Is there any plan to support lanczos algorithm for resampling images in the future?
Thanks,
Massimo

    Massimo,

    This is the first time I've heard of Lanczos resampling, but I've added it to our todo list.

    Thanks,

    Thanks!
    I can add that Gdal tools already support it.
    The result of the resampling when downgrading image resolution seems to be better than bicubic in terms of noise and better than spline in terms of blur.
    The overall visual impression seems to be a better readable image..
    Please if possible let me know as soon as something is ready to be used with GM even if it is not an official release.
    Regards,
    Massimo
