I get several errors on line 379 of CoreGraphicsGraphics.cs:

CrossGraphics/src/CoreGraphicsGraphics.cs(52,52): Error CS1502: The best overloaded method match for `MonoMac.AppKit.NSImage.AsCGImage(ref System.Drawing.RectangleF, MonoMac.AppKit.NSGraphicsContext, MonoMac.Foundation.NSDictionary)' has some invalid arguments (CS1502) (ClockMac)

In addition, I also get

CrossGraphics/src/CoreGraphicsGraphics.cs(22,22): Error CS0535: CrossGraphics.CoreGraphics.CoreGraphicsGraphics' does not implement interface memberCrossGraphics.IGraphics.Clear(CrossGraphics.Color)' (CS0535) (ClockMac)

I'll see if I can figure out how to fix these, though I'm still quite new to Mono.

This is a great library for crossplatform development. I just discovered it reading this article:

I need to render my SVG buttons in Xamarin.Forms (ios/android/osx), but I cannot see the support for SVG on iOS, OSX or Android yet.

I use to create all my assets in SVG because it's the only scalable and crossplatform graphic format. This is how my buttons should look for reference:

You can download the original svg file from my google drive (click on the download button):

Please add support for this. Thanks.

In the DroidGraphics implementation, the font setting has no effect and DrawString always uses whatever the Android typeface and size settings are default.

Your samples are awesome. I would also love to see an opengl sample.

I would like to integrate the basic events such as tap, drag, hold, swipe, etc on the drawn elements. This is fairly easy with WP7 since everything is a UIElement. I saw you have a AndroidCanvasTouchManager class. Do I use this to get the events working on Android? I haven't looked at IOs yet but I am guessing that Android will be the most troublesome to get working...

I love this project! It is very likely to solve a lot of our cross-platform issues.

The one problem I have is that I can't include Graphics.cs in a Visual Studio portable class library as written, since PCLs don't have access to System.Drawing. I've made changes in my personal download of the code, and recommend them to be included in your source, to increase its portability.

1. Separate the Graphics.cs file into Graphics.cs and GraphicsEx.cs by putting all the static extension classes in GraphicsEx.cs, and taking them out of Graphics.cs
2. Alter the Polygon class to use Tuple<Single, Single> instead of PointF to represent internal points.
3. Add a Polygon.PointFs() extension to the polygon class (in GraphicsEx.cs) that converts Polygon.Points (which is now a List<Tuple<Single, Single>>) to a List and returns it.
4. Alter the platform-specific implementation files (e.g. SvgGraphics.cs) so that calls to Polygon.Points instead call the new extension Polygon.PointFs().

At this point, Graphics.cs can be included in the cross-platform library project (a PCL in my case), and GraphicsEx.cs is included in the platform-specific project along with the platform-specific implementation file.

I am willing to submit the text of my code changes, if you want.

Have you considered an implementation for MonoMac? It would probably be quite similar to the MonoTouch one, but the functions are not quite the same.

I might be willing to contribute it, if there's any interest in having it. (But I'm new to github, and not sure quite how I would go about submitting a patch.)
