Filter Tileable Blur applied


This tool 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.

[Tip] Tip

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:

  1. Duplicate layer (LayerDuplicate Layer) and select it to work on it.

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

  3. Select all (Ctrl+A) and reduce selection (SelectionShrink) to create a border with the wanted width.

  4. Give a feathered border to the selection by using SelectionFeather.

  5. Delete selection with Ctrl+K.

  6. Merge layers with LayerMerge down.

2.7.2. Activate the filter

You can find this filter in the image menu under FiltersBlurTileable Blur.
