QuestPDF.HTML

QuestPDF.HTML is an extension for QuestPDF that allows you to generate PDF from HTML.

QuestPDF currently does not support inserting HTML into a PDF document. This library fills that gap. While it doesn't support the full functionality of HTML and CSS, it covers most common use cases.

Dependencies

• QuestPDF
• HtmlAgilityPack - used for HTML parsing

Installation

dotnet add package QuestPDF.HTML

Usage

Basic Example

Document.Create(container => { container.Page(page => { page.Content().Column(col => { col.Item().HTML(handler => { handler.SetHtml(html); }); }); }); }).GeneratePdf(path);

Custom Image Loading

Recommended: Override the default image loading method for better performance and async support:

col.Item().HTML(handler => { handler.OverloadImgReceivingFunc(GetImgBySrc); handler.SetHtml(html); });

Custom Styles

You can customize text and container styles for specific HTML tags:

handler.SetTextStyleForHtmlElement("div", TextStyle.Default.FontColor(Colors.Grey.Medium)); handler.SetTextStyleForHtmlElement("h1", TextStyle.Default.FontColor(Colors.DeepOrange.Accent4).FontSize(32).Bold()); handler.SetContainerStyleForHtmlElement("table", c => c.Background(Colors.Pink.Lighten5)); handler.SetContainerStyleForHtmlElement("ul", c => c.PaddingVertical(10));

List Padding

Set vertical padding for top-level lists (does not apply to nested lists):

handler.SetListVerticalPadding(40);
