The operations performed by this tool depend on the Convolve Type:
1. The Blur tool softens the transition of colours that are among elements of the
image and creates the "blurry" effect.
2. In the Sharpen mode, the tool increases the contrast of colours that are among
elements of the image, focuses parts of the image. The tool is applied to areas
with contrasting colours, but does not work on flat areas.
The Rate option adjusts the level of blurring or sharpening. Other options have been
already discussed.
