NullReferenceException when rendering a file

[mc0re]

This file raises a null-pointer exception in the GaussianBlur filter.

Code (WinForms, VB.NET):

Const SvgPath = "C:\...\Resources\test1.svg"
Dim mSvg = SvgDocument.Open(SvgPath)
mSvg.Width = PictureBox1.Width
mSvg.Height = PictureBox1.Height
Dim bmp = mSvg.Draw()
PictureBox1.Image = bmp

test1.zip

throws the same error on .Draw() for this fairly simple SVG file as well, generated by SVG-edit...
simple.zip

If anyone can recommend a production-ready SVG library for .NET please do!

SharpVectors?

It appears that these "'s were causing the problem in my case:
marker-start="url("#se_marker_start_svg_4")" marker-end="url("#se_marker_end_svg_4")"

I looked in your svg xml @mc0re but I wasn't able to fix anything in there that would make it render.

however, now I get this:

[mc0re]

It's not the XML that should be fixed but the code :-)

Also, SharpVectors appears not to be able to handle large resolution files, and ImageMagick doesn't produce transparent background... Is this real life?

I cannot reproduce the crash with both the example files (they are added to the test files).
The other issue with the marker arrows is already mentioned in another issue - closing this one.

[mrbean-bremen]

Ah, sorry, the first example still crashes - reopen.

[mrbean-bremen]

The first example now renders correctly except for the arrow direction handled in #215.

[mrbean-bremen]

Arrow direction is now fixed (and it was a separate problem unrelated to #215).
