mapextent

[Richard Jansen]

Hi MapServer fans,

Just added myself to The List. Since one week i'm into the MapServer world.
Now it's time to get some help of you.

I want to zoom in every time i click my 'zoom in' button. Wat i do is the
following (MapScript):

$extent = $layer->getExtent();
$map->setExtent($extent->minx+10000, $extent->miny+10000, $extent->maxx-
10000, $extent->maxy-10000);
$map->save("tmpmapfile.map");

I put the tmpmapfile name in a session so i can use it on and on to zoom in
multiple times.

The original extent is: 13537 306848 278002 619116 (my little country the
Netherlands). Wat i want to get is: 23537 316848 268002 609116 as my new
mapextent. But this is wat i get: -364.000000000004 316848 291903 609115

The problem seems to bee de $map->save() because if no new extent is set,
the new extent (the same as the orginal) contains wrong coords.

Has anybody an idee to solv this? Thanks!!

Richard
