Technical note

VSI to STP: what to expect from the conversion

VSI is made of pixels and STP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STP container.
