Check out the [SVG framework in C# and an SVG-GDI+ bridge][1] project.

From the above web page...

&gt; The SvgGdi bridge is a set of classes
&gt; that use SvgNet to translate between
&gt; SVG and GDI+. What this means is that
&gt; any code that uses GDI+ to draw
&gt; graphics can easily output SVG as
&gt; well, simply by plugging in the
&gt; SvgGraphics object. This object is
&gt; exactly the same as a regular .NET
&gt; Graphics object, but creates an SVG
&gt; tree. Even things like hatched fills
&gt; and line anchors are implemented.

We have made a public fork of the C# .NET SVG library on Github.

It is much improved over the one you find on Codeplex, please have a look and fork it as you like:

https://github.com/svg-net/SVG

**Edit:**
Just to let you know, as of January 2021: 

While others seem dead for years, this is still active. But we could definitely use some help from other developers.


I used this one [http://svg.codeplex.com/][1] and I am quite satisfied with it. Still has some bugs so you should have a look at the patches in [http://svg.codeplex.com/SourceControl/PatchList.aspx][2].

When I discover mistakes I can solve I post them directly there. But it takes some time to be evaluated by the guys there. It&#39;s a better idea to have a look at the patches and apply them yourself.

The library is reasonably sufficient for most usual needs. for really fancy stuff, it needs to be improved thought...

As SVG is basically a XML document - you can implement &quot;drawing&quot; yourself. Check the specs at [W3C SVG spec][1]. I did it once to generate SVG signature images, all it took was a couple of hours and a firefox to test the generated image.

Of course this applies if you are generating image from user input or if you do not mind spending some time doing conversion from another vector image format.

P.S. you can create your own wrapper to mimic System.Drawing.Graphics, e.g. DrawLine() to append &lt;Line/&gt; to the internal buffer and so on.

To rephrase the question: should I avoid sharing instances of classes which implement `java.sql.Connection` between different threads?

Is java.sql.Connection thread safe?

Is there a way to comment various lines at the same time in Xcode IDE? Selecting which lines to comment, then clicking somewhere et voil&#225;.. the /* ... */ characters wrapping the code.

I&#39;d like to generate an SVG file using C#. I already have code to draw them in PNG and EMF formats (using framework&#39;s standard class [System.Drawing.Imaging.Metafile][1] and [ZedGraph][2]). What could you recommend to do to adapt that code to SVG? Preferably I&#39;d like to find some library (free or not) that would mimic [System.Drawing.Graphics][3] interface.

In C#/.NET `TimeSpan` has `TotalDays`, `TotalMinutes`, etc. but I can&#39;t figure out a formula for total months difference. Variable days per month and leap years keep throwing me off. How can I get **TotalMonths**?

**Edit** Sorry for not being more clear: I know I can&#39;t actually get this from `TimeSpan` but I thought using `TotalDays` and `TotalMinutes` would be a good example to express what I was looking for ... except I&#39;m trying to get Total Months.

Example: Dec 25, 2009 - Oct 6, 2009 = 2 TotalMonths. Oct 6th to Nov 5th equals 0 months. On Nov 6th, 1 month. On Dec 6th, 2 months

Reading through the existing unit testing related threads here on Stack Overflow, I couldn&#39;t find one with a clear answer about how to unit test file I/O operations. I have only recently started looking into unit testing, having been previously aware of the advantages but having difficulty getting used to writing tests first. I have set up my project to use NUnit and Rhino Mocks and although I understand the concept behind them, I&#39;m having a little trouble understanding how to use Mock Objects.

Specifically I have two questions that I would like answered. First, what is the proper way to unit test file I/O operations? Second, in my attempts to learn about unit testing, I have come across dependency injection. After getting Ninject set up and working, I was wondering whether I should use DI within my unit tests, or just instantiate objects directly.

If I have two lists of type string (or any other type), what is a quick way of joining the two lists?

The order should stay the same. Duplicates should be removed (though every item in both links are unique). I didn&#39;t find much on this when googling and didn&#39;t want to implement any .NET interfaces for speed of delivery.


Joining two lists together

Is there a way to take a List&lt;int&gt; and convert it into a comma separated string?  

I know I can just loop and build it, but somehow I think some of you guys a more cool way of doing it?

I really want to learn these types of &#39;tricks&#39;, so please explain or link to the docs on the method you use.

Converting a List&lt;int&gt; to a comma separated string

To cut a long story short: I find the [Java antipatterns][1] an indispensable resource. For beginners as much as for professionals. I have yet to find something like this for C#. So I&#39;ll open up this question as community wiki and invite everyone to share their knowledge on this. As I am new to C#, I am strongly interested in this, but cannot start with some antipatterns :/

Here are the answers which I find specifically true for C# and not other languages.

