Technical note

How SCN and STP differ in practice

SCN 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.

I regularly work with Leica SCN files in my pathology lab, and reaConverter has been a lifesaver when I need to convert them to TIFF or JPEG for collaboration. The batch processing feature saves me so much time, and the output quality remains excellent, no loss of detail even at high magnifications. The software is intuitive, and I appreciate that it preserves metadata during conversion. Highly recommended for digital pathology workflows!

reaConverter handles straightforward SCN-to-TIFF/JPEG conversions efficiently, which is helpful for sharing slides with collaborators who don’t have Leica software. The interface is user-friendly, and I’ve had no issues with standard brightfield images.
