Title:
Artifacts when scaling down with Sinc Lanczos3
Status in “gimp” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: gimp
Scaling down a solid white field with the Sinc algorithm causes a
weird thatched-pattern to appear. I've seen this before but now have
an easy way to reproduce. I'm not sure whether the resolutions
matter, but here's how I'm currently reproducing:
1. Create a new RGB image filled with solid white, size 5616x3744 (size of 5D
Mark II images, what I was editing when I found it)
2. Scale down to 1200x800 using "Sinc (Lanczos3)" Interpolation
3. There will now be a weird thatched-pattern in the image, even though it
should be completely #ffffff pixels
I attached the resulting image, saved as a PNG.
