PdfSharp.Xamarin.Forms

PdfSharp.Xamarin.Forms is a Xamarin.Forms library for converting any Xamarin.Forms UI into PDF. It uses PdfSharp, which is a partial port of PdfSharpCore.

Supported Platforms

• UWP
• Android
• iOS

Screenshots (see all)

Usage

• Init : For each platform you need to init seperately: PdfSharp.Xamarin.Forms.{Platform}.Platform.Init()
• Generate : var pdf = PDFManager.GeneratePDFFromView(yourView)
• Save : DependencyService.Get<IPdfSave>().Save(pdf, "pdfName.pdf")

Features

• Custom Fonts (You should provide Font Types and font files via IPDFHandler)
• Image rendering
• Custom renderer ( You can write your own renderer for your customView)
• Paper size & orientation support
• Do not render option : by using pdf:PdfRendererAttributes.ShouldRender="False" you can ignore that view in PDF

Limitations

• Images renders only Jpeg format (It converts PNG to JPEG automatically)
• ListView does not renders automatically. You should write a renderer.

ListView Rendering

• Due ListView Cell is not accesible from parent, you should implement a PdfListViewRendererDelegate for the ListView.

  <ContentPage  xmlns:pdf="clr-namespace:PdfSharp.Xamarin.Forms;assembly=PdfSharp.Xamarin.Forms">
    <ListView pdf:ListRendererDelegate="{StaticResource YourRendererDelegate}" .../>
  </ContentPage>

Renderer:

    public class PDFSampleListRendererDelegate: PdfListViewRendererDelegate
    {
        public override void DrawCell(ListView listView, int section, int row, XGraphics page, XRect bounds, double scaleFactor)
        {
            base.DrawCell(listView, section, row, page, bounds, scaleFactor);
        }

        public override void DrawFooter(ListView listView, int section, XGraphics page, XRect bounds, double scaleFactor)
        {
            base.DrawFooter(listView, section, page, bounds, scaleFactor);
        }

        public override double GetFooterHeight(ListView listView, int section)
        {
            return base.GetFooterHeight(listView, section);
        }
    }

Custom PDF Renderer

Its possible to write your own renderer, it will use it while renderering your View.

Register : PDFManager.RegisterRenderer(typeof(Label), typeof(PDFCustomLabelRenderer))

Render:

    public class PDFCustomLabelRenderer : PdfRendererBase<Label>
    {
        public override void CreatePDFLayout(XGraphics page, Label label, XRect bounds, double scaleFactor)
        {
            XFont font = new XFont(label.FontFamily ?? GlobalFontSettings.FontResolver.DefaultFontName, label.FontSize * scaleFactor);
            Color textColor = label.TextColor != default(Color) ? label.TextColor : Color.Black;

            if (label.BackgroundColor != default(Color))
                page.DrawRectangle(label.BackgroundColor.ToXBrush(), bounds);

            if (!string.IsNullOrEmpty(label.Text))
                page.DrawString(label.Text, font, textColor.ToXBrush(), bounds,
                    new XStringFormat()
                    {
                        Alignment = label.HorizontalTextAlignment.ToXStringAlignment(),
                        LineAlignment = label.VerticalTextAlignment.ToXLineAlignment(),
                    });
        }
    }
