Exception with Batik slideshow
Hi,
I am trying to use Batik slideshow software to display a fullscreen SVG
file, but when I execute the command I obtain a black full screen and I get
an exception. Following is what I obtain:
I:\>java -jar batik-1.7\batik-slideshow.jar Result\display.svg
Reading: file:/I://Result/display.svg
Building: file:/I://Result/display.svg
Rendering: file:/I://Result/display.svg
Painting: file:/I://Result/display.svg
Exception in thread "TransitionThread" java.lang.NullPointerException at
org.apache.batik.apps.slideshow.Main$TransitionThread.run(Main.java:265)
I tried several SVG contents and even with the most simple one I obtain this
error. Following is a sample SVG content I tried to display:
<?xml version="1.0" encoding="UTF-8"?><svg xmlns="http://www.w3.org/2000/svg
">
<text fill="darkslateblue" text-anchor="middle" font-weight="bold"
font-size="26" y="300" x="512">Results</text>
</svg>
Is there anything wrong with my usage of this software?
Where can I find more documentation on this tool (I didn't find anything
about slideshow on the batik pages)?
Here is some information on my configuration:
OS: Windows XP Pro SP2
Java: 1.6.0_06
Batik: 1.7
Regards,
Gonzague Reydet.

Great! Glad to know it helped. :-) I'm not familiar with the tool so
we better wait for some feed back from a Batik development team
member...

Humm. This seems to be tricky. Are presentations meant to change that
often? I'm confident that you are able to implement this feature into
the tool but I don't think it will support this out of the box and/or
without any modification.

It's a limitation of the slideshow app.

The slideshow only supports static SVG. I would suggest using two
JSVGCanvas's if you want to show animation.

It's possible but you would have to write the code ;)

Re: Exception with Batik slideshow

In fact slideshow works when I add the width and height parameters in the
top level svg element. Are those parameters required in the SVG
recommendation or is it a bug/limitation of slideshow?
Another issue is that I can't run animated SVG within batik slideshow
whereas the animation works within squiggle. Does slideshow support animated
SVG or is it another limitation of this tool?
Finally is it possible to make slideshow reload the SVG file automatically
each time this one is modified?
Thank you for your reply,
Gonzague Reydet.

I'd say there's nothing wrong with it. Few suggestions which may help
finding out the root cause (to help tracking down the issue):
* Try setting "height" and "width" properties to "100%" on the root
"svg" element: although they are implicit, there may be some issue
with the default canvas used by the tool;
* Replace "darkslateblue" with an hexadecimal-based color: may Batik
miss some more excentric colors?
Please make these (and potentially more) attempts to try reducing
(therefore isolating) the problem so a Batik developer can take a more
informed look at this potential issue. ;-)

Apparently the only documentation is the one shipped with the tool
itself (i.e., the argument list displayed when the tool is invoked
without any parameter). There seem to be 5 applications (rasterizer,
slideshow, svgbrowser, svgpp, ttf2svg) but only 4 have their own
documentation [1]. Could you try to marsh up a documentation section
and/or separate documentation page to be added there? ;-)
