Description

I was wondering if there's any provision for handling tileable images... I know that brushes are tileable by default, but in most processors, image tiling/wrapping is simply not supported.

For example, let's say I have an image (texture) I know it's tileable, and I want to apply a gaussian blur with radius 5. The current behavior is that processed pixels close to a boundary would not take in account the pixels of the opposite boundary. The resulting image, when tiled, would show a noticeable sharp seam between tile limits.

Tipically when texture/tiling has an enumeration like this:

WrapModes:

• None
• WrapX
• WrapY
• MirrorX
• MirrorY
