LDicomDS::GetInfoDS

#include "Ltdic.h"

L_VOID LDicomDS::GetInfoDS(pnClass, pnFlags)

L_UINT32 *pnClass;

/* pointer to an IOD Class constant */

L_UINT16 *pnFlags;

/* flags that indicate file characteristics */

Gets information about the file.

Parameter

Description

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.

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:

 

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

 

DS_LITTLE_ENDIAN | DS_EXPLICIT_VR

 

DS_BIG_ENDIAN | DS_EXPLICIT_VR

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.
