    }
}

Implementation Guide

We’ll break down the implementation into features, guiding you through each step.

Feature 1: Converting TXT to PDF with Advanced Options

This feature highlights how to convert a text file to PDF format while controlling formatting behaviors like leading spaces and numbering detection.

Set Up Load Options for TXT Conversion

Configure load options using TxtLoadOptions:

import com.groupdocs.conversion.options.load.TxtLoadOptions;
import com.groupdocs.conversion.options.load.TxtLeadingSpacesOptions;

// Create TxtLoadOptions instance.
TxtLoadOptions loadOptions = new TxtLoadOptions();
loadOptions.setLeadingSpacesOptions(TxtLeadingSpacesOptions.ConvertToIndent); // Convert leading spaces to indents.
loadOptions.setDetectNumberingWithWhitespaces(true); // Detect numbering with whitespaces.

Initialize the Converter

Pass the TXT document and load options to the Converter:

import com.groupdocs.conversion.Converter;

// Create converter instance with specific options.
Converter converter = new Converter(inputFile, () -> loadOptions);

Configure PDF Conversion Options

Set up options for converting to PDF using PdfConvertOptions:

import com.groupdocs.conversion.options.convert.PdfConvertOptions;

// Prepare PDF conversion options.
PdfConvertOptions convertOptions = new PdfConvertOptions();

Perform the Conversion

Execute the conversion and save the output PDF:

// Convert TXT to PDF with advanced settings applied.
converter.convert(outputFile, convertOptions);
System.out.println("Conversion complete. Check YOUR_OUTPUT_DIRECTORY for the result.");

Feature 2: Setting Up Load Options for Advanced Text Processing

This feature demonstrates setting up load options specifically for text files that need precise formatting control during conversion.

Configure TxtLoadOptions

Here’s how you can set load options to handle advanced text processing:

TxtLoadOptions txtLoadOptions = new TxtLoadOptions();
txtLoadOptions.setLeadingSpacesOptions(TxtLeadingSpacesOptions.ConvertToIndent);
txtLoadOptions.setDetectNumberingWithWhitespaces(true);

// These options ensure that the PDF conversion respects the original formatting nuances.

Practical Applications

Explore real-world use cases for these advanced features:

  1. Legal Documents: Ensure legal texts maintain their original indentation and numbering formats during conversion.
  2. Technical Manuals: Convert technical manuals with complex lists and spacing into well-formatted PDFs.
  3. Code Documentation: Preserve code structure when converting text files containing source code to PDF format.

These applications demonstrate how GroupDocs.Conversion can be integrated into content management systems or document processing pipelines.

Performance Considerations

Maximize the efficiency of your conversions:

  • Use optimal memory settings for large documents.
  • Regularly update to the latest version of GroupDocs.Conversion for performance improvements.
  • Manage resources effectively, especially when dealing with batch processing tasks.
