[gdal-dev] GDAL 1.6.0 GDALValidateCreationOptions

[Even Rouault]

Hi,

Create()/CreateCopy() shouldn't fail if there's a warning due to 
GDALValidateCreationOptions(). At least, I don't understand how this can 
happen. Do you notice that behaviour with a specific driver ? I couldn't 
reproduce a failure.

For example, something like:
gdal_translate foo.tif bar.tif -co BAD_OPTION=YES

just emits "Warning 6: Driver GTiff does not support BAD_OPTION creation 
option" but the translation is done correctly.

As far as avoiding the warning itself, there's always the possibility of 
querying the GDAL_DMD_CREATIONOPTIONLIST metadata item on the driver and look 
for the "TFW" string in it to see if the option is supported or not.

What would be your idea to make it optional ? At compilation time ? Run time ? 

Regards,
Even
