Setting the viewBox property on the JSVGCanvas's document?
I get an error when manipulating the view box of the document on the JSVGCanvas. I do this to "resize" a document:
public void setSize(String width, String height) {
svgDocument.getDocumentElement().setAttribute(
SVGConstants.SVG_WIDTH_ATTRIBUTE, width);
svgDocument.getDocumentElement().setAttribute(
SVGConstants.SVG_HEIGHT_ATTRIBUTE, height);
svgDocument.getDocumentElement().setAttribute(
SVGConstants.SVG_VIEW_BOX_ATTRIBUTE, "0 0 " + width + " " + height);
}
To make things stranger, it only happens when I make the size smaller than it currently is. 640x480 -> 800x600 is fine. Then, going from 800x600 -> 700x600 causes the error.
Setting the width and height causes no problems, but the line that sets the view box causes this error to pop-up in the JSVGCanvas:

I've committed the fix. I'm not entirely sure that nightly builds are
working at the moment (they moved stuff on the server) I'll try and
make sure they are working again.

OK, thanks for looking into it. I will start compiling the builds I'm using with debug on. Could you let me know when you commit a fix so I'll get the right nightly build to test with?

There is a bunch of conditional code that tries to avoid a total
rebuild
of the GVT tree. Probably in the above case 800x600 -> 700x600 avoided a
total rebuild (vertical dimension was the same so scale didn't change) and
hit this bug. I'll commit a fix shortly.

It would be nice if you would compile Batik with debug turned on.
Assuming you are using our build.xml this can be done by creating a
file 'build.properties' in the same directory as build.xml and putting
the line: "debug=on" in it. Then your stack traces will have line
numbers.

There is a bunch of conditional code that tries to avoid a total
rebuild
of the GVT tree. Probably in the above case 800x600 -> 700x600 avoided a
total rebuild (vertical dimension was the same so scale didn't change) and
hit this bug. I'll commit a fix shortly.

It would be nice if you would compile Batik with debug turned on.
Assuming you are using our build.xml this can be done by creating a
file 'build.properties' in the same directory as build.xml and putting
the line: "debug=on" in it. Then your stack traces will have line
numbers.
