DPARS service
WSI-Forge
A full-resolution normalization layer for scanner interoperability
Purpose
Designed as an independent, observable module.
WSI-Forge creates full-resolution pyramidal OME-TIFF derivatives when a source format requires normalization, while preserving provenance and keeping archival derivatives separate.
Capabilities
Full-resolution pyramidal OME-TIFF
Associated-image preservation when present
Physical pixel-size preservation
Explicit source → derivative lineage
