Can't resize PNG or GIF using Lanczos

[Trollo]

NConvert v.4.17

Code: Select all

nconvert -ratio -rtype lanczos -resize 300 200 -out png -o H:\Downloads\2004.03.18\1.png  "H:\Downloads\2004.03.18\1_big.png" 

What`s wrong?

With Version 3.99 it will work! (with -rtype linear )

best regards

NConvert v.4.17

Code: Select all

nconvert -ratio -rtype lanczos -resize 300 200 -out png -o H:\Downloads\2004.03.18\1.png  "H:\Downloads\2004.03.18\1_big.png" 

What`s wrong?

I've just reproduced your problem: nconvert does create the output file, but the output image has exactly the same size as before. With Bilinear resampling (-rtype linear) this works o.k., so this must be a bug specific to Lanczos resampling.
