Search And Get Text Page In PDF File

This tutorial explains how to use Aspose.PDF for .NET to search and get text from a specific page in PDF file. The provided C# source code demonstrates the process step by step.

Prerequisites

Before proceeding with the tutorial, make sure you have the following:

  • Basic knowledge of C# programming language.
  • Aspose.PDF for .NET library installed. You can obtain it from the Aspose website or use NuGet to install it in your project.

Step 1: Set up the project

Start by creating a new C# project in your preferred integrated development environment (IDE) and add a reference to the Aspose.PDF for .NET library.

Step 2: Import necessary namespaces

Add the following using directives at the beginning of your C# file to import the required namespaces:

using Aspose.Pdf;
using Aspose.Pdf.Text;

Step 3: Load the PDF document

Set the path to your PDF document directory and load the document using the Document class:

string dataDir = "YOUR DOCUMENT DIRECTORY";
Document pdfDocument = new Document(dataDir + "SearchAndGetTextPage.pdf");

Make sure to replace "YOUR DOCUMENT DIRECTORY" with the actual path to your document directory.

Step 4: Search and extract text from a page

Create a TextFragmentAbsorber object to find all instances of the input search phrase on a specific page:

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("Figure");

Replace "Figure" with the actual text you want to search for.

Step 5: Search on a specific page

Accept the absorber for a specific page of the document:

pdfDocument.Pages.Accept(textFragmentAbsorber);

Step 6: get extracted text fragments

Get the extracted text fragments using the TextFragments property of the TextFragmentAbsorber object:

TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

Step 7: Loop through the text fragments and segments

Loop through the getd text fragments and their segments, and access their properties:

foreach (TextFragment textFragment in textFragmentCollection)
{
	foreach (TextSegment textSegment in textFragment.Segments)
	{
		Console.WriteLine("Text: {0} ", textSegment.Text);
		Console.WriteLine("Position: {0} ", textSegment.Position);
		Console.WriteLine("XIndent: {0} ", textSegment.Position.XIndent);
		Console.WriteLine("YIndent: {0} ", textSegment.Position.YIndent);
		Console.WriteLine("Font - Name: {0}", textSegment.TextState.Font.FontName);
		Console.WriteLine("Font - IsAccessible: {0} ", textSegment.TextState.Font.IsAccessible);
		Console.WriteLine("Font - IsEmbedded: {0} ", textSegment.TextState.Font.IsEmbedded);
		Console.WriteLine("Font - IsSubset: {0} ", textSegment.TextState.Font.IsSubset);
		Console.WriteLine("Font Size: {0} ", textSegment.TextState.FontSize);
		Console.WriteLine("Foreground Color: {0} ", textSegment.TextState.ForegroundColor);
	}
}

You can modify the code within the loop to perform further actions on each text segment.

Sample source code for Search And Get Text Page using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
// Open document
Document pdfDocument = new Document(dataDir + "SearchAndGetTextPage.pdf");
// Create TextAbsorber object to find all instances of the input search phrase
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("Figure");
// Accept the absorber for all the pages
pdfDocument.Pages.Accept(textFragmentAbsorber);
// Get the extracted text fragments
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;
// Loop through the fragments
foreach (TextFragment textFragment in textFragmentCollection)
{
	foreach (TextSegment textSegment in textFragment.Segments)
	{
		Console.WriteLine("Text : {0} ", textSegment.Text);
		Console.WriteLine("Position : {0} ", textSegment.Position);
		Console.WriteLine("XIndent : {0} ", textSegment.Position.XIndent);
		Console.WriteLine("YIndent : {0} ", textSegment.Position.YIndent);
		Console.WriteLine("Font - Name : {0}", textSegment.TextState.Font.FontName);
		Console.WriteLine("Font - IsAccessible : {0} ", textSegment.TextState.Font.IsAccessible);
		Console.WriteLine("Font - IsEmbedded : {0} ", textSegment.TextState.Font.IsEmbedded);
		Console.WriteLine("Font - IsSubset : {0} ", textSegment.TextState.Font.IsSubset);
		Console.WriteLine("Font Size : {0} ", textSegment.TextState.FontSize);
		Console.WriteLine("Foreground Color : {0} ", textSegment.TextState.ForegroundColor);
	}
}

FAQ’s

Q: What is the purpose of the “Search And Get Text Page” tutorial?

A: The “Search And Get Text Page” tutorial is designed to illustrate how to use the Aspose.PDF library for .NET to search for and retrieve text from a specific page within a PDF file. The tutorial provides detailed instructions and sample C# code to demonstrate the process.

Q: How does this tutorial help in extracting text from a specific page in a PDF document?

A: This tutorial guides you through the process of extracting text from a particular page of a PDF document using the Aspose.PDF library. It outlines the necessary steps and provides C# code to search for a specified text phrase on the selected page and retrieve associated text segments.

Q: What are the prerequisites for following this tutorial?

A: Before starting this tutorial, you should have a basic understanding of the C# programming language. Additionally, you need to have the Aspose.PDF for .NET library installed. You can obtain it from the Aspose website or use NuGet to integrate it into your project.

Q: How do I set up my project to follow this tutorial?

A: To get started, create a new C# project in your preferred integrated development environment (IDE) and add a reference to the Aspose.PDF for .NET library. This will enable you to utilize the library’s capabilities in your project.

Q: Can I search for text on a specific page of the PDF document?

A: Yes, this tutorial demonstrates how to search for text on a specific page of a PDF document. It involves using the TextFragmentAbsorber class to locate instances of a particular text phrase on the chosen page.

Q: How do I access the extracted text segments from the specific page?

A: After searching for the text on the designated page, you can access the extracted text segments using the TextSegments property of the TextFragment object. This property provides access to a collection of TextSegment objects that contain the extracted text and related information.
