Today I have just something small for you that might be handy in some situations. In JavaFX you could use SVG paths in CSS files to style e.g. a Region. One use case for this could be the arrow in combo box control etc.
My problem was that I needed to convert a JavaFX Path object into a SVG path and so I wrote a little method that did the trick.
Well after I wrote this method I thought it might become handy to have a tool that could convert all available JavaFX Shapes into SVG paths. The available Shapes at the moment are
To convert SVGPath into a SVG path doesn't make sense and converting Text into a SVG path is not possible at the moment because there is no way to get the Path from a Shape (which I would love to see in a future version). Means there is no support for SVGPath
and Text but for all the other Shapes I created a class named ShapeConverter that contains the following public static methods...
- shapeToSvgString(Shape param)
- shapeToSvgPath(Shape param)
- convertArc(Arc param)
- convertCircle(Circle param)
- convertCubicCurve(CubicCurve param)
- convertEllipse(Ellipse param)
- convertLine(Line param)
- convertPath(Path param)
- convertPolygon(Polygon param)
- convertPolyline(Polyline param)
- convertQuadCurve(QuadCurve param)
- convertRectangle(Rectangle param)
So you could either convert a Shape object to a String like this...
or convert a Shape object to a SVGPath object like this...
or you could directly use the specific method if you know what kind of Shape you would like to convert to a String.
I commited the ShapeConverter class to the JFXtras project so if you are interested in the code, please take a look here.
If you just would like to see the code...no problem...
I'm not sure if this might be useful for someone but I needed it and thought it might be worth sharing it with you...
It is now possible to convert also Text into SVG paths. I used a little trick to do this. Because Text is a special form of a Shape it's possible to do something like
Shape.subtract(new Text("Han Solo"), new Rectangle(0, 0))
This will return a Shape which is a Path and contains the path of the text. And a Path could be converted into a SVG path :)
That means you could use it to create SVG symbols from characters which might be useful when using a Symbol font.
so have fun and keep coding...
