There are also other aspects to consider, like how the Krita filters are more biased toward black (producing a sharper-looking image in typical use), which also subtly modifies the saturation and hue of high chroma colors.
I tried to arrange the samples in order from crunchiest to blurriest, but this is really difficult to do the Lanczos filter is less aliasing than Krita Bicubic (iris of the eye is rounder), but produces very noticable haloes (very obvious in the text sample). The Gimp "Cubic" filter is almost completely useless without further processing, but its suppression of color artifacts and aliasing is very high. These two filters ought to trade names, but I don't think that will happen based on previous Gimp mailing-list chatter. This results in high-level customization, which can be further enhanced using more scripts and plugins created by the GIMP Community. GIMP offers multiple extensions and flexibility through integration with Scheme, Perl, Python, and other programming languages. My own preferences are toward the blurrier side of the tradeoff matrix, where using "Nohalo" or "Lohalo" depends on the source image. Krita offers integration with Adobe Photoshop and G’Mic. For this post, I'm presenting three 8x crops to compare, so the reader can come to their own conclusions.
Both also include relatively sophisticated interpolation algorithms for scaling, one of the most important aspects of manipulating digital images. These days, we don't have to work nearly so hard to get high-quality high-depth image processing with both Krita and the development version of Gimp offering at least 16-bit ints per channel. This was a wonderful thing to learn, and a real feeling of accomplishment when the high-bit-depth options I wanted paid off.
#Gimp vs krita how to#
Way, way back when I first started using Linux in 2014, I was so concerned with producing digital images with the highest possible quality I learned how to run autotools to compile the edge version of Imagemagick. I've been using OSS for image processing for a few years now, and every so often I like to review the range of alternatives.
