pydicom.pixel_data_handlers.jpeg_ls_handler

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

Functions

get_pixeldata(ds)	Return the Pixel Data as a numpy.ndarray.
is_available()	Return True if the handler has its dependencies met.
needs_to_convert_to_RGB(ds)	Return True if the Pixel Data should to be converted from YCbCr to RGB.
should_change_PhotometricInterpretation_to_RGB(ds)	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(ds: Dataset) → numpy.ndarray

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() → bool

Return True if the handler has its dependencies met.

pydicom.pixel_data_handlers.jpeg_ls_handler.needs_to_convert_to_RGB(ds: Dataset) → bool

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(ds: Dataset) → bool

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: UID) → bool

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.
