SharpVectors - SVG# Reloaded: SVG DOM and Rendering in C# for the .Net.

Project Description

The Scalable Vector Graphics (SVG) is an XML-based standard file format for creating graphics on the web, and is supported by most modern browsers. This project provides a C# library for parsing, converting and viewing the SVG files in WPF applications.

The Scalable Vector Graphics (SVG) is now natively supported in most internet browsers, including the IE 9. With the HTML5, the use of the SVG as graphics format on the web is increasing.

For .NET application developers, there is currently no library complete enough to handle SVG files. Even the commercial tools are either not available or not complete enough to handle most uses of the SVG in Windows Presentation Foundation (WPF) applications. The project does not aim to provide a complete implementation of the SVG file format, but will support the features required in an average graphics application.

The SVG specification is available in HTML format or the PDF format.

Features and Uses

In general, the following features are implemented:

• Parsing of the SVG files to create the SVG DOM
• SVG to XAML conversion
• A small runtime library to handle font URI, embedded images and others when using the XAML files directly from disk.
• An optimized XAML output.
• A simple and basic SVG viewer (an advanced viewer is planned).
• Interaction with the conversion process (by a visitor pattern) to allow for custom hyper-link implementations, font substitutions etc.

NOTE: Only Geometry/Drawing level elements are exported, which will not work with Silverlight. See the Documentation section for more information on the features.

Installation

The SharpVectors library targets the following frameworks

• .NET Framework, Version 4.0
• .NET Framework, Version 4.5
• .NET Framework, Version 4.6
• .NET Framework, Version 4.7
• .NET Framework, Version 4.8
• .NET Standard, Version 2.1
• .NET Core, Version 3.1
• .NET 6.0 ~ .NET 8.0

The library can be used in WPF and Windows Forms applications.

For the Library

The library can be downloaded from the following sources

• NuGet (WPF Only Package), Version 1.8.4 - SharpVectors.Wpf.
• NuGet (Full Package - WPF/GDI++), Version 1.8.4 - SharpVectors.
• NuGet (Full Package - WPF/GDI++), Version 1.8.4 - SharpVectors.Reloaded.
• GitHub Releases Page, Version 1.8.4.

• The SharpVectors.Reloaded package is the same as the SharpVectors, which is the recommended package if you need the full package.
• The SharpVectors.Reloaded name was used for the Nuget package at the time the SharpVectors package name was not available.
• The SharpVectors.Reloaded package name will be retired in Version 2.0.
• The SharpVectors.Wpf is the recommended package, for WPF only application.
• As outlined in the roadmap, other packages such as the SharpVectors.Gdi for the GDI+, will be available as the renderers mature.

Documentation

An introduction and a tutorial with sample are available. See the Documentation section for more information.

Sample Applications

The library includes a number of sample application for both WPF and GDI+. Here are some of them:

WPF Test Application

This is an application for browsing directory (recursively) of SVG files.

WPF W3C Test Suite

This is an application for viewing the W3C Test Suite compliant results. It has two panes: top and bottom. The top pane is the generated WPF output, the bottom pane is the W3C expected output image. By the test results, this is the most complete SVG reader for WPF!

GDI+ W3C Test Suite

This is an application for viewing the W3C Test Suite compliant results. It has two panes: top and bottom. The top pane is the generated GDI+ output, the bottom pane is the W3C expected output image.

Tutorial Samples

A number of tutorial samples are available in the TutorialSamples folder.

Get rid of System.Web assembly

Currently there are 2 references to system.web assembly :

in SharpVectors.Css (not used, I have removed it without errors)
in SharpVectors.Rendering.Wpf (in WpfRenderingBase, lines 88 and 133)
 
It's a drawback because if we want to use this library in .NET 4 project, we can't use NET 4 Client Profile (or 3.5 Client Profile) which targets end-user systems because of this dependency.
 
There are 2 solutions :
Migrate to .NET 4 and use WebUtility.HtmlDecode : http://msdn.microsoft.com/en-us/library/ee388355.aspx (not easy in short-term)
Stay in 3.5 and replace uses of HttpUtility.HtmlDecode by a home-made function.
 
FYI, I've got a sample Strings utility class which exposes Html & Url related methods against .NET 2 : http://pastebin.com/i6maWnUn
Feel free to copy it or create a simpler code based on it.

Memory leak

I think, there is a memory leak when I use FileSvgReader.Read method.

I have downloaded the SharpVectors converter application, and I have used the normal file converter.
The application takes ~30Mb-es after start. My svg file is about 300kb and when I click the "convert" button, the memory usage starts to increase.
When it is ready the application memory usage is ~60Mb (!!!) and do not decrease.

