## Detailed Description

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>
class DcmIODImage<>

Class for managing common image IOD attributes.

At the moment support for the palette-related attributes and the smallest/largest image pixel value attributes is still missing. Also, pixel data must be handled separately. However, pixel-data related attributes are provided by the Image Pixel Module, the Floating Point Image Pixel Module or the Double Floating Point Image Pixel Module, based on the provided template parameter. Modules supported on top of DcmIODCommon: General Image Module and Image Pixel Module.

## Constructor & Destructor Documentation

## ◆ DcmIODImage()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>
template<typename ImagePixel>

DcmIODImage<>::DcmIODImage | ( | OFin_place_type_t(ImagePixel) |  | ) |
| inline

Constructor, constructs new DcmIODImage instance with integer, float or double based Image Pixel Module (i.

e. Image Pixel Module, Floating Point Image Pixel Module or the Double Floating Point Image Pixel Module), based on the provided Image Pixel module type.

## Member Function Documentation

## ◆ clearData()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

virtual void DcmIODImage<>::clearData | ( |  | ) |
| inlinevirtual

Clear (removes) all attributes handled by the modules of this IOD.

IOD Rules are not reset.

Reimplemented from DcmIODCommon.

Reimplemented in DcmSegmentation, and DPMParametricMapBase.

References DcmIODCommon::clearData(), m_GeneralImage, and m_ImagePixel.

## ◆ getGeneralImage()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

IODGeneralImageModule & DcmIODImage<>::getGeneralImage | ( |  | ) |
| inline

Get General Image Module.

Returns
  Reference to General Image Module

References m_GeneralImage.

Referenced by EctEnhancedCT::getGeneralImage().

## ◆ getImagePixel()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

IODImagePixelModuleType & DcmIODImage<>::getImagePixel | ( |  | ) |
| inline

Get Image Pixel Module (variant)

Returns
  Reference to Image Pixel Module

References m_ImagePixel.

## ◆ read()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

virtual OFCondition DcmIODImage<>::read | ( | DcmItem & | dataset | ) |
| inlinevirtual

Read common image module attributes (all those handled by this class) from given item.

Reads attributes from base class DcmIODCommon before. The current content is deleted even if the reading process fails. If the log stream is set and valid the reason for any error might be obtained from the error/warning output.

Parameters

  dataset | Reference to DICOM dataset from which the document should be read

Returns
  EC_Normal if successful, an error code otherwise

Reimplemented from DcmIODCommon.

Reimplemented in DcmSegmentation, DPMParametricMapBase, DPMParametricMapIOD, and EctEnhancedCT.

References clearData(), m_GeneralImage, m_GeneralImageModuleEnabled, and DcmIODCommon::read().

## ◆ write()

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

virtual OFCondition DcmIODImage<>::write | ( | DcmItem & | dataset | ) |
| inlinevirtual

Write current common image module's attributes to DICOM dataset.

Also writes attributes of base class DcmIODCommon afterwards.

Parameters

  dataset | Reference to DICOM dataset to which the current data should be written. The dataset is not cleared before writing to it!

Returns
  EC_Normal if successful, an error code otherwise

Reimplemented from DcmIODCommon.

Reimplemented in DPMParametricMapBase, DPMParametricMapIOD, and EctEnhancedCT.

References EC_Normal, OFCondition::good(), m_GeneralImage, m_GeneralImageModuleEnabled, m_ImagePixel, and DcmIODCommon::write().

## Member Data Documentation

## ◆ m_GeneralImageModuleEnabled

template<OFVARIADIC_DECLARE_TEMPLATE_PARAMETER_PACK_WITH_DEFAULTS(T)>

OFBool DcmIODImage<>::m_GeneralImageModuleEnabled
| private

Denotes whether General Image Module is used in this class (OFTrue) or not (OFFalse).

This switch can be configured using a call to setGeneralImageModuleEnabled(). The default is OFTrue.
