What is the reason to IllegalArgumentException: negative width in kabeja

Please can some one explain the reason for an IllegalArgumentException: negative width exception being thrown when using Kabeja package?

This is the error stack that I got:

If you use kapeja-0.4, you can look up this class by org.kabeja.svg.generators.SVGInsertGenerator. detail

                AttributesImpl attr = new AttributesImpl();
            SVGUtils.addAttribute(attr, "transform", buf.toString());
            super.setCommonAttributes(attr, svgContext, insert);
            if (scale_x + scale_y != 0.0D && svgContext.containsKey(SVGContext.LAYER_STROKE_WIDTH)) {
                Double lw = (Double)svgContext.get(SVGContext.LAYER_STROKE_WIDTH);
                double width = lw * 2.0D / (scale_x + scale_y);
                SVGUtils.addAttribute(attr, "stroke-width", SVGUtils.formatNumberAttribute(width));
            }

Now you can modify by this: detail

                AttributesImpl attr = new AttributesImpl();
            SVGUtils.addAttribute(attr, "transform", buf.toString());
            super.setCommonAttributes(attr, svgContext, insert);
            double s = Math.abs(scale_x) + Math.abs(scale_y);
            if (s != 0.0D && svgContext.containsKey(SVGContext.LAYER_STROKE_WIDTH)) {
                Double lw = (Double)svgContext.get(SVGContext.LAYER_STROKE_WIDTH);
                double width = lw * 2.0D / s;
                SVGUtils.addAttribute(attr, "stroke-width", SVGUtils.formatNumberAttribute(width));
            }

If you use kapeja-0.5, you need do nothing.

Looking at the stacktrace, it seems that the error is triggered when trying to draw the stroke of a shape using a negative width. That, of course, is not correct, since there can't be a stroke of negative width. The SVG specification even mentions that a negative width is an error.

I would say that the DXF input file is wrong. Does it render fine in Autodesk? Can you find the element with the wrong stroke, and see how it's displayed?

The solution would be to file a bug report to the Kabeja project asking for a fix. Depending on how that element is displayed in Autodesk, the negative stroke width could either be:

  1. set to 0 if the stroke shouldn't be displayed
  2. set to the absolute value if the sign should just be ignored, and a width of -1mm should be the same as 1mm.
