Welcome to MuRa's Filters created with Filter Factory.
This is the filter collection for Photoshop for making seamless patterns.
Filters for seamless images are contained in it.
If you apply them to a seamless image, it keeps seamless.

This filter collection is Freeware. You can use them freely and distribute
them without modifying. But it is forbidden to sell them without permission
of the author.

If '.ffl' files are contained in the archive, you have to convert them

You can download PiCo from http://pico.i-us.com/
