I have draw on Text 'L' in inkscape. i got coordinate in svg file like
d = "M 211.06641,183.00775 L 218.16797,183.00775 L 218.16797,229.51947 L 243.72656,229.51947 L 243.72656,235.49603 L 211.06641,235.49603 L 211.06641,183.00775"
After Rotate 90 degree clock wise i got coordinate like

transform="matrix(0,1,-1,0,436.64837,-18.144595)">
<path
style="marker:none"
d="M 211.06641,183.00775 L 218.16797,183.00775 L 218.16797,229.51947 L 243.72656,229.51947 L 243.72656,235.49603 L 211.06641,235.49603 L 211.06641,183.00775"



Here You can see coordinate are same but after rotation of text transformation apply on old one coordinate. But here i want to get new coordinate after transformation .

How is it possible ?

This subject is way beyond my understanding, but I think I've read about an extension, or something, that someone wrote, to do just what you're describing. Let me do some searching and try to find it. I'll post back once I either find it or can't find it

Edit
Ok, actually I found it fairly quickly This informative topic should prove helpful. I'm not sure if it's exactly what you want, but it might help: viewtopic.php?f=5&t=8826

Edit #2
There might also be an extension, have a look at the repository: http://wiki.inkscape.org/wiki/index.php ... Repository
