Moire samples on resizing.


It's scanned at 600dpi, then resized at 300dpi.
(PS)=Photoshop CS2, (Xn)=Xnview1.96

1) Bilinear also known as moire generator always fails :P
2) Bicubic/Lanczos have sharpaning effects, so they preserve screening, & cause a bit moire. btw, there is no visible difference between bicubic/lanczos at 50% resizing, but if it's resized at random parcentage, lanczos is a bit smooth.
3) Bicubic smoother/Mitchell haven't sharpening effects, then screening is a little reduced. they're very "safe" resizing imo.
4) Bspline gives out similar result to gaussian+resizing. it redusing any noizes while resizing, so you can use it when you'd like to avoid annoying editing. (and I'm using bspline the most :P)