I have tried it with a 11Mb svg file, and the memory usage is ~700Mb after the successful convert.

It is the same situation in my applicaion which uses only the FileSvgReader.Read method.

Please check this situation!

Thank you!
Best Reagards,
Gergely

ImageSvgConverter : write output to stream

Hi,
 
I'm using ImageSvgConverter to convert svg files (inside a MemoryStream).
It seems that we can convert a stream to an image file, but not to an other stream.
 
Can you add an overload for the Convert function to allow converters to work from/to streams ?
 
Thanks.

GDI broken?

Been looking at the GDI renderer and hit a problem so tried with the samples and they give the same error.

Inheritance security rules violated while overriding member: 'SharpVectors.Renderers.Gdi.GdiGraphicsRenderer.get_Window()'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

In GdiTextSVGViewer sample the error is when creating the SvgPictureBox control.

Limitation of conversion to 640x480

I have tried out SharpVectors recently because I was in need to display SVG images within a WPF application.
 
The bounding box of my SVG images is quite large around 2048x2048. After using the conversion API (SvgFileReader.Read(stream)) to convert my SVG into a DrawingGroup, I found out that the image is cut off, only part of the original SVG visible.
 
I examined the source code I located a few spots with hard coded dimensions of 640x480 in the converters and runtime assemblies, without the possibility to adjust the rendersize in any way.
 
So here comes my question: What is the reason for that?
 
BTW: I increased the dimensions by modifing the source and everything worked fine afterwards.

SvgAnimatedNumber Bug

There is a bug in SvgAnimatedNumbers.cs:
public SvgAnimatedNumber(string str)
{
baseVal = SvgNumber.ParseNumber(str);
animVal = baseVal;
}

This is a problem on systems with other decimal separator then ".". I think this is the fix:
public SvgAnimatedNumber(string str)
{
baseVal = Double.Parse(str, SvgNumber.Format);
animVal = baseVal;
}

I checked all double.Parse() code lines. They look to be correct.

Problem rendering gradient fills

I have a problem with SharpVectors rendering gradient fills.
 
Here are three files that reproduce the problem:
 
http://www.codefurnace.com/pipe1.svg
http://www.codefurnace.com/pipe3.svg
http://www.codefurnace.com/pipe4.svg
 
You may be able to see, on pipe1.svg the gradient fill is rendered 90 degrees sideways. On pipe4.svg the radius gradient isn't even rendered. I'm using the GDI renderer in a WinForms application.
 
Any suggestions on how to fix it would be very helpful, or if I'm doing something wrong in the WinForms app, I'm keeping the SVG files in a resource file compiled in the application, and loading them from a stream.
 
Thanks...

Impossible to Scale and Print after render of GdiGraphicsRenderer. Raster is NULL or Empty

Hello,

We try to print the result of render action but the printing flow that is just created seems to be more larger than the paper size. So we want to adjust the printing area by a pretty common solution that is used with System.Drawing.Graphics component by DrawImage.
Rectangle printableFinal = new Rectangle(0, 0, 500, 500);
g.DrawImage(imgageToPrint, printableFinal);

Here is the end of our source code that provide a flow to be print :
[...]
// Définit l'évènement d'impression
printDocument.PrintPage += (sender, e) => PrintDOC(sender, e, wpfWindow);

       // Démarre l’impression
        printDocument.Print();
  }

    protected void PrintDOC(object sender, PrintPageEventArgs printEvtArgs, WpfSvgWindow wpfWindow)
    {
        Graphics g = printEvtArgs.Graphics;
        GdiGraphicsRenderer gdiRenderer = (GdiGraphicsRenderer)wpfWindow.Renderer;
        
        gdiRenderer.GraphicsWrapper = GdiGraphicsWrapper.FromGraphics(g, false);
        gdiRenderer.Render(wpfWindow.Document as SvgDocument);

// NOT WORKING CODE - Because "gdiRender.RasterImage" is NULL !!!
// Rectangle printableFinal = new Rectangle(0, 0, 500, 500);
// Bitmap imgageToPrint = gdiRenderer.RasterImage;
// imgageToPrintAP = gdiRenderer.GraphicsWrapper.IdMapRaster;
// g.DrawImage(imgageToPrintAP, printableFinal);
}

Printing action is working, our wpfWindow is perfectly print on the paper but element is to huge to fit on page. So we are trying to redure this element during the rendering process or just after to make the element be scale juste before the printing process.

