问题描述
我希望通过将对象(带有绘制功能)添加到屏幕上沿形状周边的适当位置来为Shape(AWT)创建动态轮廓.我希望每个对象之间的距离大致相等. (对这种影响的替代方法也可以.)
I wish to create a dynamic outline to a Shape (AWT) by adding objects (with draw functions) to appropriate positions on screen along the shape's perimeter. I want a roughly even distance between each object. (An alternative approach to the same affect will be fine.)
如何获取这些对象的位置?我知道形状具有路径迭代器，但是我不知道如何使用它.
How might I acquire the locations for these objects? I know shapes have a path iterator, but I have no idea how to use it.
推荐答案
您可能会看到诸如 形状图编辑器 .
You might look at a library such as the one described in A Shape Diagram Editor.
如果您想尝试， GraphPanel 是一个简单的对象绘制程序具有通过边缘连接的可移动，可调整大小的彩色节点.如果节点小一点，它们将是Shape上的可移动点，可以按此处所示进行迭代用于Polygon.
If you want to experiment, GraphPanel is a simple object drawing program that features moveable, resizable, colored nodes connected by edges. If the nodes were a little smaller, they'd be moveable points on a Shape that can be iterated as shown here for Polygon.
附录:我希望每个对象之间的距离大致均匀.
class Node公开了许多对List<Node>进行操作的静态方法，例如selected.现有的实现例如用于翻译或调整多个选择作为一个单元的大小. Align和Distribute的功能可以类似地实现.我将以LayoutManger作为后者的示例.
The class Node exposes a number of static methods that operate on a List<Node> such as selected. Existing implementations serve, for example, to translate or resize multiple selections as a unit. Functions for Align and Distribute could be implemented similarly. I'd look at LayoutManger as an example for the latter.
