## Detailed Description

Reader ala DOM (Document Object Model)

This class is a non-validating reader, it will only performs well- formedness check only, and to some extent catch known error (non well-formed document).

Detailled description here

A DataSet DOES NOT contains group 0x0002 (see FileMetaInformation)

This is really a DataSet reader. This will not make sure the dataset conform to any IOD at all. This is a completely different step. The reasoning was that user could control the IOD there lib would handle and thus we would not be able to read a DataSet if the IOD was not found Instead we separate the reading from the validation.

Note:
  From GDCM1.x. Users will realize that one feature is missing from this DOM implementation. In GDCM 1.x user used to be able to control the size of the Value to be read. By default it was 0xfff. The main author of GDCM2 thought this was too dangerous and harmful and therefore this feature did not make it into GDCM2

Warning:
  GDCM will not produce warning for unorder (non-alphabetical order).

virtual bool gdcm::Reader::Read | ( |  | ) | `[virtual]`

Main function to read a file.

Reimplemented in gdcm::PixmapReader, gdcm::ImageReader, gdcm::SegmentReader, and gdcm::SurfaceReader.

Examples:
  ChangeSequenceUltrasound.cxx, ClinicalTrialAnnotate.cxx, csa2img.cxx, DiffFile.cxx, DumpADAC.cxx, DuplicatePCDE.cxx, ELSCINT1WaveToText.cxx, ExtractEncryptedContent.cxx, FixBrokenJ2K.cxx, gdcmrtionplan.cxx, gdcmrtplan.cxx, GenLongSeqs.cxx, GenSeqs.cxx, GetSequenceUltrasound.cxx, HelloWorld.cxx, iU22tomultisc.cxx, LargeVRDSExplicit.cxx, PatchFile.cxx, pmsct_rgb1.cxx, ReadAndDumpDICOMDIR.cxx, ReadAndPrintAttributes.cxx, ReadExplicitLengthSQIVR.cxx, ReadGEMSSDO.cxx, rle2img.cxx, and TestReader.cxx.

bool gdcm::Reader::ReadDataSet | ( |  | ) | `[protected]`

bool gdcm::Reader::ReadMetaInformation | ( |  | ) | `[protected]`

bool gdcm::Reader::ReadPreamble | ( |  | ) | `[protected]`

bool gdcm::Reader::ReadSelectedTags | ( | std::set< Tag > const & | tags | ) |

Will only read the specified selected tags.

bool gdcm::Reader::ReadUpToTag | ( | const Tag & | tag,
|  | std::set< Tag > const & | skiptags = `std::set< Tag >()`
| ) |  |

Will read only up to Tag

Parameters:

  tag | and skipping any tag specified in
  skiptags |

void gdcm::Reader::SetFile | ( | File & | file | ) | `[inline]`

Set/Get File.

void gdcm::Reader::SetFileName | ( | const char * | filename_native | ) |

Set the filename to open. This will create a std::ifstream internally See SetStream if you are dealing with different std::istream object
