Offering comprehensive layout engine powered by concise and discoverable C# Fluent API. ```csharp Document .Create(document => { document.Page(page => { page.Size(PageSizes.Postcard); page.Margin(0.3f, Unit.Inch); page.Header() .Text("Hello PDF!") .FontSize(28) .Bold() .FontColor(Colors.Blue.Darken2); page.Content() .PaddingVertical(8) .Column(column => { column.Spacing(8); column.Item() .Text(Placeholders.LoremIpsum()) .Justify(); column.Item() .AspectRatio(16 / 9f) .Image(Placeholders.Image); }); page.Footer() .AlignCenter() .Text(text => { text.Span("Page "); text.CurrentPageNumber(); }); }); }) .GeneratePdfAndShow(); ``` <img src="https://github.com/user-attachments/assets/ceb5fbbb-843e-46ae-97c1-082a704e8a99" width="300"> <br /> <br /> <br /> ## Please help by giving a star GitHub stars guide developers toward great tools.

It promotes best practices such as modular design and reusability while seamlessly integrating with source control systems for collaboration and versioning. ```csharp .Column(column => { if (Model.Comments != null) column.Item().Text(Model.Comments); foreach(var item in Model.Items) column.Item().Element(c => CreateItem(c, item); }); ``` ```diff void CreateItem(IContainer container, Item item) { container - .Background(Colors.Grey.Lighten2) + .Background(item.Color) .Padding(10) .Text(item.Text); } ``` <br /> ## Multiplatform The library supports all major operating systems, integrates seamlessly with leading IDEs as well as popular cloud platforms and technologies to ensure maximum flexibility. - `Technologies`: modern dotnet, legacy .NET Framework, Docker - `Operating systems`: Windows, Linux, MacOS - `Cloud providers`: Azure, AWS, Google Cloud - `IDE`: Visual Studio, Visual Code, JetBrains Rider, others <br /> ## Perform common PDF operations - Merge documents - Attach files - Extract pages - Encrypt / decrypt - Extend metadata - Limit access - Optimize for Web - Overlay / underlay ```csharp DocumentOperation .LoadFile("input.pdf") .TakePages("1-10") .MergeFile("appendix.pdf", "1-z") // all pages .AddAttachment(new DocumentAttachment { FilePath = "metadata.xml" }) .Encrypt(new Encryption256Bit { OwnerPassword = "mypassword", AllowPrinting = true, AllowContentExtraction = false }) .Save("final-document.pdf"); ``` [](https://www.questpdf.com/concepts/document-operations.html) <br /> ## Let's get started Follow our detailed tutorial, and see how easy it is to produce a fully functional invoice with fewer than 250 lines of C# code.
