[gdal-dev] Polygonize + 8conn => self intersection?

[Casper Børgesen (CABO)]

Hi all.

I've got a simple question. When using GDAL Polygonize with 8-connectivity on two diagonal pixels (the X's) like this:

X +
+ X

Does this lead to a single polygon with self intersection or a multipolygon with two single polygons?

It seems to give me a single polygon regardless of the geometry type of the output layer.

Regards, Casper
