Support for Philips isyntax images

[shaneahmed]

It would be useful to add support for Philips isyntax images. Currently, there is lack of open source libraries which support conversion from isyntax. These libraries also require installation of Philips SDK. It would be really helpful if there is a way to support this with an open licence.

Hi @shaneahmed

There is an issue open on openslide for adding the iSyntax-implementation from slidescape. This implementation does not use the SDK and could be a good solution also for converting do DICOM. As this is actively worked on we will monitor the development and, when/if done, implement any needed changes to wsidicomizer.

The issue with slidescape is that it uses GPL-3 license. Therefore, I don't see an integration in the near future unless the license is updated.
But I agree let's keep an eye on this.

The author is willing to license the isyntax part under a more permissive license: openslide/openslide#433 (comment)

That would be great!

Initial support for converting isyntax files is available in the isyntax branch. This uses the python wrapper pyisyntax and libisyntax. It seems to work OK for isyntax but there are some problems with i2syntax. Only the base level is read from isyntax, but a pyramid can be recreated using the add_missing_levels-parameter.
