Noel Grandin commented on PIVOT-380:
------------------------------------
This appears to be a limitation of java.awt.image.ConvolveOp, since it does not
apply the Kernel at the edges.
It could probably be worked around by creating a temporary image with a 1-pixel
border, running blur on the input image into the temporary image, and then
clipping the temp image before writing to the output.
