Hi,

i need some SVGNodes in my little application, like the mindfusion iconnode sample. Is there anywhere a code-snippet how i could realize this task? That meens i have to write a new "SVG_Node" class with a custom svg-image and custom properties for each SVGNode.

I have tried the following code:



<sup>'
' Copyright (c) 2003-2009, MindFusion LLC - Bulgaria.
'
Imports System.Drawing.Imaging
' ...
Imports MindFusion.Diagramming
Imports MindFusion.Drawing
Imports MindFusion.Svg


Public Class IconNode_Node
Inherits SvgNode

Shared Sub New()

End Sub

Public Sub New(ByVal diagram As Diagram)
' ...
MyBase.New(diagram)
' ...
Dim newContent As New SvgContent()
newContent.Parse(Application.StartupPath & "\images\Node.svg")
' ...
Content = newContent
Transparent = True
HandlesStyle = MindFusion.Diagramming.HandlesStyle.EasyMove
' ...
End Sub

End Class</sup>


This code works, but if i select a svgnode in my diagram, a white rectangle appears over the selected svgnode, but why...???

Hi Stoyo,

i have found my mistake, i also attach a IconNode to the SVGNode which lies over the SVGNode.

What do you think about the above posted code?Im not shure, but should i add the draw and drawshadow Sub to the class?

1. It depends on whether you need to draw anything else apart from the SVG?

2. We have recently found there's some kind of "pattern" objects in SVG, which we haven't implemented in our rendering library. Are you using this feature in your SVG file? Could you email it to support@mindfusion.eu in any case?

What version of the control are you using? The parsing speed was improved a lot in version 5.3.1. We'll check what's wrong with the curve elements now.

Is the file you sent us the one created with Adobe CS? It gets loaded instantly in my test project. If not, could you send us the Adobe file too?

It took less than a second to load on my system, You might try removing the following line form the svg:

<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">

Otherwise the MSXML parser downloads the dtd file to validate the xml schema, so it might take more time depending on the Internet connection speed.

We've fixed the problem with the curves too. We are making some other changes right now, but will try to upload a stable build with the fix in a few days.
