Trying to generate SVG from an external graphic link but the output SVG image not rendering properly. To generate SVG using the below code,

if (osw != null)
try {
osw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
mc.dispose();
}
}
Expected Output:-
Final Output:-
So, in the final output SVG marker is getting cut from the right-hand side.
Help would be appreciated.
Thanks in advance
This is different from the previous question.
