[ka-Map-users] Panning and zooming question

[Gambin Dejan]

thanks Paul, 

I think box zooming is not difficult to implement so it shouldn't be a
problem to contribute. I am also willing to do translation if
multilanguage interface is something that is in the plan. Also, I have
tried to read my map file (that is using many layers, groups, etc.) and
it doesnpt show so I shall take a look and see where does it "hang"
(without this new feature that is available in cvs, the map was shown
successfully)

regards, dejan

Hi,

panning without reloading the page is done by drawing the map as a 
series of small (200x200 pixel) tiles that are loaded separately.  When 
the user clicks and drags, the images are moved inside the page.  When 
one set of images are off the visible part of the map, they are moved to

the other side and a new set of tiles are loaded.  The 'tiles' are 
rendered using MapServer and so whatever you can get MapServer to draw, 
you can display ... tileindexed raster data should work just fine. 
Overviews just make it more efficient for MapServer to render at 
different scales

The 'box zooming' is not something I am planning to add, but I will take

contributions.
