# Position Extraction

[Java SDK](/v1/docs/position-extraction#java-sdk) [.NET SDK](/v1/docs/position-extraction#net-sdk) [REST API](/v1/docs/position-extraction#rest-api) [APEX SDK](/v1/docs/position-extraction#apex-sdk)

## Java SDK

To download the full code sample see our [Code Share](https://community.onespan.com/documentation/onespan-sign/codeshare/position-extraction-java-sdk/) site. For information on using Position Extraction with Conditional Fields, see [Position Extraction + Conditional Fields](https://community.onespan.com/documentation/codeshare/position-extraction-conditional-fields).

The Position Extraction feature ensures that the exact position and size of a field or signature in an uploaded PDF file are automatically retained in OneSpan Sign.

The following sample code shows you how to edit the document block object with position extraction.

If you need a comparison to the basic object creation procedure, or if this is the first time creating a transaction, see [](https://developer.esignlive.com/guides/quick-start/creating-and-sending-a-package-net/)[Creating and Sending a Transaction](/v1/docs/creating-and-sending-a-transaction#net-sdk).

```java
.withDocument(newDocumentWithName("First Document")
    .fromFile("DOC_FILE_PATH")
    .enableExtraction()
    .withSignature(signatureFor("john.smith@email.com")
        .withName("sig1")
        .withPositionExtracted()
    )
)
```

Ensure that you have the enableExtraction() call set at the document level and that your PDF document contains a field named sig1. Otherwise, an error will be thrown.

### Results

Here is an example of what you can expect to see once you have run your code.

The Position Extraction feature ensures that the exact position and size of a field or signature in an uploaded PDF file are automatically retained in OneSpan Sign.

The following sample code shows you how to edit the document block object with position extraction.

If you need a comparison to the basic object creation procedure, or if this is the first time creating a transaction, see [](https://developer.esignlive.com/guides/quick-start/creating-and-sending-a-package-net/)[Creating and Sending a Transaction](/v1/docs/creating-and-sending-a-transaction#net-sdk).

```plaintext
// Prepare Documents Blob
String document1Name = 'Sample_Position_Extraction';
StaticResource sr = [SELECT Id, Body FROM StaticResource WHERE Name = 'test_position_extraction' LIMIT 1];
Map<String, Blob> documentBlobMap = new Map<String, Blob>();
documentBlobMap.put(document1Name, sr.Body);

// Create Document Metadata
ESignLiveAPIObjects.Document document1 = new ESignLiveAPIObjects.Document();
document1.name = document1Name;
document1.id = document1Name;
document1.extract = true; // document level extraction: true

// Create Approval Metadata
ESignLiveAPIObjects.Approval approval1 = new ESignLiveAPIObjects.Approval();
approval1.role = roleId1;
approval1.id = 'approval1';

// Create Field Metadata
ESignLiveAPIObjects.Field field1 = new ESignLiveAPIObjects.Field();
field1.id = 'signature1';
field1.extract = true;
field1.name = 'sig1'; // match pdf field property name
field1.type = 'SIGNATURE';
field1.subtype = 'FULLNAME';

// Assign Fields to Approval
approval1.fields = new List<ESignLiveAPIObjects.Field>{field1};

// Assign Approvals to Document
document1.approvals = new List<ESignLiveAPIObjects.Approval>{approval1};

// Add Document to Package
pkg.documents = new List<ESignLiveAPIObjects.Document>{document1}; // add document
```

Ensure that you have the enableExtraction() call set at the document level and that your PDF document contains a field named sig1. Otherwise, an error will be thrown.
