The latest release of GroupDocs.Parser for .NET 24.7 (DLLs only) is here! This package offers a refined set of features designed to equip developers building C# and VB.NET applications with dynamic document parsing capabilities.
OCR-based Text Extraction in Images and PDFs
Use the built-in OCR functionality in this C# document parsing API release to extract text from scanned documents and images immaculately within your .NET Framework projects. The following code examples illustrates extracting text from PDFs and images respectively.
// Create an instance of Parser class
using (Parser parser = new Parser("scanned.pdf"))
{
// Create an instance of TextOptions to use OCR
TextOptions options = new TextOptions(false, true);
// Extract a text using OCR
using(TextReader reader = parser.GetText(options))
{
// Print a text or 'not supported' message
Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
}
}
// Create an instance of Parser class
using (Parser parser = new Parser("scanned.jpg"))
{
// Extract a text using OCR
using(TextReader reader = parser.GetText())
{
// Print a text or 'not supported' message
Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
}
}

Empowered OCR Functionality
Create full-featured document parsing solutions and utilize spell-checking alongside OCR for better text accuracy. Check out the code sample shared below to learn how to integrate this functionality into your C# applications.
// Create an instance of Parser class
using (Parser parser = new Parser("scanned.pdf"))
{
// Create an instance of TextOptions to use OCR and spell checker
TextOptions options = new TextOptions(false, true, new OcrOptions(null, null, true));
// Extract a text using OCR
using(TextReader reader = parser.GetText(options))
{
// Print a text or 'not supported' message
Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
}
}

Preview Document Pages
GroupDocs.Parser for .NET now makes it possible to generate high-fidelity page previews to quickly overview the document content, as showcased in this code sample.
// Create an instance of Parser class
using (Parser parser = new Parser("document.pdf"))
{
// Get the page count
int pageCount = parser.GetDocumentInfo().PageCount;
// Iterate over the document pages
for (int i = 0; i < pageCount; i++)
{
// Generate the preview of the document page
using (Stream stream = parser.GetPagePreview(i))
{
// Save the preview to the PNG file
using (Stream fileStream = File.Create($"page_{i}.png"))
{
stream.CopyTo(fileStream);
}
}
}
}

With this release of the document indexing API, you can conveniently extract barcodes from individual pages within your multipage TIFF files. This code example highlights the feature usage.
// Create an instance of Parser class
using (Parser parser = new Parser(Constants.SamplePdfWithBarcodes))
{
// Check if the barcodes extraction is supported
if (!parser.Features.Barcodes)
{
Console.WriteLine("Document doesn't support barcodes extraction.");
return;
}
// Extract barcodes from the second page.
IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes(1);
// Iterate over barcodes
foreach (PageBarcodeArea barcode in barcodes)
{
// Print the page index
Console.WriteLine("Page: " + barcode.Page.Index.ToString());
// Print the barcode value
Console.WriteLine("Value: " + barcode.Value);
}
}
