Matios.Pdf 0.1.0

Matios.Pdf

Generate .pdf files (PDF / ISO 32000) from .NET with an own implementation and zero external dependencies — only System.*. Runs on .NET 10.

Features

• Text — the 14 standard fonts, plus embedded TrueType fonts with full Unicode (Type0 / Identity-H + ToUnicode). Measurement and left/center/right alignment.
• Vector graphics — lines, rectangles, polygons, circles/ellipses, Bézier curves, graphics state, DeviceRGB color.
• Images — JPEG (/DCTDecode) and PNG, including transparency via a soft mask.
• Compression — content streams are compressed with FlateDecode by default.
• Metadata — title, author, subject, keywords and dates.
• Layout engine — wrapping paragraphs, a flowing document with automatic pagination and repeating headers/footers, and tables whose cells wrap and whose rows paginate.

Coordinates are top-left based (Y grows down), like most drawing APIs.

Quick start

Low-level drawing:

using Matios.Pdf;

using var doc = new PdfDocument();
var g = doc.Pages.Add(PdfPageSize.A4).Graphics;

g.DrawString("Invoice", PdfFont.HelveticaBold, 24, 72, 80, PdfColor.FromRgb(20, 40, 120));
g.DrawLine(72, 100, 523, 100, PdfColor.Gray, 1.5);
g.DrawRectangle(72, 120, 200, 60, stroke: true, fill: true,
    strokeColor: PdfColor.Blue, fillColor: PdfColor.FromRgb(220, 230, 250));

doc.Save("invoice.pdf");

Embed a font for full Unicode:

var font = PdfFont.FromFile(@"C:\Windows\Fonts\arial.ttf");
g.DrawString("Canción — €50 — ñandú", font, 14, 72, 160);

High-level layout (flowing document with automatic pagination and a table):

using var doc = new PdfDocument();
var flow = new PdfFlow(doc, PdfPageSize.A4, margin: 56);

flow.Header(40, a => a.Graphics.DrawString("Report", PdfFont.HelveticaBold, 13, a.X, a.Y + 14));
flow.Footer(28, a => a.Graphics.DrawString(
    $"Page {a.PageNumber} of {a.TotalPages}", PdfFont.Helvetica, 9, a.X + a.Width, a.Y + 14, PdfTextAlign.Right));

flow.Paragraph("A long paragraph that wraps to the column width and paginates on its own…",
    PdfFont.Helvetica, 12, leading: 16, spacingAfter: 10);

flow.Table(t =>
{
    t.ProportionalColumns(6, 1, 2, 2);
    t.Align(PdfTextAlign.Left, PdfTextAlign.Right, PdfTextAlign.Right, PdfTextAlign.Right);
    t.HeaderRow("Description", "Qty", "Unit", "Total");
    t.Row("Matios.Pdf license", "1", "480.00", "480.00");
});

flow.Save("report.pdf");
