$map->extent->set method behavior

[Doyon, Jean-Francois]

Dan,

Yup, I got his e-mail. He sent me the necessary corrections ot the code. I
recompiled, and voila !

Now I'm having problems with the zoomrectangle function, I'm getting a sig11
on that too !

So far I've tried :

$pixbox = ms_newPointObj($minpt[0],$minpt[1],$axpt[0],$maxpt[1]);
$extent =
ms_newPointObj($HTTP_POST_VARS["minx"],$HTTP_POST_VARS["miny"],$HTTP_POST_VA
RS["maxx"],$HTTP_POST_VARS["maxy"]);
$map->zoomrectangle($pixbox,$map->width,$map->height,$extent);

And also putting all the variables straight into the zoomrectangle :

$map->zoomrectangle($minpt[0],$minpt[1], ....

I'm gonna try using the zoompoint to pan see if the same thing happens ...

Also, the pixel coordinates, should they be passed with 0,0 top left (As the
ROSA applet does it :) or bottom left ?

Thanks,
J.F.
