[Mapserver-users] Problem visualizing an image ECW.

[braulioen at ono.com]

Hi at all,

   I'm using PHP/Mapscript in Windows XP, downloaded 
from "http://www2.dmsolutions.ca/webtools/dl", file "mapserver-3.6.6-
dev-win32-php4.3.1-libwww-postgis.zip". This version is compiled with 
support for ECW (from library GDAL). We have a Image Web Server (IWS) 
of ERMAPPER. Now I have added in my map a raster layer with an image 
ECW:

LAYER
  NAME ortofoto
  DATA "ecwp://myserverIWS/myimage.ecw"
  STATUS DEFAULT
  TYPE RASTER
END

But I have a problem. The image is seen correctly, but when I make
zoom in, from a determined scale, the image ECW becomes black. Which
is the problem?

Thanks for any aid.
Braulio Moreno.
