本文整理了Java中ij.gui.Line类的一些代码示例，展示了Line类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Line类的具体详情如下：
包路径：ij.gui.Line
类名称：Line

Line介绍

[英]This class represents a straight line selection.
[中]此类表示直线选择。

代码示例

var line1 = new Line(0, 0, 0, 100);
var line2 = new Line(0, 100, 100, 100);
var line3 = new Line(100, 100, 100, 0);
var line4 = new Line(100, 0, 0, 0);
