Here is the explanation from GIMP documentation:\r\n\r\n> The Antialias filter works as follows:\r\n> \r\n> For every pixel,\r\n> \r\n> the filter expands the original pixel in 9 (3x3) new pixels according to the Scale3X algorithm, using the colors of the pixel and its 8 adjacent pixels (extrapolation);\r\n> \r\n> then the filter subsamples the new pixels to a weighted average pixel.\r\n"}}
