umm... i think i *may* have answered my own question... does it have to
do with the dimensions of the ouput image that is set? i have a final
image that has a 4:3 ratio, and does the setExtent function
automatically account for the image dimensions? It seems so, for when I
do this:
=== PHP code ===
$map->setExtent(-1,-1,1,1);
echo "<pre>final extent is: "; print_r( $map->extent ); echo
"</pre><br>\n";
=== End PHP code ===
I get:
=== HTML Output ===
final extent is: ms_rect_obj Object
(
[_handle_] => Resource id #7
[minx] => -1.33333333333
[miny] => -1
[maxx] => 1.33333333333
[maxy] => 1
)
=== End HTML Output ===
Just threw me...
thanks,
matt

Subject: [UMN_MAPSERVER-USERS] PHP Mapscript: Map extent not being set
to what I am passing setExtent on my map object
Hi,
I am passing an extent to my map object to set it, but it is not being
set to what I am telling it. I cannot find an error -- can someone look
at it? Here's the relevant code:
=== PHP code ===
echo "<pre>buf_max_extent is: "; print_r( $buf_max_extent ); echo
"</pre><br>\n";
$map->setExtent($buf_max_extent[1],$buf_max_extent[2],$buf_max_extent[3]
,$buf_max_extent[4]);
echo "<pre>final extent is: "; print_r( $map->extent ); echo
"</pre><br>\n";
=== End PHP code ===
=== HTTP Output ===
buf_max_extent is: Array
(
[1] => 490059.61375
[2] => 5163285.525
[3] => 764351.51125
[4] => 5388702.975
)
final extent is: ms_rect_obj Object
(
[_handle_] => Resource id #7
[minx] => 476927.2625
[miny] => 5163285.525
[maxx] => 777483.8625
[maxy] => 5388702.975
)
=== End HTTP Output ===
tia,
matt
