instead of a plain gradient.
But really thanks for all the help, I will study the link that you sent and also study Coregraphics.
