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:
