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 to '.8bf' files
with Plugin Commander(PiCo) to use them.
You can download PiCo from http://pico.i-us.com/
About Sample Images
To find that images are seamless, four images
are arranged .
Source images are as follows. 
is transparent area.
This is Convolver which keeps an image seamless.
| Center Coef+128 |
coefficient of current pixel + 128 |
| Top Coef+128 |
coefficient of upper pixel + 128 |
| Left Coef+128 |
coefficient of left pixel + 128 |
| Right Coef+128 |
coefficient of right pixel + 128 |
| Bottom Coef+128 |
coefficient of lower pixel + 128 |
| Bias |
bias |
New Pixel =
(Current Pixel * Center Coef + Upper Pixel
* Top Coef
+ Left Pixel * Left Coef + Right Pixel *
Right Coef
+ Lower Pixel * Bottom Coef) / Sum of Coef
+ Bias
