sam	8c4591f1d9	* blur.c: remove the blurring code and use our generic convolution routine, which correctly recognises the Gaussian kernel as a separable filter. As a result, it is now 50% faster because the normalisation occurs at kernel build time. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2661 92316355-f0b4-4df1-b90c-862c8a59935f	16 年之前
sam	03ca8dc76d	* convolution.c: automatically detect when a convolution filter is separable and switch algorithms to speed up processing. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2660 92316355-f0b4-4df1-b90c-862c8a59935f	16 年之前
sam	89f35cb8fd	* convolution.c: generic convolution method. Does not take advantage of separable kernels yet. git-svn-id: file:///srv/caca.zoy.org/var/lib/svn/libpipi/trunk@2658 92316355-f0b4-4df1-b90c-862c8a59935f	16 年之前
