OpenSlide on Windows

Getting OpenSlide for Windows

Precompiled binaries

Regular releases are available from the OpenSlide website.

Building from source

OpenSlide is built for Windows using MinGW-w64. The easiest way to build OpenSlide and its dependencies is by using openslide-bin, which can run on Linux or Windows in a Docker container.

Python

OpenSlide Python is not included in the OpenSlide binary distributions, but prebuilt wheels are available on PyPI. Install with pip install openslide-python and make sure OpenSlide is added to the DLL search path with os.add_dll_directory().

Using OpenSlide on Windows

Optional components

If you distribute a program that uses OpenSlide, you may wish to omit these utility programs:

• openslide-quickhash1sum.exe
• openslide-show-properties.exe
• openslide-write-png.exe
• slidetool.exe

These binaries are only necessary if you use OpenSlide Java:

• openslide.jar
• openslide-jni.dll

Files with names ending in .debug contain debug symbols for GDB, and can also be omitted.

Licensing

If you distribute OpenSlide binaries, you are also required to distribute the corresponding source code for OpenSlide and some of its dependencies. The exact license terms for each component are included in the licenses directory of OpenSlide binary distributions. Complete corresponding sources for official builds and nightlies are distributed in the -winbuild Zip file alongside the binary Zips.
