## Detailed Description

a class handling the DICOM file format (with meta header)

## Constructor & Destructor Documentation

## ◆ DcmFileFormat() [1/2]

DcmFileFormat::DcmFileFormat | ( | DcmDataset * | dataset,
|  | OFBool | deepCopy = OFTrue )

constructor taking an existing dataset for initialization.

Depending on the parameters, a deep or shallow copy is performed.

Parameters

  dataset | the dataset to be inserted into the new DcmFileFormat object. If NULL, an empty dataset is created and inserted instead.
  deepCopy | If OFTrue (default), a deep copy of the dataset is performed. Otherwise only the pointer is copied and the ownership of the dataset is taken over by the DcmFileFormat object.

## ◆ DcmFileFormat() [2/2]

DcmFileFormat::DcmFileFormat | ( | const DcmFileFormat & | old | ) |

copy constructor

Parameters

  old | element to be copied

References DcmFileFormat().

## Member Function Documentation

## ◆ calcElementLength()

virtual Uint32 DcmFileFormat::calcElementLength | ( | const E_TransferSyntax | xfer,
|  | const E_EncodingType | enctype )
| virtual

calculate the length of this DICOM element when encoded with the given transfer syntax and the given encoding type for sequences.

For elements, the length includes the length of the tag, length field, VR field and the value itself, for items and sequences it returns the length of the complete item or sequence including delimitation tags if applicable.

Warning
  Since calcElementLength() returns a 32 bit integer, an overflow during calculation is possible for some derived classes that actually represent a compound value (e.g. items like DcmPixelItem). Such overflows will be detected, in which case the maximum possible value will be returned instead, coinciding with DCM_UndefinedLength.
  The implementation in DcmPixelData may return zero if no conforming representation exists and set the EC_RepresentationNotFound error flag to indicated it.
  When calculation the length of a sequence or an item containing multiple attributes, the implementation may return DCM_UndefinedLength to indicate a value that can not be encoded as a 32 bit length field. It will even do so if "dcmWriteOversizedSeqsAndItemsUndefined" is disabled, but then also set the EC_SeqOrItemContentOverflow error flag (inside getLength()) to indicated it.

Note
  Just check for zero or DCM_UndefinedLength return value and then have a look at the error flag in either case.

Parameters

  xfer | transfer syntax for length calculation
  enctype | sequence encoding type for length calculation

Returns
  length of DICOM element

## ◆ convertCharacterSet() [1/3]

virtual OFCondition DcmFileFormat::convertCharacterSet | ( | const OFString & | fromCharset,
|  | const OFString & | toCharset,
|  | const size_t | flags = 0 )
| virtual

convert all element values that are contained in the dataset and that are affected by SpecificCharacterSet from the given source character set to the given destination character set.

The defined terms for a particular character set can be found in the DICOM standard, e.g. "ISO_IR 100" for ISO 8859-1 (Latin 1) or "ISO_IR 192" for Unicode in UTF-8. An empty string denotes the default character repertoire, which is ASCII (7-bit). If multiple values are given for 'fromCharset' (separated by a backslash) code extension techniques are used and escape sequences may be encountered in the source string to switch between the specified character sets.

Parameters

  fromCharset | name of the source character set(s) used for the conversion
  toCharset | name of the destination character set used for the conversion. Only a single value is permitted (i.e. no code extensions).
  flags | optional flag used to customize the conversion (see DCMTypes::CF_xxx)

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ convertCharacterSet() [2/3]

virtual OFCondition DcmFileFormat::convertCharacterSet | ( | const OFString & | toCharset,
|  | const size_t | flags = 0 )
| virtual

convert all element values that are contained in the dataset and that are affected by SpecificCharacterSet to the given destination character set.

The source character set is determined automatically from the value of the SpecificCharacterSet (0008,0005) element. The defined terms for the destination character set can be found in the DICOM standard, e.g. "ISO_IR 100" for ISO 8859-1 (Latin 1) or "ISO_IR 192" for Unicode in UTF-8. An empty string denotes the default character repertoire, which is ASCII (7-bit). NB: In case of a DICOMDIR, the SpecificCharacterSet in the main dataset is neither checked nor updated, since the Basic Directory IOD has no SOP Common Module.

Parameters

  toCharset | name of the destination character set used for the conversion. Only a single value is permitted (i.e. no code extensions).
  flags | optional flag used to customize the conversion (see DCMTypes::CF_xxx)

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ convertCharacterSet() [3/3]

virtual OFCondition DcmFileFormat::convertCharacterSet | ( | DcmSpecificCharacterSet & | converter | ) |

Parameters

  converter | character set converter to be used to convert the element values

Returns
  status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmSequenceOfItems.

## ◆ convertToUTF8()

virtual OFCondition DcmFileFormat::convertToUTF8 | ( |  | ) |
| virtual

convert all element values that are contained in the dataset and that are affected by SpecificCharacterSet to UTF-8 (Unicode).

The value of the SpecificCharacterSet (0008,0005) element is updated, set or deleted automatically if needed. The transliteration mode is disabled, i.e. the conversion flags are explicitly set to 0 - see convertCharacterSet(). NB: In case of a DICOMDIR, the SpecificCharacterSet in the main dataset is neither checked nor updated, since the Basic Directory IOD has no SOP Common Module.

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ copyFrom()

virtual OFCondition DcmFileFormat::copyFrom | ( | const DcmObject & | rhs | ) |
| virtual

Virtual object copying.

This method can be used for DcmObject and derived classes to get a deep copy of an object. Internally the assignment operator is called if the given DcmObject parameter is of the same type as "this" object instance. If not, an error is returned. This function permits copying an object by value in a virtual way which therefore is different to just calling the assignment operator of DcmElement which could result in slicing the object.

Parameters

  rhs | - [in] The instance to copy from. Has to be of the same class type as "this" object

Returns
  EC_Normal if copying was successful, error otherwise

Reimplemented from DcmSequenceOfItems.
