Best way to resize an image

[Innocentus]

Which is the best command-line command-combination to resize an existing Image with highest-possible quality? - Is there a Resize-Filter-aquivalent like Photoshop's "Bicubic Sharper"?
Speed doesn't matter.

Thank you very much for your help and support!
With best regards!

Are you shrinking or enlarging your image?

The default filter for shrinking is Lanczos and is probably the best one to use.
The default filter for enlarging is Mitchell according to the page below.

See:

for a list and comparison of all the IM filters.
