Recently resurfaced questions as to how one resize a picture.
As I get we will not have Win Api in LB5, so some build-in way is needed.
1) load from disk to given size (like creating light thumbnail from heavy file on a disc)
2) ability to resize picture already in memory, both up and down
3) (optional) alow to select better quality resize if possible.
If your tool supports several filters - allow choosing method
As I get it is better to use different algorithms for up/down, and depending on how much % resize.
Problem is it could heavily depend on a task at hand
(ImageMagic has long article with possible filters,
legacy.imagemagick.org/Usage/filter/
and last page of it has a title "The Best Filter?", have a look)
