source.getDICOMSignedLongsAsArray¶
Use when: You want to read values from the original incoming message before any mapping changes. If you need the modified message during mapping, use message.getDICOMSignedLongsAsArray.
Signature: source.getDICOMSignedLongsAsArray(nodePath, instance*)
Returns: Number[] result - the first node as a JS Array of JS Numbers that matches the nodePath and instance
Get the result as an array 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 | |
| Integer | instance* | (optional) the match instance to return. Use 1 for the first instance. | 1 |
Example¶
// Example: Retrieve signed long values from a DICOM node as a JavaScript array.
// Get an array of signed longs from the first matching node
var signedLongs = source.getDICOMSignedLongsAsArray(
"0020,0010" // DICOM tag
); // e.g. [1, 0, -1, 0]
// Get signed longs from a specific instance (useful for sequences)
var signedLongsInstance = source.getDICOMSignedLongsAsArray(
"0020,0010", // DICOM tag
2 // instance
);
