[Gdal-dev] PCT and ECW

[Andrew Williams]

Dear all,
I have a problem with a group of images that have PCT's
 
I've mosaicked them and needed to set the -pct option otherwise they came out very dark and murky.
 
What I want to do is gdal_translate them to ECW
 
When I do this I get the following error
 
ERROR 6: SetColorTable() Not supported by this dataset.
ERROR 5: Destination Band 1 appears to be read-only.
 
Any clues?
