L_LTDIC_API L_VOID L_DicomInitDS(hDS, nClass, nFlags)

HDICOMDS hDS;	/* a DICOM handle */
L_UINT32 nClass;	/* class constant */
L_UINT16 nFlags;	/* flag */

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

Parameter	Description
hDS	A DICOM handle.
nClass	Value that specifies the class. For a list of default values, refer to the IOD Class Constants.
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
	DS_LITTLE_ENDIAN \| DS_EXPLICIT_VR
	DS_BIG_ENDIAN \| DS_EXPLICIT_VR

Returns

None.

                                              DS_LITTLE_ENDIAN | 
                                              DS_EXPLICIT_VR | 
                                              DS_GROUP_LENGTHS |
