OpenSlide is a C library for reading whole slide image files (also known as virtual slides). It provides a consistent and simple API for reading files from multiple vendors.
OpenSlide can read brightfield whole slide images in several formats:
- Aperio (
.svs,.tif) - DICOM (
.dcm) - Hamamatsu (
.ndpi,.vms,.vmu) - Leica (
.scn) - MIRAX (
.mrxs) - Philips (
.tiff) - Sakura (
.svslide) - Trestle (
.tif) - Ventana (
.bif,.tif) - Generic tiled TIFF (
.tif)
OpenSlide can also provide access to ICC profiles, textual metadata, and associated images such as a slide label and thumbnail.
The API reference is available on the web, and is also included as
doc/html/openslide_8h.html in the source tarball. Additional
documentation is available on the OpenSlide website.
