[gdal-dev] GDAL 1.8.0 and MrSid "no-data" values

[Oyvind Idland]

Hi,

I just updated to 1.8.0 from 1.7, using the MrSid DSDK 8.0.

In order to handle transparency, i have until now used the metadata values
from "IMAGE__NO_DATA_VALUE",
and simply masked away pixels.

After upgrading, the IMAGE__NO_DATA_VALUE yields nothing, neither is it
listed when using gdalinfo.

The band->GetNoDataValue() doesn't give me any hints either.

Should I handle this in a different way ?
