This is a follow up to my related question posted previously.
My .NET application can now successfully convert a VML file to SVG, using the XSLT provided by VectorConverter and the .NET XslTransform class.
For all browsers except IE, the Inkscape command line utility works perfectly well. I get a nice PNG image of my entire SVG drawing. However with IE, the output PNG is only of a very small portion of the input SVG. Has anyone else had this problem?
It turns out that code output by the VML --> SVG transformation was missing out the dimensions in the XML tag, as in:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg"
width="xx" height="yy">
</svg>
I got around it by reading the file back, adding the width and height attributes and then re-writing the file. It's not a great solution but it works for the time being, I've still not managed to find the underlying issue - if I do I will post it back here.
