Method defect: it is not applicable to images with a background color.

How to Use: 1. Color straw to pick up the background color;

2. Click the "color range" function in the "select" function in the menu;

3. Check Before "invert" and select the image.

 Iii. Magnetic cable sleeve Method-convenient, accurate, fast, and commonly used methods

Applicability: clear image boundaries.

Method intent: the magnetic cable cover will automatically recognize the image boundary and automatically attach it to the image boundary.

Method defect: the boundary points must be carefully placed in the fuzzy boundary.

Usage: 1. Right-click the "cable cover" tool and select the "Magnetic cable cover" tool;

2. Use the "Magnetic cable cover" tool to place the boundary points along the image boundary. A line is automatically generated between the two points and attached to the image boundary.

3. the boundary points must be carefully placed in the fuzzy boundary.

4. After the cable cover is closed, the image is completed.

  IV. (suo Yu) feathers-rough machining

Applicability: rough data extraction.

Method intent: rough plot, not accurate.

Method defect: The image boundary is not accurate.

Usage: 1. Click the "cable cover" tool;

2. Use a cable to enclose the image roughly, and the border must be close to the image boundary. This ensures the consistency of the subsequent feather range and improves the accuracy of the image;

3. Right-click the mouse and select the "Yu Hua" function;

4. Adjust the feather value. Generally, enter "20". After confirming, you will roughly select the image. The size of the feather value must be adjusted based on the margin between the border and the image in the previous step.

  5. (cable cover) Pen tool method-the most accurate and time-consuming Method

Applicability: The image boundary is complex, discontinuous, and the processing accuracy is high.

Method intent: completely place the border points one by one to help plot.

Method defect: slow. It may take about 15 minutes to pull a graph and even your fingers.

Usage:

The steps for using the pen tool are as follows:

1. Create a rough path for the cable cover

(1) use the "cable cover" tool to roughly circle the outer frame of the image;

(2) Hold down the ctrl key, hold each node (Control Point) with the mouse, and drag to change the position;

(3) Each node has two radians to adjust the radians between two nodes so that the lines are as close as possible to the image edge. This is a smooth key step;

(4) Add a node: If the node is not enough, you can press Ctrl to add the node to the path with the mouse. Delete a node: if there are too many nodes, you can press Ctrl and move the mouse over the node. When the "-" icon appears next to the mouse, click the node to delete the node.

3. Right-click "create constituency", and fill in "0" for the appearance ",,

Press Ctrl + C to copy the selection;

Create a layer or file;

In the new layer, press Ctrl + V to paste the selection area, so that it is OK!

Remove selection shortcut: Ctrl + d

Note: This tool is useless for scattered hair.

6. Easy-to-use and quick

Usage: 1. Open the photo and background image

2. Click the mobile tool to drag the photo to the background image.

3. Add a mask.

I. Erasers
Methods, features, and applicability: the eraser is used to erase unused parts and leave useful parts. This method is a simple and easy-to-use method for shape drawing, but it does not work well. It can be used for drawing with simple shape lines. However, it is mainly used to further process the effects of other methods after image extraction.
Procedure:
1. Open the image;
2. Double-click the layer and change the background layer to a normal layer.
3. Select the eraser tool. The main diameter of the paint brush is large. First, roughly erase most unused parts.
4. Select the main diameter of the paint brush and zoom in the image for detailed processing.

Ii. Magic wand tips
