Dear you, this is LearningYard Academy.

What Xiaobian brings to you today is<talking about PS series (2) | Basic explanation of ps constituencies and the use of tools.

PART.1.

选框工具是PS中一个非常基本的工具，在对图像中某个部分进行编辑时，就需要使用选框工具，先把这一部分框选出来。

我们可以对选区内的图像进行复制，剪切，填充或者删除，调色等操作。

下面是一些选框工具的快捷键供大家平时快捷使用：

选框工具快捷键：M

矩形和椭圆选框工具切换快捷键：Shift M
取消选区快捷键：Ctrl D

The marquee tool is a very basic tool in PS. When editing a certain part of the image, you need to use the marquee tool to select this part of the box first.

We can copy, cut, fill or delete, toning and other operations on the image in the selection.

The following are some shortcut keys for marquee tools for your daily quick use:

Marquee Tool Shortcut: M

Rectangular and elliptical marquee tool switching shortcut: Shift M

Shortcut key to cancel selection: Ctrl D

PART.2.

选框工具位于PS界面中的工具栏处，选中选框工具，鼠标右击，可以看到选框工具包含了矩形选框工具，椭圆选框工具，单行选框工具，单列选框工具。

The marquee tool is located on the toolbar in the PS interface. Select the marquee tool and right-click to see that the marquee tool includes a rectangular marquee tool, an elliptical marquee tool, a single-row marquee tool, and a single-column marquee tool.

以矩形选框工具为例，我们首先新建一个图层，选择矩形选框工具，拖出一个矩形，这个时候我们可以看见边框是不停晃动的线，我们称为蚂蚁线。

若我们不小心误触想要取消，我们只需要在最上方工具栏中【选择】然后【取消选择】即可。

Taking the rectangular marquee tool as an example, we first create a new layer, select the rectangular marquee tool, and drag out a rectangle. At this time, we can see that the border is a line that keeps shaking, which we call the ant line.

If we accidentally touch and want to cancel, we just need to [Select] and then [Deselect] in the top toolbar.

如上图所示的工具栏中，我们可以拖选两个不同的形状选区进行合并，删除等。

As shown in the toolbar above, we can drag and select two different shape selections to merge, delete, etc.

PART.3.

在一些特殊情况下，需要我们处理的图形不是规整的图形，这样我们接下来介绍更加复杂的选择工具。

In some special cases, the graphics we need to deal with are not regular graphics, so we will introduce more complex selection tools next.

在工具栏中，可以看见一个绳子一样的工具，鼠标右键单击，即可看见套索工具，多边形套索工具和磁性套索工具。

1、套索工具，可以由我们手动框选我们需要的区域。大多数情况下用的较少。

2、多边形套索工具，顾名思义，我们可以使用这个工具框选出各种不规则形状的多边形。

3、磁性套索工具：能通过图像像素的颜色差异自动识别边界，特别适合快速选择与背景对比强烈且边缘复杂的图像。

In the toolbar, you can see a rope-like tool, right-click to see the lasso tool, the polygonal lasso tool and the magnetic lasso tool.

1. Lasso tool, we can manually select the area we need. Less used in most cases.

2. Polygonal lasso tool, as the name suggests, we can use this tool box to select various irregularly shaped polygons.

3. Magnetic lasso tool: It can automatically identify the border through the color difference of the image pixels, especially suitable for quickly selecting images with strong contrast with the background and complex edges.
