------------------------------------------

             Summary: newImage() generates java.lang.NullPointerException when using an svg
image
                 Key: ODFTOOLKIT-341
                 URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-341
             Project: ODF Toolkit
          Issue Type: Bug
          Components: simple api
    Affects Versions: 0.8
         Environment: Windows 7 Home 32 bit
JRE 7 32 bit
Eclipse Indigo SR2

odf-toolkit 0.5 
and also tried odf-toolkit SVN revision 1395734 (built with Maven on Ubuntu): simple-odf-0.8-incubating-SNAPSHOT,
odfdoom-java-0.8.9-incubating-SNAPSHOT
            Reporter: Anders Sjöström


I'm trying to create an odt file, and insert text and svg images, with limited success.
Inserting a png image is no problem, but when I change the line to insert an svg image I get
an exception.

This is the minimum program to demonstrate my problem:

import java.net.URI;
import org.odftoolkit.simple.TextDocument;

public class odfgenerator {
	public static void main(String[] args) throws Exception {
		TextDocument outputOdt;
		outputOdt = TextDocument.newTextDocument();
		outputOdt.addParagraph("Hello World.");
		//URI uri = new URI("file:///C:/Users/myuser/Desktop/simple.png");
		URI uri = new URI("file:///C:/Users/myuser/Desktop/simple.svg");
		outputOdt.newImage(uri);
		outputOdt.save("C:/Users/myuser/Desktop/HelloWorld.odt");
	}
}

If I run my program (in Eclipse) I get:

okt 08, 2012 11:30:57 EM org.odftoolkit.simple.Document newImage
SEVERE: null
java.lang.NullPointerException
	at org.odftoolkit.odfdom.incubator.doc.draw.OdfDrawImage.configureInsertedImage(OdfDrawImage.java:123)
	at org.odftoolkit.odfdom.incubator.doc.draw.OdfDrawImage.newImage(OdfDrawImage.java:147)
	at org.odftoolkit.simple.Document.newImage(Document.java:830)
	at odfgenerator.main(odfgenerator.java:12)

I delete HelloWorld.odt before every run, just to make sure. The odd thing is that despite
the exception, HelloWorld.odt is still created, with the svg file inside the Pictures directory,
and the content.xml has an draw:image tag with xlink:href="Pictures/simple.svg". The odt file
can be opened with Apache Open Office without problem, and will display the picture.

Changing the URI to point to an png file instead results in the program terminating normally
without any errors. The resulting file can also be opened with Apache Open Office without
problems.

simple.svg is a very simple svg file created with Inkskape containing two boxes, and saved
as "plain svg".

Am I doing anything wrong or is this a bug?
