Hi,
could you run a gdalinfo on your origin file and provide us the output?
Wondering if its datatype is float and a straight gdal_translate (without scaling applied) truncate all values when going to Byte PNG.



Cheers,
Daniele

Hello!
My name is Belén and i'm trying to convert a .bil file (.bil and .hdr) to a .png using gdal_translate, it seems to work fine, there are no error messages but when I open the .png file, I only have a big completely black square.


There's some special thing I should be doing? I'd appreciate any help, because I'm completely lost.

Thank you very much in advance.

Regards.

Belén Muñoz.
