Invoice Splitter API Java

The Java OCR SDK supports the Invoice Splitter API.

Using this sample, we are going to illustrate how to detect the pages of multiple invoices within the same document.

Quick-Start

⚠️ Important: This API only works asynchronously, which means that documents have to be sent and retrieved in a specific way:

import com.mindee.MindeeClient;
import com.mindee.input.LocalInputSource;
import com.mindee.parsing.common.AsyncPredictResponse;
import com.mindee.parsing.common.Job;
import com.mindee.parsing.common.Document;
import com.mindee.product.invoicesplitter.InvoiceSplitterV1;
import java.io.File;
import java.io.IOException;
import java.util.Optional;

public class SimpleMindeeClient {

  public static void main(String[] args) throws IOException, InterruptedException {
    String apiKey = "my-api-key";
    String filePath = "/path/to/the/file.ext";

    // Init a new client
    MindeeClient mindeeClient = new MindeeClient(apiKey);

    // Load a file from disk
    LocalInputSource inputSource = new LocalInputSource(new File(filePath));

    // Parse the file asynchronously
    AsyncPredictResponse<InvoiceSplitterV1> response = mindeeClient.enqueueAndParse(
      InvoiceSplitterV1.class,
      inputSource
    );

    // Print a summary of the response
    System.out.println(response.toString());

    // Print a summary of the predictions
//  System.out.println(response.getDocumentObj().toString());

    // Print the document-level predictions
//    System.out.println(response.getDocumentObj().getInference().getPrediction().toString());

    // Print the page-level predictions
//    response.getDocumentObj().getInference().getPages().forEach(
//        page -> System.out.println(page.toString())
//    );
  }
}

Field Types

Specific Fields

Page Indexes

List of page group indexes.

A PageIndexes implements the following attributes:

pageIndexes (List<Integer>): List of indexes of the pages of a single invoice.
confidence (Double): The confidence of the prediction.

Attributes

The following fields are extracted for Invoice Splitter V1:

Invoice Page Groups

invoicePageGroups (List<invoicePageGroups>): List of page indexes that belong to the same invoice in the PDF.

for (invoicePageGroupsElem : result.getDocument().getInference().getPrediction().getInvoicePageGroups())
{
  System.out.println(invoicePageGroupsElem);
}
