Re: [pmapper-users] zoom to layer raster

[Armin B. <arm...@gm...>]

I checked this "zoom to raster layer" and to my surprise it does seem to 
work correctly, using e.g. Geotiff or Jpeg with world file for the 
raster layer data.

a simple test is

// => adapt map file and layer name <=
$mapFile = "/path/to/test-mapfile.map";
$rLayerName = "test";

$map = ms_newMapObj($mapFile);
$rLayer = $map->getLayerByName($rLayerName);
$rLayerExt = $rLayer->getExtent();
print_r($rLayerExt);


This prints out correctly the raster layer extent in both MS 5.6.6 and 
6.x. You should check your MS version, I guess older ones returned -1 or 
so for raster layers.

Postgis layers do not seem to produce useful results, but for this I 
already added a different approach.
