[gdal-dev] GDALPolygonize hMaskBand with value < than 0

[Royer Alain]

Hi,

I'm not sute if it is a good place to post this. So sorry if it's not. The documentation for the GDALPolygonize function said that a value other than zero will be used as the mask. But after some test, it is a value > than zero that is used as the mask. Is it a bug or a documentation bug ? I would have prefered that any value other than 0 would be used as a mask.
