Hi Jukka Rahkonen,
I got the problem solved. Thanks to Mr. Bovermyer.
<http://osgeo-org.1560.x6.nabble.com/Trying-to-get-nodata-in-GeoTIFF-to-display-as-transparent-td3853784.html>
In my case, the pixel value 255 for each band was causing me a headache.
So, I solved the issue using gdalwarp function:
gdalwarp -srcnodata 255 -dstalpha input.tif output.tif
Now, make sure the type is -dstalpha
I hope it helps
Regards
Julierme
