Changelog#

0.1.0 (2025)#

New features#

  • load_and_align: automatic MALDI + H&E registration using cv2.warpAffine with full 360° rotation search

  • add_qupath_annotations: add QuPath GeoJSON annotations to an existing sdata object

  • graphpca_spatialdata: PCA with optional spatial smoothing via graph Laplacian

  • get_kmean_clusters: k-means clustering on GraphPCA scores

  • Add_Pseudo_Image: create spatial images from obs columns

  • launch_landmark_gui: interactive napari landmark alignment tool

  • normalize_spatialdata: TIC and RMS normalisation

  • he_spatialdata: load H&E images as SpatialData objects

Breaking changes from 0.0.1#

  • load_and_align now uses cv2.warpAffine for canvas construction (replacing PIL rotate), ensuring annotation and image coordinates are derived from the same matrix

  • _transform_geojson signature changed: takes M_stored directly instead of individual rotation parameters