*I just copy/pasted these! Consider throwing a look on the comments on these as well.*

----------------------------------------------------------------------------------------

# [Throwing `NullReferenceException`][5]

Throwing the wrong exception:

    if (FooLicenceKeyHolder == null)
        throw new NullReferenceException();

----------------------------------------------------------------------------------------

# [Properties vs. public Variables][2]
Public variables in classes (use a property instead).

**Unless** the class is a simple Data Transfer Object.

----------------------------------------------------------------------------------------

# [Not understanding that bool is a real type, not just a convention][3]

    if (myBooleanVariable == true)
    {
        ...
    }

or, even better

    if (myBooleanVariable != false)
    {
        ...
    }

Constructs like these are often used by `C` and `C++` developers where the idea of a boolean value was just a convention (0 == false, anything else is true); this is not necessary (or desirable) in C# or other languages that have real booleans.

----------------------------------------------------------------------------------------

# [Using `using()`][4]

Not making use of `using` where appropriate:

    object variable;
    variable.close(); //Old code, use IDisposable if available.
    variable.Dispose(); //Same as close.  Avoid if possible use the using() { } pattern.
    variable = null; //1. in release optimised away.  2. C# is GC so this doesn&#39;t do what was intended anyway.

The documentation for getBoundingBox() in dojo says:

&gt; Returns a bounding box of a shape. A
&gt; text shape is a point-based object, so
&gt; it doesn&#39;t define a bounding box.

I don&#39;t get it. Any sane implementation of vector graphics for the web includes bounding box for text objects (raphaelJS and jQuery SVG that is)! Here, what does &quot;a point based object&quot; mean?

I found no reference for a bounding box for Group object, but when using the latest Dojo version, `getBoundingbox` returns `null` for Groups as well

I can easily do bounding box for rectangle myself, but the only really problematic shapes I need bounding box for are the Group and the Text.

I ended hotpatching dojo like:

    dojox.gfx.Text.prototype.getBoundingBox = function() { return this.rawNode.getBBox();});
    dojox.gfx.Group.prototype.getBoundingBox = function() { return this.rawNode.getBBox();});

Which will of course work only for the SVG output front end.

But I wonder, am I missing something? Is there a better way to do that?

dojox.gfx bounding box for Text and Group nodes

I&#39;m working on some ECMAScript/JavaScript for an SVG file and need to get the `width` and `height` of a `text` element so I can resize a rectangle that surrounds it. In HTML I would be able to use the `offsetWidth` and `offsetHeight` attributes on the element but it appears that those properties are unavailable.

Here&#39;s a fragment that I need to work with. I need to change the width of the rectangle whenever I change the text but I don&#39;t know how to get the actual `width` (in pixels) of the `text` element.

    &lt;rect x=&quot;100&quot; y=&quot;100&quot; width=&quot;100&quot; height=&quot;100&quot; /&gt;
    &lt;text&gt;Some Text&lt;/text&gt;

Any ideas?

How to convert a PNG image to a SVG?

There are different ways to show graphics in a page next to text.
I need to include a graphic/icon that indicates a new tab will be opened.

I know it&#39;s possible to do using at least these different methods:
- Unicode character from default fonts
- Unicode character from CSS loaded fonts
- Inline SVG
- Inline PNG

Please suggest a method to do this, and explain why or why not it&#39;s robust on different browsers and operating systems.

I&#39;m a newbie to both R and LaTeX and have just recently found how to plot a standard time series graph using R and save it as a png image. What I&#39;m worried about is that saving it as an image and then embedding it into LaTeX is going to scale it and make it look ugly.

Is there a way to make R&#39;s `plot()` function output a vector graphic and embed that into LaTeX? I&#39;m a total beginner in both so please be gentle :) Code snippets are highly appreciated!

To get the center, I have tried, for each vertex, to add to the total, divide by the number of vertices.

I&#39;ve also tried to find the topmost, bottommost -&gt; get midpoint... find leftmost, rightmost, find the midpoint.

Both of these did not return the perfect center because I&#39;m relying on the center to scale a polygon.

I want to scale my polygons, so I may put a border around them.

What is the best way to find the centroid of a polygon given that the polygon may be concave, convex and have many many sides of various lengths?

I&#39;m wondering how vector drawing in Android with the `Shape` class may resemble another vector drawing standard.

Since `Shape` is a `Drawable`, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG.

My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting an SVG drawing description into Android Shapes?

SVG to Android Shape

Should I use `&lt;img&gt;`, `&lt;object&gt;`, or `&lt;embed&gt;` for loading SVG files into a page in a way similar to loading a `jpg`, `gif` or `png`?

What is the code for each to ensure it works as well as possible? _(I&#39;m seeing references to including the mimetype or pointing to fallback SVG renderers in my research and not seeing a good state of the art reference)._

Assume I am checking for SVG support with [Modernizr][1] and falling back (probably doing a replacement with a plain `&lt;img&gt;` tag)for non SVG-capable browsers.
