Dynamic SVG image doesn't show transparent shapes in PDF report [message #662750]

Hi guys,

I have an SVG Image created using the Apache Batik framework. It's a JFreeChart panel drawn into the SVG xml file. It contains some text and shapes. And I would like to insert this image into my PDF BIRT report.

So far I have a table containing an dynamic image which is bound to a parameter of a scripted DataSet. This DataSet has an handler java class where I contribute byte array of the SVG document to the parameter. The image has also it's handler java class. In it's onPrepare() method I just set image.setMimeType("image/svg+xml").

This way the PDF report contains my SVG image. Great Surprised

But, there are 2 problems Sad

It absolutely ignores all shapes which have set the opacity (or alpha) value less than 1. When I try to save the SVG document to file.svg and open it in Gimp or Firefox, it looks fine. All transparent shapes are in.
I would like to have this image cover all the PDF page. How can I do that? Let say the SVG image document is generated with 800 x 600 pixel size. Image item is in a table. I can set size of the image item to whatever I want, but the image is either clipped or there is empty space around it. The image doesn't respect size of the image item.

Can somebody help me please? Sorry about my English.

Are you generating the PDF with the API?

What PDF Render Options are you using? Can send me an email with one of
the svg images? jasonweathersby at windstream dot net.

I use only these render options:

renderOption.setOutputFormat(RenderOption.OUTPUT_FORMAT_PDF) ;
renderOption.setOutputFileName(filePath);

where renderOption is instance of the RenderOption class and filePath is path of the PDF report file Smile

I forgot to mention that when I start generate the PDF report, it writes to the console about 20 of these messages:

Graphics2D from BufferedImage lacks BUFFERED_IMAGE hint

I can't send you the SVG file because I can't see your email address. Where can I found it?