We notice some problems on the component but we don't know if it is a bug or a bad use of it :

"gdiRenderer.RasterImage" provide a NULL value just after "gdiRenderer.Render(..." instruction
"gdiRenderer.IdMapRaster" provide a 180x180 empty image !

We need to catch the result flow of "gdiRenderer.Render" action.
How can we do that ?

Thanks for helping us.

ExtendedHttpWebRequest Issue

Hi there,
 
I have seen that you are using your ExtendedHttpWebRequest class to handle some features. I have a problem with this class, because it has broken my code. I have written the small example to explain my problem:
 
class Program
{
static void Main(string[] args)
{
// Everything works ok, here
{
WebRequest request = WebRequest.Create("http://google.com");
var httpRequest = (HttpWebRequest)request;
}

 
// Css document object is created
CssXmlDocument doc = new CssXmlDocument();

 
// InvalidCastException appears here
{
WebRequest request = WebRequest.Create("http://google.com");
var httpRequest = (HttpWebRequest)request;
}
}
}

 
This problem occurs because in CssXmlDocument there is following code:
SharpVectors.Net.ExtendedHttpWebRequest.Register();
SharpVectors.Net.DataWebRequest.Register();

 
I believe it is a bug, because HTTP and HTTPS schemes handling is implemented in .NET and in MSDN it is written: "The HttpWebRequest class is registered to service requests for HTTP and HTTPS schemes by default. Attempts to register a different WebRequest descendant for these schemes will fail.". This is certainly false, nevertheless these two schemes should not be overriden.

Considering the viewbox in the SVG

Hello,

I'm trying to show an SVG within certain bounds. But depending on the SVG the icon should sometimes appear smaller than other icons - only the SVG itself knows how large it actually is. My goal is to render SVGs onto the face of buttons, so the button defines the maximum size of the SVG only. I would expect that the SVG would size according to the viewbox specified in the SVG.

An example:
The viewbox attribute in the SVG is a rectangle (x=-10, y=-10, width=40, height=40).
Graphical elements are placed inside a region (x=0, y=0, width=20, height=20).
I would expect that the finally rendered image contains a margin around the actual drawing that is 50% of the width of the drawing on the left and right side and 50% of the height of the drawing on the top and buttom side.

Is there a way to accomplish that? Your library is really nice and I've been using it for some time know, but this detail is a real showstopper (for me) at the moment :-/

It would be great, if you could give me a hint how I can get it working correctly.

Thank you very much!

Ravenpride

when the file contains for example transform="translate (10, 10), scale (1.1, 1.1), translate (-10, -10)" (yes thats right: with spaces between translate and scale and its adjoining parentheses) then we got an exception. if you eliminate the first space (translate(10, 10) instead of translate (10, 10)) the it no longer throws an exception but just does nothing - transform-wise)
 
If you need examples for that - please let me know
 
Regards,
 
Juergen Key

SvgFontUri in xaml + SvgStopElement

Hi,

Created xaml file contains wrong font path. This code

<GlyphRun.GlyphTypeface>

</GlyphRun.GlyphTypeface>
throws an exception "A Dos path must be rooted, for example, 'c:'", because separator char must be '/' or "\".

source file SharpVectors.Converters.XmlXamlWriter ln 503:

string fontUri = temp.ToLower();
fontUri = fontUri.Replace(_windowsDir, _windowsPath);
my bugfix:

string fontUri = temp.ToLower();
fontUri = fontUri.Replace(_windowsDir, _windowsPath).Replace('\', '/');
But I'm not sure that's good enough.

I'm used this svg sample for testing.

BTW, You can't create xaml from this file, because some stop-element.offset in SVG is not defined, and code in SharpVectorModel\Fills\SvgStopElements.cs

public ISvgAnimatedNumber Offset
{
get
{
string attr = GetAttribute("offset").Trim();
if (attr.EndsWith("%"))
{
attr = attr.TrimEnd(new char[1]{'%'});
}
else
{
double tmp = SvgNumber.ParseNumber(attr) * 100;
attr = tmp.ToString(SvgNumber.Format);
}

    return new SvgAnimatedNumber(attr);
}

}
throws an exception on SvgNumber.ParseNumber(attr), because attr is empty.

In code

public static double ParseNumber(string str)
{
try
{
return Double.Parse(str, SvgNumber.Format);
}
catch (Exception e)
{
throw new DomException(DomExceptionType.SyntaxErr,
"Input string was not in a correct format: " + str, e);
}
}
I change
return Double.Parse(str, SvgNumber.Format);

to
return string.IsNullOrEmpty(str) ? 0 : Double.Parse(str, SvgNumber.Format);

because I think if attribute is not defined, that's means that value equals 0 by default.
