用PhotoshopCS 5直接画一个矩形边框
用Photoshop画矩形的时候，有时需要就画一个单一的边框，内部不需填充颜色，而且边框可以调节宽度和颜色。这时就可以用选择工具拉个矩形框，然后点主菜单，选编辑->描边，再在跳出的窗口选择相关的参数，最后点确定就可以了。
下面我就以PhotoshopCS5来举例:
一、首先新建一个文档或打开一张图片， 然后在新建一个图层，点击![](https://wkrtcs.bdimg.com/rtcs/image?w=114&md5sum=ea99973aa111af234d0a234890bfe711&sign=429a4201f0&rtcs_flag=1&rtcs_ver=3.10&l=webapp&bucketNum=43&ipr={"t":"img","w":"114","h":"83","dataType":"png","c":"word/media/image1.png","imgOriW":165,"imgOriH":120})
矩形工具。选择左上角工具栏的路径按钮。
注: 如果是新建一个文档，在新建对话框的颜色模式选项卡中选RGB颜色，见下图。

二、拉出矩形框，并按鼠标右键，点选“建立选区”。

![](https://wkrtcs.bdimg.com/rtcs/image?w=227&md5sum=ea99973aa111af234d0a234890bfe711&sign=429a4201f0&rtcs_flag=1&rtcs_ver=3.10&l=webapp&bucketNum=43&ipr={"t":"img","w":"227","h":"186","dataType":"png","c":"word/media/image6.png","imgOriW":299,"imgOriH":245})
三、点击“编辑”∣“描边”。

四、设置线宽和颜色。

注:PS改变不了前景色处理:①点击菜单“图像”=>模式=>RGB。②将上图差值改为正常。

五、按Ctrl+D 取消选择，去掉路径虚线。

六、调整大小
按CTRL+T进行大小调整，调整到合适大小之后，在矩形路径内点右键选择建立选区就OK了。
七、调整位置
如果位置不合适可以用方向键移动。
八、看尺寸
按F8出来对话框的右下角的尺寸就是，注意要把单位设置为厘米。
