[ka-Map-users] Re: ecw imageformat problems

[Luca De Felice]

I thought maybe the problem is related to the server linux debian, because I have installed FGS package, but I don't know if there is, for default, the ability for ECW.
Does somebody know if it is necessary to recompile the GDAL library with ECW support with FGS?
thank you very much

  Subject: ecw imageformat problems


  Hi kamappers!
  I need some help from someone because I've implemented a webgis with kamap, but when I tried to publish ecw raster image I found only blank image in the tiles.
  I know there is some problem with the image format when it is used the ecw format, but I thought to fix using "jpeg" format.
  here is the setting in config.php==>
  $aszGMap2 = array (

  'title' => 'Dati stazioni di misura',

  'path' => '../../map/dati_stazioni.map',

  'scales' => array(2000000, 1000000, 500000, 100000, 50000, 12000, 2000),

  'format' =>'JPEG'

  /* Sample authorized_users entry. See auth.php for more details:

  * ,'authorized_users' => array('popplace' => array('user1', 'user2'),

  * 'park' => array('user1')

  */

  );

  and here is the settting in the mapfile==>
