Subject [jira] [Commented] (ODFTOOLKIT-341) newImage() generates java.lang.NullPointerException when using an svg image
Date Tue, 30 Jul 2013 19:15:49 GMT


Hendrik commented on ODFTOOLKIT-341:

I'm using this toolkit from Matlab, which is the reason from the non-Java syntax:

FigurePath = File('test.svg');
FigurePath = FigurePath.toURI;
p = outputOdt.addParagraph('');
img = Image.newImage(p, FigurePath);

Like you said, this works for png files, but for svg it gives the error above unfortunately.
SVG is an excellent format for presenting graphs.

> 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
> 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?
