L_DicomInitDS

Summary

Creates the data set, inserting the appropriate elements for the specified class.

Syntax

#include "Ltdic.h"

L_LTDIC_API L_VOID L_DicomInitDS(hDS, nClass, nFlags)

Parameters

HDICOMDS hDS

A DICOM handle.

L_UINT32 nClass

Value that specifies the class. For a list of default values, refer to the IOD Class Constants.

L_UINT16 nFlags

Transfer Syntax flag that indicates the organization of the data set and the type of image compression used. Possible values and combinations are:

Value	Meaning
0	[0x0000] Use the default combination of: DS_LITTLE_ENDIAN \| DS_EXPLICIT_VR \| DS_COMPRESSION_NONE
DS_LITTLE_ENDIAN	[0x0004] Byte order is Little Endian.
DS_BIG_ENDIAN	[0x0008] Byte order is Big Endian.
DS_IMPLICIT_VR	[0x0010] The Value Representation is implicit.
DS_EXPLICIT_VR	[0x0020] The Value Representation is explicit.
DS_ADD_MANDATORY_ELEMENTS_ONLY	[0x1000] Insert only the mandatory elements. All other elements will not be inserted. This flag can be added to any other valid combination of flags.
DS_ADD_MANDATORY_MODULES_ONLY	[0x2000] Insert only the mandatory modules. All other modules will not be inserted. This flag can be added to any other valid combination of flags.
DS_LITTLE_ENDIAN \| DS_IMPLICIT_VR	Little Endian Byte Order/Implicit Value Representation
DS_LITTLE_ENDIAN \| DS_EXPLICIT_VR	Little Endian Byte Order/Explicit Value Representation
DS_BIG_ENDIAN \| DS_EXPLICIT_VR	Big Endian Byte Order/Explicit Value Representation

Returns

None.

Comments

Example

This example initializes the Data Set

L_INT DicomInitDSExample(L_VOID) 
{ 
   HDICOMDS hDS; 
 
   hDS = L_DicomCreateDS(NULL); 
   L_DicomInitDS(hDS, CLASS_XA_BIPLANE_IMAGE_STORAGE_RETIRED, DS_METAHEADER_PRESENT |  
                                              DS_LITTLE_ENDIAN |  
                                              DS_EXPLICIT_VR |  
                                              DS_GROUP_LENGTHS |  
                                              DS_LENGTH_EXPLICIT); 
   L_DicomFreeDS(hDS); 
 
   return DICOM_SUCCESS; 
}
