问题描述
JavaFX在和高级节点。
JavaFX provides both low-level path painting methods on a GraphicsContext and a high-level Path node.
我想在类中存储形状并在 GraphicsContext 中绘制它们。 Path 类对我来说似乎很方便。我知道，它应该用作场景图中的一个节点，但它包含我需要的所有绘图元素。
I want to store shapes in classes and draw them in a GraphicsContext. The Path class seems convenient for me. I know, it is meant to be used as a node in the scene graph, but it contains all drawing elements I need.
我正在寻找像$ b这样的方法$ b GraphicsContext.fillPath（路径）
但没有。
I am looking for a method likeGraphicsContext.fillPath(Path)but there is none.
我是否需要迭代手动覆盖 Path 元素并将它们转换为低级 GraphicsContext 方法，还是我错过了什么？
Do I have to iterate over the Path elements by hand and translate them into low-level GraphicsContext methods, or did I miss something?
推荐答案
是的。您需要编写一个翻译器来获取从并调用相应的图形上下文方法（参见），例如 beginPath（）， moveTo（）， lineTo（）， closePath（）， fill ， stroke（）等。
Yes. You will need to write a translator to take data extracted from a Path and invoke appropriate graphics context methods (see the Path Rendering methods), for example beginPath(), moveTo(), lineTo(), closePath(), fill, stroke(), etc.
您可以使用。将SVGPath从场景图节点数据转换为GraphicsContext方法很容易 - 您只需执行。
Rather than using a Path, you could perhaps use an SVGPath. It is easy to translate an SVGPath from a Scene graph node data to a GraphicsContext method - you can just do gc.appendSVGPath(svgPath.getContent()).
