CurrentVR property (ILEADDicomDS)

VB.NET example	C# example
Visual Basic example	Visual C++ 6.0 example

Syntax	DICOMVRItem CurrentVR
Overview	Refer to Working with Value Representations.

Remarks

Holds the currently selected Value Representation Table item.

CurrentVR has the following Read-Only properties:

Property	Type	Description
Code	short	Code that indicates the type of value stored in the data element. For a list of default values supported by DICOM, refer to Value Representation Constants.
Name	BSTR	Character string that contains the name of the Value Representation. To see the default values for the Value Representation Names, refer to the Default Value Representation Table.
Length	long	The length of the value to be stored in the data element.
Restrict	short	Restrictions on the length. Possible values are given below. For a list of available options, see below.
UnitSize	short	The size of the smallest item that can be stored in the data element.

Internally LEADTOOLS maintains a table or list of available value representations. These value representations can include default value representations available in DICOM, as well as user defined value representations. You can access any of this information, add to the table, or delete items from the table using the XXXVR methods. To see the default values, refer to the Value Representation Table.

Possible values for the Restrict property are given below.

Value	Meaning
DICOM_VR_FIXED	[0x00] Length is a fixed number of bytes.
DICOM_VR_MAXIMUM	[0x01] Length is the maximum number of bytes allowed.
DICOM_VR_MAXIMUM_GROUP	[0x02] Length is the maximum number of bytes allowed per component group
VR_ANY	[0x03] Any length is valid.
VR_NOT_APPLICABLE	[0x04] Length is not applicable

One of the values above may be combined with one of the values below using the bitwise OR ( | ) operator.

DIALOG_VR_BINARY	[0x0100] Binary value.
DIALOG_VR_STRING	[0x0200] String value (The character '\' is used as the delimiter between values for multiple data elements).
DIALOG_VR_TEXT	[0x0400] Text value. (Data elements with this VR cannot be multi-valued).
