[Mapserver-users] Opacity parameter in raster sld

[Bart van den Eijnden]

Hi Assefa,

thanks for the quick action taken. Another question next to Tom's question:

Will this work if I use this on an existing raster layer without a 
ColorMap in the SLD? I just want to change the opacity, not classify the 
raster.

Best regards,
Bart
