0.22.0

Added

• Cache for compressed and decompressed tiles.
• Setting strict_tile_size_check, defaulting to True, to enable parsing of levels with different tile size.

Changed

• Default to placing the image at the middle of the slide if no TotalPixelMatrixOriginSequence is set when producing DICOM metadata .
• Use Unix epoch as default datetime when producing DICOM metadata.
• Group instances to pyramids with a configurable threshold to allow small differences in TotalPixelMatrixOriginSequence.

Fixed

• Parsing of native pixel data with padded lenght.
• Check for supported transfer syntax when DICOMWeb client returns an iterable of frames.
• Fix for order of transfer syntax to check.
• Use ImageType DERIVED instead of ORIGINAL when saving resampled volume instances.
• Thread-safe parsing of pixel data frame index.

0.21.4

Fixed

• Loading of files with missing TotalPixelMatrixOriginSequence.

0.21.3

Fixed

• Missing WholeSlideMicroscopyImageFrameTypeSequence in produced DICOM dataset for some image types.
• Do not insert empty ContainerComponentSequence and PrimaryAnatomicStructureSequence into produced DICOM dataset.
• Only insert SpacingBetweenSlices into produced DICOM dataset if multiple focal planes.
• Prefer use of ZOffsetInSlideCoordinateSystem in main DICOM dataset to attribute in SharedFunctionalGroupsSequence/PlanePositionSlideSequence.

0.21.2

Fixed

• Unpinned requirement for numpy to support numpy 2.

0.21.1

Fixed

• Restricted imagecodecs to exclude version 2024.9.22 due failing bug when encoding jpeg.

0.21.0

Added

• Support for pydicom 3.0. This requires Pyhton >3.10.

Removed

• Support for Python 3.9.
• Support for pydicom <3.

Fixed

• Missing support for using fsspec in some methods.

0.20.6

Fixed

• Fixed version of pydicom to <3.0 to avoid breaking changes.

0.20.5

Fixed

• Removed debug printing.

0.20.4

Fixed

• Error when calculating downscaled image size causing save() with add_missing_levels to fail.
• Missing sort when creating new pyramid levels, causing new levels to be created from a to high resolution level.

0.20.3

Fixed

• Missing handling of pyramid index when creating WsiInstance using create_instance().
