[gdal-dev] GDALPolygonize using float buffers

[Jorge Arévalo]

Hello,

Is there any reason to limit the GDALPolygonize function to read data
in int32 buffers, instead of using 32b float or even 64b double ones?
As I stated in ticket #4005 (http://trac.osgeo.org/gdal/ticket/4005),
I want to code an alternative version using these kind of buffers. But
I don't know if I'm missing something.

Best regards,
