[gdal-dev] Removing Nodata pixels from raster

[katrin eggert]

Greetings
I have a Geotif with only one Layer with a size of 6000x5000 but from which
I only have a square of 60x100 with bvalid pixels. the remaining are
NOdata. The problem is that this Geotiff is a big file 90MB and without
these NoData values I would have a much smaller raster.
How can I generate a new Geotiff without these noValid values and with
extent adjusted to the valid pixels?
Thank you
Regards,
Katrin E.
