PdfSharpCore

PdfSharpCore is a partial port of PdfSharp.Xamarin for .NET Standard Additionally MigraDoc has been ported as well (from version 1.32). Images have been implemented with ImageSharp, which is still in Alpha. They State on their readme that it is still in Alpha status and shouldn't be used in productive environments. Since I didn't find any good alternatives it's still used.

ImageSharp being Alpha isn't a big issue either since this code isn't by far done yet. So please chime in ;)

PdfSharp.Xamarin is a partial port of PdfSharp for iOS and Android using Xamarin, it allows for creation and modification of PDF files.

Example project

There was an example project here.
I've removed it from this project, and put it into a separate solution. You can find it here.
There's a default font-resolver in FontResolver.cs.
It should work on Windows, Linux, OSX and Azure.
Some limitations apply.
See open issues.

Example usage

//See the "Example" Project for a MigraDoc example
static void Main(string[] args)
{
    GlobalFontSettings.FontResolver = new FontResolver();

var document = new PdfDocument();
var page = document.AddPage();
var gfx = XGraphics.FromPdfPage(page);
var font = new XFont("OpenSans", 20, XFontStyle.Bold);

gfx.DrawString("Hello World!", font, XBrushes.Black, new XRect(20, 20, page.Width, page.Height), XStringFormats.Center);

document.Save("test.pdf");

}

//This implementation is obviously not very good --> Though it should be enough for everyone to implement their own. public class FontResolver : IFontResolver { public byte[] GetFont(string faceName) { using(var ms = new MemoryStream()) { using(var fs = File.Open(faceName, FileMode.Open)) { fs.CopyTo(ms); ms.Position = 0; return ms.ToArray(); } } } public FontResolverInfo ResolveTypeface(string familyName, bool isBold, bool isItalic) { if (familyName.Equals("OpenSans", StringComparison.CurrentCultureIgnoreCase)) { if (isBold && isItalic) { return new FontResolverInfo("OpenSans-BoldItalic.ttf"); } else if (isBold) { return new FontResolverInfo("OpenSans-Bold.ttf"); } else if (isItalic) { return new FontResolverInfo("OpenSans-Italic.ttf"); } else { return new FontResolverInfo("OpenSans-Regular.ttf"); } } return null; } } }
