OcrInput Class
Introducing a better code structure with OcrInput
which allows more developer control of OCR.
This structure is the building block on which high-performing OCR applications for C# can be built.
Features include automatic or explicit image optimizations, managed safety from memory leaks, multithreading, multipage documents, OCR to PDF, OCR to HTML, and support for OCR PDF and multipage TIFF files.
Below is an example of how to use the OcrInput
class effectively:
// C# Example demonstrating OcrInput usage
using System;
using SomeOcrLibrary; // Replace with the actual OCR library you're using
namespace OcrExample
{
class Program
{
static void Main(string[] args)
{
// Initialize the OCR input object
OcrInput ocrInput = new OcrInput();
// Add an image to be processed by OCR
// Replace with the path to your image file
ocrInput.AddImage("path/to/your/image.jpg");
// Set options for OCR processing if needed (e.g. language, optimizations)
ocrInput.SetLanguage("eng"); // Setting the language for OCR
// Adding error handling to manage possible exceptions
try
{
// Process the image(s) with OCR
string resultText = ocrInput.Process();
// Output the recognized text
Console.WriteLine("OCR Result: ");
Console.WriteLine(resultText);
}
catch (Exception ex)
{
// Handle exceptions such as file not found or OCR errors
Console.WriteLine($"An error occurred: {ex.Message}");
}
}
}
}
// C# Example demonstrating OcrInput usage
using System;
using SomeOcrLibrary; // Replace with the actual OCR library you're using
namespace OcrExample
{
class Program
{
static void Main(string[] args)
{
// Initialize the OCR input object
OcrInput ocrInput = new OcrInput();
// Add an image to be processed by OCR
// Replace with the path to your image file
ocrInput.AddImage("path/to/your/image.jpg");
// Set options for OCR processing if needed (e.g. language, optimizations)
ocrInput.SetLanguage("eng"); // Setting the language for OCR
// Adding error handling to manage possible exceptions
try
{
// Process the image(s) with OCR
string resultText = ocrInput.Process();
// Output the recognized text
Console.WriteLine("OCR Result: ");
Console.WriteLine(resultText);
}
catch (Exception ex)
{
// Handle exceptions such as file not found or OCR errors
Console.WriteLine($"An error occurred: {ex.Message}");
}
}
}
}

Key Concepts Explained:
- OcrInput Initialization: Instantiates an
OcrInput
object that handles input images for OCR processing. - AddImage Method: Adds an image file to the
OcrInput
object to be processed. This method can be called multiple times to handle multipage documents. - SetLanguage Method: Configures the language to be used by the OCR engine for processing the text.
- Process Method: Executes the OCR operation on the added images and returns the extracted text.
- Error Handling: Protects the application from unexpected issues such as missing files or OCR failures, providing clarity on what errors occurred.
Make sure to replace "SomeOcrLibrary"
with the actual namespace of your OCR library. The sample code is a general guide and may need adaptations based on the specific library or framework you're using.
