Detailed Description

Class representing the "Derivation Image Functional Group Macro".

Member Function Documentation

◆ addDerivationImageItem()

virtual OFCondition FGDerivationImage::addDerivationImageItem	(	const CodeSequenceMacro &	derivationCode,
		const OFString &	derivationDescription,
		DerivationImageItem *&	item
	)

virtual

Convenience function to add an item only having a single derivation code derivation description.

No source images have to provided but can be added later on the resulting DerivationImageItem.

Parameters

derivationCode	Code describing derivation
derivationDescription	Free text description of derivation (can be empty)
item	The created derivation image item if successful, NULL otherwise

Returns: EC_Normal if adding works, error code otherwise

◆ check()

virtual OFCondition FGDerivationImage::check ( ) const

virtual

Checks whether this class contains valid data.

Returns: EC_Normal if data is valid, error otherwise

Implements FGBase.

◆ clone()

virtual FGBase* FGDerivationImage::clone ( ) const

virtual

Returns a deep copy of this object.

Returns: Deep copy of this object

Implements FGBase.

◆ compare()

virtual int FGDerivationImage::compare ( const FGBase & rhs ) const

virtual

Comparison operator that compares the normalized value of this object with a given object of the same type, i.e. the elements within both functional groups (this and rhs parameter) are compared by value! Both objects (this and rhs) need to have the same type (i.e. both FGDerivationImage) to be comparable.

This function is used in order to decide whether a functional group already exists, or is new. This is used in particular to find out whether a given functional group can be shared (i.e. the same information already exists as shared functional group) or is different from the same shared group. In that case the shared functional group must be distributed into per-frame functional groups, instead. The exact implementation for implementing the comparison is not relevant. However, it must be a comparison by value.

Parameters

rhs	the right hand side of the comparison

Returns: 0 if the object values are equal. -1 if either the value of the first component that does not match is lower in the rhs object, or all compared components match but the rhs component is shorter. Also returned if this type and rhs type (DcmFGTypes::E_FGType) do not match. 1 if either the value of the first component that does not match is greater in the rhs object, or all compared components match but the rhs component is longer.

Implements FGBase.

◆ createMinimal()

static FGDerivationImage* FGDerivationImage::createMinimal	(	const OFVector< ImageSOPInstanceReferenceMacro > &	derivationImages,
		const OFString &	derivationDescription,
		const CodeSequenceMacro &	derivationCode,
		const CodeSequenceMacro &	purposeOfReference
	)

static

Convenience function to create a minimalistic FGDerivationImage.

Parameters

derivationImages	The list of SOP instances to reference
derivationDescription	Description of the derivation performed
derivationCode	Coded representation of the derivation description
purposeOfReference	Purpose of referencing the SOP instances

Returns: The created derivation image item, if successful, NULL otherwise

◆ getDerivationImageItems()

virtual OFVector<DerivationImageItem*>& FGDerivationImage::getDerivationImageItems ( )

virtual

Get reference to derivation image items.

Returns: Reference to derivation image items

◆ getSharedType()

virtual DcmFGTypes::E_FGSharedType FGDerivationImage::getSharedType ( ) const

inlinevirtual

Returns shared type of this functional group.

Returns: Always returns DcmFGTypes::EFGS_BOTH

Implements FGBase.

References DcmFGTypes::EFGS_BOTH.

◆ read()

virtual OFCondition FGDerivationImage::read ( DcmItem & item )

virtual

Read Derivation Image Sequence from given item, which can contain zero or more items.

Parameters

item	The item to read from

Returns: Returns EC_Normal if at least one derivation image item could be read or no item exists at all, otherwise an error is returned

Implements FGBase.

◆ write()

virtual OFCondition FGDerivationImage::write ( DcmItem & item )

virtual

Write Derivation Image Sequence (containing contain zero or more items) to given item.

Parameters

item	The item to write to

Returns: EC_Normal if writing was successful, error otherwise

Implements FGBase.
