High Performance - Generate thousands of pages per second with minimal CPU and memory usage.

Advanced Language Support - Seamlessly create multilingual documents with support for RTL, text shaping, and bi-directional content.

Code-Focused Paradigm

Using C# to design PDF documents leverages powerful control structures like if-statements, for-loops, and methods, enabling dynamic and highly customizable content generation.

It promotes best practices such as modular design and reusability while seamlessly integrating with source control systems for collaboration and versioning.

.Column(column =>
{
    if (Model.Comments != null)
        column.Item().Text(Model.Comments);

    foreach(var item in Model.Items)
       column.Item().Element(c => CreateItem(c, item);
});

void CreateItem(IContainer container, Item item)
{
    container
-       .Background(Colors.Grey.Lighten2)
+       .Background(item.Color)
        .Padding(10)
        .Text(item.Text);
