Hi Alan,
Thanks for yours reply! Yes now it's clear pixels are integers... It is
too bad that this simply function mismatches to me. Is there other
recenter function which works with x,y in lonlat? I didn't see something
like that in mapserver/mapscript documentation...
Good day,
Donatas.

Donatas,
The x,y given to the zoomPoint function are in PIXEL, not lonlat. You cannot
specify a half pixel. That said, pixel are integers, not double.

HGood day,
I have some problem. I want to recenter my map exactly to users given
georeferenced coordinates. For that purpose I use php mapscript function
- zoompoint(ZOOMFACTOR,$myXY, WIDTH, HEIGHT, EXTENT) with ZOOMFACTOR=1.
But this function doesn't work correctly. ZoomPoint function centers map
to rounded x,y position (then I have myX 235.5px and myY 330.42 it
rounds to 235px, 330px) and moves map to incorect center coordinates.
What should I do in this situation, please give me some advice, how
recenter map with best precision.
Thanks,
Donatas.
