Hi all, I am trying to get my head around Gimp and graphic software as a whole and clearly I am a bit thick on the subject so I appologise in advance for my question. I have an image that is 226 x 223 pixels, a website says that is an option in Gimp that will up the quality when I scale it. Low and behold the option isnt available in the Gimp I'm using. I have attached a picture. Is it somewhere else in Gimp?
The 'Sinc (Lanczos3)' is no longer in 2.10. Maybe someone here knows how to bring it back. Personally, I use 'No Halo' for everything now. I think it is (maybe) better. I never could tell much difference between 'Sinc (Lanczos3)' and Cubic.
As far as I know, any scaling algorithm will not improve the quality. At best it will preserve some quality.
