Dynamic image generation
Hi all,
Are there any plans at all for providing support for SVG or any other
technology enabling the dynamic generation of 2d images?
Thanks,
Emmanuel Jay

Well, that example is so simple. I did not generate the svg file, but
you can do that with Graphics2D, direct xml, etc. It just transcodes
an svg (it was only a test).
Get the code from http://people.apache.org/~baranda/baranda_webcomponents.tar.gz
It is an eclipse project with everything packed inside, including a
build.xml file to compile, create the jar and the example webapp.
Enjoy! :-)

Thanks for that Bruno
So in the raster example you generate the primitive shapes on the fly (using
the normal Graphics2D I suppose), then create an SVG document using the
Batik Generator and then use the transcoder to save as JPEG or PNG and then
stream that out... Is that correct? (or you have the SVG and use the
transcoder on it directly)
I would be very interrested in looking at your code :)
Thanks,
Emmanuel

Ok, I've uploaded a webapp with the graphicSVG example in
http://people.apache.org/~baranda/baranda.war
Feel free to try it, just drop it in (if possible) clean server and
that's all. If someone is interested in the source just ask. Now,
there are two examples: one that just put the svg render in the page
inside <object> tags and another one that rasters the images
on-the-fly using the batik libraries.
Now the component is very basic, and it only allows it to raster the
svg or not and choose between png/jpeg format. No compression at the
moment, because I only did the component for test purposes...
Every example has the source for the jsp page, in the myfaces examples way...
Criticism and opinions accepted, of course!

Bruno

Yes more SVG browser support is definitely needed...
I am interrested in having something like the SVG Generator in Batik that
would provide a very easy way to generate 2d rasters on the fly. In that
respect I might even be able to use the SVG generator straight out of the
box I guess (I admit I have never used it, I am currently reviewing what is
the best way to achieve that).
In terms of a JSF component I was more refering to a render kit that would
render the SVG generated by the SVG generator.
Could you give me a bit more info on what the graphicSvg component does, and
what it offers. Is is build on top of batik? Can I just feed it with an SVG
and it will render it in the browser... will it compress the image?
Thanks,
Emmanuel

And it would not only be needed a new render-kit, but also a new set
of svg components! That are major words...

Creating a component that renders svg files would be pretty
straight-forward, as what you would do is to create a component which
accepts the svg files and embedes it in the page using the <object>
tags... Using the batik library, you could raster the svg files
on-the-fly to generate PNG or JPEGs.
If what you want is an SVG render-kit, this is more difficult and
would imply more code (that was a good idea for the Google summer of
code!).
I've developed the graphicSvg component (the first case) some time
ago, but didn't have time to finish it, although it works... more or
less. However it is capable of showing the SVGs and rastering them. I
haven't included it to the sandbox because it has a dependency in the
batik library. If someone is interested, feel free to contact me...
For the whole render-kit, maybe that would be another project...
Regards,
Bruno
PS we still need more svg browser support...
