[gdal-dev] NoData vs metadata confusion

[Oyvind Idland]

Hello,

stumbled across a problem when reading MrSid:

The MrSid dataset contains 3 bands, R/G/B. None of the 3 bands gives me a
GetNoDataValue(),
however, the metadata contains IMAGE__NO_DATA_VALUE=255,255,255.

Does this mean, that I have to check for both cases ?

The version is GDAL 1.7.2.


Regards,


Oyvind Idland
