26 		 * Used to adjust the filter algorithm used when resizing images.
27 		 * Different filters experience varying degrees of success with
28 		 * various images and can take significantly different amounts of
29 		 * processing time. ImageMagick uses the LanczosFilter by default
30 		 * since this filter has been shown to provide the best results for
31 		 * most images in a reasonable amount of time. Other filter types
32 		 * (e.g. TriangleFilter) may execute much faster but may show
33 		 * artifacts when the image is re-sized or around diagonal lines.
34 		 * The only way to be sure is to test the filter with sample images.
35 		 * 
36 		 * See_Also: $(LINK2 http://www.imagemagick.org/Usage/resize/,
37 		 *     Resize Filters) in the Examples of ImageMagick Usage.
