L_DicomGetInfoDS

#include "Ltdic.h"

L_LTDIC_API L_VOID L_DicomGetInfoDS(hDS, pnClass, pnFlags)

Gets information about the file.

Parameters

HDICOMDS hDS

A DICOM handle.

L_UINT32 * pnClass

Pointer to an IOD Class constant which determines the class of information stored in the file. For a list of default IOD Module Constants, refer to IOD Module Constants.

L_UINT16 * pnFlags

Meta-header flags and Transfer Syntax flags that indicate file characteristics. Possible values for the Meta-header flags are:

Value Meaning
DS_METAHEADER_PRESENT [0x0001] The header is present.
DS_METAHEADER_ABSENT [0x0002] The header is absent.

Possible values and combinations for the Transfer Syntax flags are:

Value Meaning
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_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

Any of the available Meta-header flags given above may be combined with any of the available values or combinations of values for the Transfer Syntax flags given above. For example, you may combine DS_METAHEADER_ABSENT with DS_EXPLICIT_VR, or you may combine DS_METAHEADER_PRESENT with DS_BIG_ENDIAN | DS_EXPLICIT_VR, etc.

Returns

None.
