I'd like to create a scaleable multi-resolution web effect similar to iBooks and started by building on this tutorial.
The problem is with the background image:
As you can see it has two masks on it that give it that special effect:
What I want to do is create a background that will fit any resolution, for this I need a tileable version of the image background and a translucent PNG mask image which I can scale on top of that tileable image to give a similar effect.
I have no idea how to convert the mask layers above into a simple raster that I can save as a standalone PNG file. I tried replicating the look using a translucent radial gradient but didn't get anywhere.
Without the mask the image looks like this which is allot less compelling:
Any tips on how to easily make a texture tileable will also be appreciated but I can probably manage this myself. Thanks.
