tesseract-ocrHow do I use Tesseract OCR in a C# application?
Using Tesseract OCR in a C# application is relatively straightforward. First, you need to install the Tesseract NuGet package. To do this, open the NuGet Package Manager Console in Visual Studio and run the following command:
Install-Package Tesseract
Once the package is installed, you can use the TesseractEngine class to recognize text from an image. For example:
using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
{
using (var img = Pix.LoadFromFile(@"./image.png"))
{
using (var page = engine.Process(img))
{
var text = page.GetText();
Console.WriteLine("Recognized text: \n\n{0}", text);
}
}
}
// Output: Recognized text:
//
// This is some example text
The code above does the following:
- Creates a new TesseractEngine instance, specifying the path to the language data, the language to use, and the engine mode.
- Loads an image from a file.
- Processes the image with the engine.
- Gets the recognized text from the page.
- Writes the text to the console.
For more information, please refer to the Tesseract documentation.
