#include "Ltdic.h"

L_LTDIC_API L_VOID L_DicomInitDS(hDS, nClass, nFlags)

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

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.
