Which Lanczos algorithm is used in version 7.6.3.172 ?

[MarcD]

Hi,
I'm comparing the results of different image resizing softwares for enlarging JPG photos.
Light Image Resizer 7.6.3.172 gives excellent results, but I'm wondering which version of Lanczos it's using?
Is it Lanczos 2 or Lanczos 3?
Thank you

Hi there,

the version used is Lanczos 3.

Thanks Phil.
Since it's Lanczos3 it must be the "separable" one because the calculation speed is very fast compared to the "non-separable" Lanczos3 that we find for example in Affinity photo.
