Extract Text From Image using C# REST API

Learn how to extract text from an image using the C# REST API with our concise, step‑by‑step tutorial. We’ll guide you through pulling text from pictures via a C# .NET‑based API and the .NET Cloud SDK, and demonstrate how to fine‑tune the OCR workflow 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

In this guide we built a powerful image‑to‑text converter using a C# REST API. With OCRSettingsRecognizeImage, you have full control over every preprocessing and recognition step—pick the language, adjust skew and contrast, enable spelling correction, select the recognition mode, and specify the output format.

Now you’ve mastered extracting text from images with the C# REST API. When it’s time to straighten (deskew) scanned documents, be sure to explore the companion guide on Deskew Scanned Documents using C# REST API.
