PDF data extraction using PdfPig

This is a sample project exploring the capabilities of the PdfPig NuGet package for document data extraction. The project demonstrates how to extract text and data from PDF documents, all withing a Blazor WebAssembly standalone app that runs entirely from the browser.

Web project

The web project is a Blazor WebAssembly standalone app that provides an interactive interface for PDF data extraction. Key features include:

• PdfPig integration: Uses the PdfPig NuGet package to extract text and data from PDF documents
• Modern UI: Built with Microsoft Fluent UI Blazor component library (I wanted to give it a try)
• PDF data selection: Uses the pdf.js JavaScript library to support highlighting regions of the PDF document for data extraction
• Data extraction: Extracts the selected data from the PDF and displays it in a structured format

Tip

Run the app via dotnet run from the /src directory or open the solution in your preferred IDE.

Test project

The test project is just a playground for experimenting with PdfPig features before incorporating them into the web application. It does not include tests for the web app itself. It experiments with various capabilities of the PdfPig, including:

• Basic PDF text extraction
• Block-based content extraction
• Region-specific data extraction
• PDF structure analysis
• Advanced text extraction techniques

Tip

Run the tests via dotnet test from the /tests directory or open the solution in your preferred IDE.

Future plans
