ConvolutionFilter Class
The ConvolutionFilter class applies a matrix convolution filter effect. A convolution combines pixels in the input image with neighboring pixels to produce a new image. A wide variety of image effects can be achieved through convolutions, including blurring, edge detection, sharpening, embossing, and beveling. The matrix should be specified as a 9 point Array. See http://docs.gimp.org/en/plug-in-convmatrix.html for more info.
