Hello,
I have a complicated shape form which is based of arcs and lines.
It is possible to connect this arcs and lines to a closed path?
I only see drawPolygon or drawPolyline . And draw(Shape)
My problem is following:
If I transfer the lines and arcs to svg,
Inkscape and other svg editors do not see it as a shape.
So as example I can not fill this shape in Inkscape like an rectangle.
Is there a possible way to append several lines and arcs to make a closed path?
Many thanks in advance,
Geduldspiele

Re: Shape based of Lines and Arcs
Have you looked at the class java.awt.geom.Path2D ? This class allows to produce a closed shape consisting of lines and arcs.

Re: Shape based of Lines and Arcs
Paradoxoff makes a good suggestion to study Java's Path2D class. JFreeSVG maps Path2D objects from Java2D to the equivalent Path element in SVG:
It is the getSVGPathData() method in JFreeSVG that does the conversion (in this code, the geomDP() method just formats the values to a fixed number of decimal places):
Code: Select all
this.sb.append("<path ").append(getSVGPathData(path)).append("/>");
Code: Select all
/**
* Creates an SVG path string for the supplied Java2D path.
*
* @param path the path ({@code null} not permitted).
*
* @return An SVG path string.
*/
private String getSVGPathData(Path2D path) {
StringBuilder b = new StringBuilder("d=\"");
float[] coords = new float[6];
boolean first = true;
PathIterator iterator = path.getPathIterator(null);
while (!iterator.isDone()) {
int type = iterator.currentSegment(coords);
if (!first) {
b.append(" ");
}
first = false;
switch (type) {
case (PathIterator.SEG_MOVETO):
b.append("M ").append(geomDP(coords[0])).append(" ")
.append(geomDP(coords[1]));
break;
case (PathIterator.SEG_LINETO):
b.append("L ").append(geomDP(coords[0])).append(" ")
.append(geomDP(coords[1]));
break;
case (PathIterator.SEG_QUADTO):
b.append("Q ").append(geomDP(coords[0]))
.append(" ").append(geomDP(coords[1]))
.append(" ").append(geomDP(coords[2]))
.append(" ").append(geomDP(coords[3]));
break;
case (PathIterator.SEG_CUBICTO):
b.append("C ").append(geomDP(coords[0])).append(" ")
.append(geomDP(coords[1])).append(" ")
.append(geomDP(coords[2])).append(" ")
.append(geomDP(coords[3])).append(" ")
.append(geomDP(coords[4])).append(" ")
.append(geomDP(coords[5]));
break;
case (PathIterator.SEG_CLOSE):
b.append("Z ");
break;
default:
break;
}
iterator.next();
}
return b.append("\"").toString();
}
