duplicates in SVG document

[Larry Ai <la...@yahoo.com>]

All:

    I generated a svg document (using
SVGGraphic2D.stream()) from a SVGGraphic2D object.

    I discovered that there are duplicates in the
output:

    For example:

      <polygon style="font-size:348.70587158203125;
font-family:&apos;Courier&apos;; stroke:none;"
points=" 4548 -27823 4397 -27823 4472 -28706" />
      <polygon style="fill:none;
font-size:348.70587158203125;
font-family:&apos;Courier&apos;;" points=" 4548 -27823
4397 -27823 4472 -28706" />

    There are the same polygons (same x and y
coordinates) but with some different attributes.

    Does anyone know how to get rid of those
duplicates?

    Thanks!

Larry

   These aren't really 'duplicates' one is the fill
one is the stroke.  The problem is that Java2D doesn't
have a fill/stroke operation and due to concerns about
'morphing' shape objects it is difficult to ensure that the
filled shape is the same as the stroked shape.

    Write code to detect when the stroked object
is the same as the immediately previously filled
object (perhaps by comparing the generated 'd'
attributes?) in the SVGGraphics2D or AbstractGraphics2D
class and contribute it to Batik :)
