Extensions
What is an extension ?
An extension could be seen as a delivery package bundling together one or more Slicer modules. After installing an extension, the associated modules will be presented to the user as built-in ones
The Slicer community maintains a website referred to as the Slicer Extensions Catalog to support finding, downloading and installing of extensions. Access to this website is integral to Slicer and facilitated by the Extensions Manager functionality built into the distributed program.
The Catalog classifies extensions into three levels of compliance:
- Category 1: Fully compliant Slicer Extensions: Slicer license, open source, maintained.
- Category 2: Open source, contact exists.
- Category 3: All other extensions (work in progress, beta, closed source etc).
To publish extensions, developers should consider reading the following pages:
What is the extensions catalog ?
The extensions catalog provides Slicer users with a convenient way to access the extensions previously uploaded on the extensions server:
- from within Slicer with the help of the extensions manager
- from the web: http://slicer.kitware.com/midas3/slicerappstore
Why there are no windows 32-bit extensions available ?
- Win 32 has a very limited amount of memory available to an application.
- Many registration and segmentation algorithms fail on that platform because they run out of memory, when used with state of large data.
- Some of these failures are just that, some can crash slicer. Even though the "real" failure is caused by overextending the capabilities of the hardware (in a way the users fault), it appears to the user that Slicer does not work.
- If you search the archives of slicer-users there are several such complaints until we started to discourage people to use 32 bit.
