本文整理了Java中java.awt.Rectangle.grow方法的一些代码示例，展示了Rectangle.grow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。Rectangle.grow方法的具体详情如下：
包路径：java.awt.Rectangle
类名称：Rectangle
方法名：grow

Rectangle.grow介绍

[英]Resizes the Rectangle both horizontally and vertically.

This method modifies the Rectangle so that it is h units larger on both the left and right side, and v units larger at both the top and bottom.

The new Rectangle has (x - h, y - v) as its top-left corner, a width of width + 2h, and a height of height + 2v.

If negative values are supplied for h and v, the size of the Rectangle decreases accordingly. The grow method does not check whether the resulting values of width and height are non-negative.
[中]水平和垂直调整Rectangle的大小。
此方法修改Rectangle，使其在左侧和右侧都大h个单位，在顶部和底部都大v个单位。
新Rectangle的左上角有（x - h、y - v），宽[$7$][$8$]2h，高[$10$][$11$]2v。
如果为h和v提供负值，Rectangle的大小相应减小。grow方法不会检查width和height的结果值是否为非负值。
