Created attachment 111719 [details] Interpolation causes bluriness of fine detail Hello I use the "Magnifier" desktop effect primarily for two things: 1. When taking a screenshot with Spectacle, to perfectly align the rectangular selection. 2. When examining or taking a screenshot of pixel artifacts in imaging software. In both cases, what I really need to see is an zoom without interpolation, just the view scaled by 400% or so. The magnifier seems to be hardcoded to use linear or cubic interpolation which destroys detail. Please add an option to the Magnifier to not interpolate/use nearest-neighbor interpolation, so that pixels stay sharp when enlarged.
I set the Scale method to 'Crisp' in kcmshell5 kwincompositing But this also affects all other interpolation that is desired elsewhere.
Christopher, if you're referring to Display and Monitor > Compositor > Scale method, that does not solve the issue. In fact, I don't notice a difference between "crisp" and "smooth". This request is specifically about not interpolating the image (or using nearest-neighbor) so that pixels retain their pixel-sharp edges.
I should have checked the image... I use the Zoom effect, not the Magnifier effect.
Sorry, but that is out of bounds of the magnifier effect.
I'm not familiar with this codebase but I am with a few other programs', and it's usually just a choice of ENUM used in the scaling function. The magnifier code sets the interpolation method, does it not? Then this is a request for nothing more than a choice of the ENUM used, via combobox or checkbox.
