Extract Text From Image using C# REST API

Discover how to extract text from an image using the C# REST API in this concise, step‑by‑step guide. We’ll walk you through pulling text from images with a C# .NET‑based API and the .NET Cloud SDK, and demonstrate how to fine‑tune the OCR process using the OCRSettingsRecognizeImage class.

Prerequisite

Steps to Extract Text from Picture using C# 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 C# 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 C# REST Interface

Throughout this tutorial we crafted a robust image‑to‑text converter powered by a C# REST API. By utilizing OCRSettingsRecognizeImage, you can control every stage of preprocessing and recognition—select the language, fine‑tune skew and contrast, enable spelling correction, choose the desired recognition mode, and define the output type.

You’ve now unlocked the ability to extract text from images using the C# REST API. When you need to straighten (deskew) scanned documents, be sure to check out the companion guide on Deskew Scanned Documents using C# REST API.
