[BATIK-1009] rendering a GeneralPath with NaN as a point outputs a corrupt SVG path

• Type: Bug
• Status: Open
• Resolution: Unresolved
• Affects Version/s: 1.7
• Component/s: SVGGraphics2D
• Environment: Operating System: All; Platform: PC

Description

Using the SVGGraphics2D with the following code:

public void paint(Graphics2D g2d)

{ GeneralPath gp = new GeneralPath(); gp.moveTo(0,0); gp.lineTo(100,100); // OOPS!!! gp.lineTo(Double.NaN,Double.NaN); g2d.draw(gp); }

The presence of the NaN in the path will cause the SVG output to contain an invalid/corrupt path i.e.:

<path style="fill:none;" d="M0 0 L100 100 L� �"/>

Full test case added as an attachment.

I fully understand that this is not something one would normally do, but the lack of any exception/error was a surprise.
