(Sharpening will help
Someone asked me recently about scaling up cartoon images (e.g. to turn a small carton image into desktop wallpaper) and had the impression that something like this might work. But I wasn't able to find any information on these techniques on the web. For a cartoon, you start with sharp edges and fairly even colors, so the problems aren't the same as with digital photos. Although you can't get more information than was present in the small image, are there techniques that let you scale up while preserving edges, so for instance a thin sharp black line becomes a thick sharp black line rather than a thick blurry grey line? Scaling up in steps didn't seem to make much difference. I thought perhaps indexing to a small number of colors might help, but I still got too many greys on the edges of the blacks. By playing with Levels I was able to sharpen up the scaled images somewhat, but I wonder if there are better ways. Any tips? ...Akkana _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
