Sorry if I cover ground that has already been trod. I haven't had time to follow the discussion before now My take: scaling an image to a smaller size forces the program to interpret a group of pixels as a single color/pixel which leads to blockiness and lost quality. If I were trying to reduce the size of an image while preserving definition I would look at changing its resolution ie from 72pix x 72pix to 288pix x 288pix, reducing the images apparant size (to 1/4 the starting size) while keeping all the pixel information. This could be done at the time of printing (setting the printer resolution) or within gimp. If I am in error please let me know HTH -- dh _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
