message.setDICOMSignedLongs¶

Signature: message.setDICOMSignedLongs(nodePath, value, instance*, forceNode*)

Returns: void

Sets the value as a \\ delimited string of signed longs of the first node that matches the nodePath.

Note

When the optional instance value is specified, the nodePath should not include an instance identifier.

Parameters¶

Type	Name	Description	Default
String	nodePath	the DICOM node path
String or Number[]	value	the new node value either as a String or a JS Array of JS Numbers
Integer	instance*	(optional) the match instance to set. Use 1 for the first instance.	1
Boolean	forceNode*	(optional) create the node if it doesn't exist	true

Example¶

// Example: Set DICOM tag values using signed long integers (String or Number[])

// assumes `message` is a DICOM message model object


// Example: value as String (backslash-delimited signed longs)
message.setDICOMSignedLongs(
   "0013,000C",  // nodePath - DICOM tag
   "1\\0\\-1\\0" // value (String of signed longs)
);


// Example: value as Number[] (JS array of numbers)
message.setDICOMSignedLongs(
   "0013,000C",   // nodePath
   [1, 0, -1, 0]  // value (Number[])
);


// Example: value as Number[] with larger values (Long range)
message.setDICOMSignedLongs(
   "0013,000C",
   [123456789, -987654321]
);


// Example: specify instance (1-based index)
message.setDICOMSignedLongs(
   "0013,000C",   // nodePath
   [2, 1, -2, 1], // value
   1              // instance (first match)
);


// Example: create node if it does not exist (forceNode = true)
message.setDICOMSignedLongs(
   "0013,000D",   // nodePath (new tag)
   "5\\4\\-5\\4", // value
   1,             // instance
   true           // forceNode - create if missing
);


// Example: do NOT create node if it does not exist
message.setDICOMSignedLongs(
   "0013,000E",
   [0, 0],
   1,
   false          // forceNode - will NOT create tag
);
