# SlicerElastix — image registration GUI for 3D Slicer wrapping the elastix
# registration toolbox. PURE-SCRIPTED (Python) module, so — like 3dslicer-openlifu
# — we replicate slicerMacroBuildScriptedModule directly (drop the module's
# Python + resources into Slicer's qt-scripted-modules) rather than running its
# CMake. This needs no find_package(Slicer) and no foundation -devel, so it is
# independent of the C++ extension-build (foundation -45) work.
#
# elastix itself runs as an external CLI (the `elastix` binary, packaged
# separately in this COPR); the module locates it at runtime.

%description
SlicerElastix wraps the elastix intensity-based image-registration toolbox in
3D Slicer's GUI: rigid/affine/BSpline and multi-resolution registration driven
by a database of 100+ ready-made elastix parameter presets, with forward/inverse
transform application. elastix runs as an external command-line tool (packaged
separately); this extension provides the Slicer-side interface and presets.

* Tue Jun 16 2026 Morgan Hough <morgan.hough@gmail.com> - 1.0-0.1.20260218git507db199
- Initial package. SlicerElastix as a pure-scripted 3D Slicer extension:
  install the Elastix module + ElastixLib + 100+ registration-parameter presets
  into qt-scripted-modules (replicating slicerMacroBuildScriptedModule), no
  compilation / no foundation -devel needed. elastix CLI is a runtime Requires.
