# Tileable Blur

## Overview

Example for the Tileable filter

Original

Filter Tileable Blur applied

Tileable Blur is actually implemented by a Script-Fu script that invokes the Gaussian blur plug-in.

This filter is used to soften tile seams in images used in tiled backgrounds. It does this by blending and blurring the boundary between images that will be next to each other after tiling.

If you want to treat only images borders, you can't apply filter to the whole image. The solution to get the wanted effect is as follows:

- Duplicate layer ( Layer Duplicate Layers ) and select it to work on it.

- Apply Tileable Blur filter with a 20 pixels radius to this layer.

- Select all (Ctrl A) and reduce selection ( Selection Shrink ) to create a border with the wanted width.

- Give a feathered border to the selection by using Selection Feather .

- Delete selection with Ctrl K.

- Merge layers with Layer Merge down .

## Activating the Filter
