[worldKit-dev] Smoothing (Anti-aliasing) of intermediate zooms when using Zoomify

[Mark]

  Hello everyone,

  this is Mark writing. I am new to WorldKit, and I
have a question regarding the integration with
Zoomify.

  Here is the problem I have: Some of the zoomed in
images are with smooth appearance, and some are
jagged. It depends on the relation of the size of the
original picture and the size of the scaled down
picture - if the width of the scaled down picture is
exactly the width of the original divided by a power
of 2 - the appearance is smooth. If it is a different
size - it is jagged. Example: if the original is
1024px times 1024px the scaled down version 512x512
and 256x256 are smooth (these are produced by
Zoomify), but 378x378 and 768x768 are jagged (because
it is an approximation?).

At the same time - the ZoomifyView smooths out even
the  378x378 and 768x768 versions - there are 3 levels
of pictures but 5 levels of zoom.

On a related note - the <zoomc> tag seems to be
inactive when <zoomifydir> is used.

Any suggestions on getting a smoother appearance using
the very good WorldKit product?

Best regards, Mark
