I am try to convert the svg with css into image, however, I haven't
got a way to convert the expected, the css style is lost in the
converted image .The test code is as following, the rect should be
with fill color, however, the converted image doesn't have the fill
color
String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
[...]
Element defs = doc.createElement(defs);
You need to use 'createElementNS(svgNS, element name)'
instead of just createElement(element name). If you just use
createElement you will not get SVG elements, so they won't be
rendered (the problem was more than just CSS).
This applies to every place you create an element.

Dimensions are too large exception
I am trying to convert a wmf image into a jpg image, my code looks like
/***code ***/
ImageInfo info = imageManager.getImageInfo(uri, sessionContext);
if(pictName.equals(image22.wmf)){
info.getSize();
String S = PAWAN;
}
//Load image and request Graphics2D image
g2dImage = (ImageBuffered)imageManager.
getImage(info, ImageFlavor.BUFFERED_IMAGE,
sessionContext);
g2dImage.getBufferedImage().getHeight();
g2dImage.getRenderedImage().getHeight();
g2dImage.getSize().setSizeInPixels
(info.getSize().getWidthPx(), info.getSize().getHeightPx());
OutputStream os =
unit.getStreamProvider().createFile(pictName+.jpg);
ImageIO.write(g2dImage.getRenderedImage(), jpg, os);
/***end code***/
while this works for half of the sample size that I have.
For the other half, I get a Dimensions are too
large exception exception, the stack trace is
/** stack trace /

I tried looking at AbstractWMFPainter's getImage method where I guess this
size is calculated. That code is way too complicated for me to understand
:(.
Is there a way to get this working or to downsize for large images?.
Thanks,

Re: Minimum acceptable/desired Java version and related thoughts
Hi everyone, In the scope of bug 46434 [1], I believe it was highly desired to have user feedback about this. It's great to see user expressing their feedback, thanks! :-) FYI, Java 5 is already end of life as well, http://java.sun.com/j2se/1.5/ Yeah, but Java for Business releases will be supported for up to eight years from initial release date [1], which means that 1.5 should still be around for a few years more. ;-) Cheers Tonny Kohar Cheers, Helder [1] http://www.oracle.com/us/technologies/java/java-for-business-071123.html - To unsubscribe, e-mail: batik-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: batik-users-h...@xmlgraphics.apache.org
