createReaderWithNoPixelData

public static DicomReader createReaderWithNoPixelData()

returns a DicomReader with preconfigured TagListener that skips top-level pixeldata. Data Elements after the pixel data will also be read and added to the DicomObject.

Returns:

DicomReader

createReaderWithOffsetTableAndNoPixelData

public static DicomReader createReaderWithOffsetTableAndNoPixelData(ReaderObserver readerObserver)

returns a DicomReader with preconfigured TagListener that skips top-level pixeldata except the basic offset table in case of encapsulated images. The offset table will be located in the first item of the pixel data Data Elements after the pixel data will also be read and added to the DicomObject.

Parameters:

readerObserver - optional ReaderOserver

Returns:

DicomReader
