[gdal-dev] GDAL Polygonize with Uint32

[Nikolaos Ves]

Hi list,

Currently, GDALPolygonize [0] reads the data to an int32 buffer before
processing them.

If I invoke the function with UInt32 data, will the data be
casted/truncated to Int32 and polygonized improperly or can I use it as it
is?

Nikos
