Technical note

HEIF to STP: what to expect from the conversion

HEIF 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. One HEIF file can hold several pages or frames, while STP holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
