Version: 2.7 (using KDE 4.7.2) OS: Linux Large images (JPGs) scaled down by Gwenview look somewhat blurry on-screen. I first noticed this when my vacation pictures looked much better as Windows desktop wallpaper compared to viewing them in Gwenview. Note that Gwenview is, among other things, an image viewer, so presenting images in the best possible quality is an important feature. While I realize that there is a quality/speed trade-off here I still think that fixing the current scaling algorithm is important. Optionally Gwenview could even offer a sharpening filter to improve image quality for presentations. Reproducible: Always Steps to Reproduce: For comparison I suggest taking a large image (12 MP) and scaling it to desktop size using Gimp. Then compare scaled and unscaled image using Gwenview in fullscreen mode. The image scaled by Gimp will look sharper -- and IMHO better. Actual Results: Blurry image Expected Results: Image at least as sharp as Gimp version

This should be fixed in 4.11.0. Please test and reopen if you don't think it's good enough now.
