Image scaler add-on.
2 posts • Page 1 of 1
I've been having an issue with a Moiré type pattern (http://en.wikipedia.org/wiki/Moire) appearing on resized images create by JImageFilter. In the two images shown below, one was resized using bicubic interpolation in Photoshop while the other one was created using JImageFilter. As you can see there is a distinct Moiré pattern on the police officer's utility belt in the second image and it would be great to have a fix for this as it can be quite distracting..!
Resized in Photosop
Resized with JImageFilter
Thanks for looking into it!
Moiré pattern could be avoided by uncommenting "impl=awt" in scaling.properties. Scaling is around twice slower than default implementation (imageio) but image quality is best. We've implemented a new multi-step imageio bilinear scaling algorithm in 2.1, it provides quality/speed in the middle performance of imageio and awt.
