hi,
Is any work being done on vector based rendering of svg in de pdf emitter?
If not, could anybody point me in the right direction of how to do it myself. I know how to get svg
into pdf using batik/itext. I had a quick look at the pdfemitter. But by the time the image data
arrives at PDFPage.drawImage(...) it is already transformed to a png image. So the svg data is not
available there. I am looking for an easy way to get the svg data available in the pdftransmitter
plugin, any hints?
greetings,
Piebe

Piebe,
Are you referring to charts?
Look at PageDeviceRender.drawImage
Also look at SvgFile.transSvgToArray

No I need to include a svg image, I do not need to render a chart (actually I assumed that the chart
would use the pdfemitter aswell to render its svg, in which case changing the emitter would solve
two things at the same time, but appearantly I was wrong there :( ) Anyway at the moment I am just
interested in an image not the chart.

Piebe,
Are you wanting a new report item that contains svg data instead of
normal image data? An SVG report item would be a good report item
extension.
If you are wanting to go this route take a look at:
rotated text example in the source code &

No I do not want to define a new report item.
I put standard image reportitem in my report which refers to a SVG image.
When I look at the report as html, this image is displayed as a svg image and therefore drawn using
vectors.
When I look at the same report as pdf, this image is displayed as a png image and therefore drawn as
a bitmap and not using vectors. This does not look very nice, does not print very well, and it is
not a very efficient way of storage for the large pictures I want to use...
Therefore I want to change the pdf emitter so that it functions the same way as the html emitter
currently works, that is let it draw a svg image using vectors and not as a bitmap.

Piebe,
Understood.
You need to look at
ImageLayout.java and SvgFile.java
ImgaeLayout.getIntrinsicDimension calls SvgFile.transSvgToArry which
converts svg to image for pdf.
