VTF to IGS: what carries over and what does not
VTF is made of pixels and IGS is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a IGS container, and that determines whether a CAD or design tool can work with it. One VTF file can hold several pages or frames, while IGS 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.
