Hi,

I am wanting to create a function that can blend the edges of one image to another by a set percentage.

Does anyone know if such a function already exsists, have had a scout through the archives but have not unearthed anything.

I suppose what I need is a function that alpha's the top image edges by a variable amount, dependant on the shade of the pixel underneath it.

Any ideas?

Cheers Rob,

I'll take a look.

I did a cross-fade routine some time ago, it even takes percentages as a parameter:
