pydicom.pixel_data_handlers.jpeg_ls_handler¶

Use the jpeg_ls (CharPyLS) Python package to decode Pixel Data.

Functions

`get_pixeldata`(dicom_dataset)	Return the Pixel Data as a `numpy.ndarray`.
`is_available`()	Return `True` if the handler has its dependencies met.
`needs_to_convert_to_RGB`(dicom_dataset)	Return `True` if the Pixel Data should to be converted from YCbCr to RGB.
`should_change_PhotometricInterpretation_to_RGB`(…)	Return `True` if the Photometric Interpretation should be changed to RGB.
`supports_transfer_syntax`(transfer_syntax)	Return `True` if the handler supports the transfer_syntax.

pydicom.pixel_data_handlers.jpeg_ls_handler.get_pixeldata(dicom_dataset)¶

Return the Pixel Data as a numpy.ndarray.

Returns:	A correctly sized (but not shaped) numpy array of the Pixel Data.
Return type:	numpy.ndarray
Raises:	`ImportError` – If the required packages are not available. `NotImplementedError` – If the transfer syntax is not supported. `TypeError` – If the pixel data type is unsupported.

pydicom.pixel_data_handlers.jpeg_ls_handler.is_available()¶: Return True if the handler has its dependencies met.

pydicom.pixel_data_handlers.jpeg_ls_handler.needs_to_convert_to_RGB(dicom_dataset)¶

Return True if the Pixel Data should to be converted from YCbCr to RGB.

This affects JPEG transfer syntaxes.

pydicom.pixel_data_handlers.jpeg_ls_handler.should_change_PhotometricInterpretation_to_RGB(dicom_dataset)¶

Return True if the Photometric Interpretation should be changed to RGB.

This affects JPEG transfer syntaxes.

pydicom.pixel_data_handlers.jpeg_ls_handler.supports_transfer_syntax(transfer_syntax)¶

Return True if the handler supports the transfer_syntax.

Parameters:	transfer_syntax (uid.UID) – The Transfer Syntax UID of the Pixel Data that is to be used with the handler.
