I'm using this library as a svg render engine. I'm trying to load some svg files with texts and I see that the "letter-spacing" attribute has no effect. Are there any solutions?

I found also another problem: if I load a svg text with border I see the pen definition, and it's ok; if the text is over a path, the pen definition disappear and it's impossible to see the border in the xaml.

Thank you

I have not seen any problem with the letter-spacing as you can see in the test samples.
For this and the border issue, if you can create a simple test svg file for me, I will investigate
the issue.

Hi Paul,

at the end of this message you can find the body of a svg file whit the problems which I exaplain.


I decided to modify directly your code and I saw that element.GetAttribute("letter-spacing"); return an empty value, so I've wrote a new function. After that I add this progress += LetterSpacing / _pathLength; to the progress value to shift the charters.


For the second problem when you write a text on path you use this method dc.DrawText(formText, _formattedOrigins[i]); that paint glyphs, but glyphs doesn't support stroke property so I changed it with  

Geometry textGeometry = formText.BuildGeometry(new Point(0,0));               

dc.DrawGeometry(Foreground, textPen, ExtractTextPathGeometry(textGeometry));

so texts always are drawed by paths, and paths support stroke.


Another problem that I found the last week was the bounds value of the objects: they go from 0 to a positive value, and if I've a shape with negative coordinates, it will crop. Today I'll try to solve this.

Hello Luca,

Thanks for the information and the test file (wished you used the code feature of the Codeplex editor to display it formatted).

I will look into the problem, just give me a little more time.
I have started a new job, working with Java in the first project and I needed to update my Java knowledge, all my current books are even too old :(

Best regards,
