How Tos

The samples and documentation should get you quickly up and running with PDF Extract capabilities in the PDFServices SDK including:

  • Extracting PDF as JSON: the content, structure & renditions of table and figure elements along with Character Bounding Boxes

For code examples illustrating other PDF actions including those below, see the PDFServices SDK :

  • Creating a PDF from multiple formats, including HTML, Microsoft Office documents, and text files
  • Exporting a PDF to other formats or an image
  • Combining entire PDFs or specified page ranges
  • Using OCR to make a PDF file searchable with a custom locale
  • Compress PDFs with compression level and Linearize PDFs
  • Protect PDFs with password(s) and Remove password protection from PDFs
  • Common page operations, including inserting, replacing, deleting, reordering, and rotating
  • Splitting PDFs into multiple files

How It Works#

PDF Extract uses AI/ML technology to identify and categorize the various objects within documents – such as paragraphs, lists, headings, tables, and images – and extract the text, formatting, and associated document structural information which is then delivered in a resulting JSON file. Extracted table data can optionally be delivered within .CSV or .XLSX files, and extracted images are delivered as .PNG files. For additional information, please refer to PDF Extract API white paper

Runtime in-memory authentication#

The SDK supports providing the authentication credentials at runtime. Doing so allows fetching the credentials from a secret server during runtime instead of storing them in a file. Please refer the following samples for details.

Custom timeout configuration#

The APIs use inferred timeout properties and provide defaults. However, the SDK supports custom timeouts for the API calls. You can tailor the timeout settings for your environment and network speed. In addition to the details below, you can refer to working code samples:

Java timeout configuration#

Available properties:

  • connectTimeout: Default: 2000. The maximum allowed time in milliseconds for creating an initial HTTPS connection.
  • socketTimeout: Default: 10000. The maximum allowed time in milliseconds between two successive HTTP response packets.

Override the timeout properties via a custom ClientConfig class:

Copied to your clipboard
1ClientConfig clientConfig = ClientConfig.builder()
2 .withConnectTimeout(3000)
3 .withSocketTimeout(20000)
4 .build();

.NET timeout configuration#

Available properties:

  • timeout: Default: 400000. The maximum allowed time in milliseconds for establishing a connection, sending a request, and getting a response.
  • readWriteTimeout: Default: 10000. The maximum allowed time in milliseconds to read or write data after connection is established.

Override the timeout properties via a custom ClientConfig class:

Copied to your clipboard
1ClientConfig clientConfig = ClientConfig.ConfigBuilder()
2 .timeout(500000)
3 .readWriteTimeout(15000)
4 .Build();

Node.js timeout configuration#

Available properties:

  • connectTimeout: Default: 10000. The maximum allowed time in milliseconds for creating an initial HTTPS connection.
  • readTimeout: Default: 10000. The maximum allowed time in milliseconds between two successive HTTP response packets.

Override the timeout properties via a custom ClientConfig class:

Copied to your clipboard
1const clientConfig = PDFServicesSdk.ClientConfig
2 .clientConfigBuilder()
3 .withConnectTimeout(15000)
4 .withReadTimeout(15000)
5 .build();

Python timeout configuration#

Available properties:

  • connectTimeout: Default: 4000. The number of milliseconds Requests will wait for the client to establish a connection to Server.
  • readTimeout: Default: 10000. The number of milliseconds the client will wait for the server to send a response.

Override the timeout properties via a custom ClientConfig class:

Copied to your clipboard
1client_config = ClientConfig.builder()
2 .with_connect_timeout(10000)
3 .with_read_timeout(40000)
4 .build()
