Extract Text From Image using Java REST API

Discover how to extract text from an image using a Java REST API in this quick‑start tutorial. You’ll learn to retrieve text from images with a Java‑based Cloud SDK and master the OCR customization options offered by the OCRSettingsRecognizeImage class.

Prerequisite

Steps to Extract Text from Picture using Java REST Interface

  1. Import the required classes, models, and utilities from the Aspose.OCR Cloud API
  2. Define the Aspose Cloud client ID and secret for authentication
  3. Create an instance of the RecognizeImageApi using the client ID/secret to establish a secure connection
  4. Load the source image into a byte array
  5. Set the recognition options, such as the language and output result type
  6. Send the image for recognition using PostRecognizeImage and process the response to fetch the stream

These steps define the process of converting image to text using Java REST API. Import the required classes, models, and utilities from the library, define the client ID/secret, and create an instance of the RecognizeImageApi class. Load the image into a byte array, set the recognition options, send the image to the Cloud for processing with the specified options, and process the API response for extracting the text fetched by the API.

Code to Convert Picture Text to Text using Java REST Interface

In this guide we built an image‑to‑text converter as a Java RESTful service. By leveraging OCRSettingsRecognizeImage, you retain full control over preprocessing and recognition—you can choose the language, correct skew, adjust contrast, enable spelling checks, select the recognition mode, and define the desired output type.

Now you’ve mastered extracting text from an image with the Java REST API. If you also need to straighten—or deskew—scanned documents, be sure to check out our comprehensive guide on Deskew Scanned Documents using Java REST API.
