SVG

Question

Does anybody have an idea how to display SVG graphics with windows forms. We have a requirement to display and print SVG and to have an editable layer on top of the SVG graphics.

is there a XAML component that is already working with the .net 2.0 framework. We can't ship a comunity technology preview.

thanks for any help

Answer 1

There is no XAML component apart from the CTP stuff.

SVG runs in a browser, so you could embed IE in your app and install SVG to the local system.  I've not heard of any non browser support for SVG, although it would not surprise me.

 I should mention that SVG and WPF, although both XML based, are totally different beasts.  WPF does not support SVG.

Hi,

Sure XAML and SVG aren't quite the same, but you can convert a subset from SVG to XAML and if there would be a XAML component not running under the CTP - I would probably be allright.

Is there a way to convert SVG to an other common vector format - well, EMF would be allright... but there is no way to convert SVG to EMF, is there?

 

 

Answer 3

Yes, I'm sure you could write an XSLT that would convert between the two.

I take it your SVG image is going to be static then, no animations ? There's no automatic way to do that conversion that I know of, no, and when I looked at the metafile support in .NET ( admittedly it was .NET 2002 ), it was very, very broken. 

Assuming you're just displaying a vector image that happens to be done in SVG, perhaps you could write code to parse the SVG and just render it yourself ? If it's just static lines and shapes, that shouldn't be too hard, probably easier that writing code to convert SVG to EMF.  It's a bit of work though, compared to a canned solution, if one existed.

The other issue with WPF is that it only works on XP SP2 and above.

Hi,

What do you mean "it was very, very broken" ? Can you point out what worked and what didn't? You statement sounds a little unclear.

The other thing is, that as soon as you can render to a graphics object you get an emf for free. I don't understand your point why rendering should be cheaper than converting to emf. Could you point that our for me, too?

Anyway, I made my mind up and wrapped the SVG rendering Engine from SvgVectors (https://sourceforge.net/projects/svgdomcsharp/) to write me an EMF. So far I haven't noticed any side effects. Anyway, it's a hack, but working properly with our samples.
