Eraser tool

About using the eraser tool in ps 1. The "eraser tool" in the ps tool bar (a), (b)

The extended tool that pops up when you open the Toolbar Eraser tool has three tools: the Eraser Tool, the Background Eraser Tool, and the Magic Eraser Tool.

1. Select "Eraser Tool" in the toolbar or press "e" on the keyboard (because the shortcut key of the eraser is e on the keyboard), its function is to erase some unwanted parts. If you want to erase the background layer, the erased part will display the background color you set (for example, if the background color is red, its erased part is also red). If it is set to a normal layer, you can double-click After the layer, a new layer dialog box will appear. Click it to become a normal layer, and the erased part will become a transparent area display (ie, mosaic-like).

2, look at the "Eraser Tool" property bar:

(1) You can set the size of the "Eraser Tool" and its degree of softness and hardness;

(2) Mode: There are three modes: "brush", "pencil" and "block". If you choose "brush", its edges appear soft and you can change the softness of the "brush". For example, if you select "pencil", the erased edge will become sharp; if you select "block", an eraser will become a The blocks turn round;

(3) When using "Opacity" after "Brush" in "Eraser Tool" "Mode", if you add another picture to the original picture, use "Eraser Tool" and set "Opacity" to 100 When erasing the image, you can erase the rear image by 100%. If the "opacity" is set to 50%, you cannot erase all the images when it is erased and the effect is transparent.

Second, the background color eraser tool in the ps toolbar:

1. Use the "Background Color Eraser Tool". The erased object is the color touched by the center point of the mouse. If you place the mouse over a certain point in the picture, the position of the wiper head will become the color touched by the center point of the mouse. , If you touch the center point of the mouse to another color on the picture, the "background color" will change accordingly;

2. Property bar of "Background Color Eraser Tool":

(1) There are three options for sampling: Continuous, One time and Background color version. If you select Continuous, the color touched by the center point of the mouse will be removed when the mouse is held down. .

(2) If you select "Once", only the first contact color will be erased when you hold down the mouse. If you pass different colors, the color will not be erased unless you click again. The other colors will be erased after a while.

(3) If you select "Background Color Version", only the background color and the set color will be erased. If the background color is set to yellow and the foreground color is set to green, for example, the background on the picture is blue, the picture is The yellow color is the same as the background color setting. Then we place the mouse on the blue color, but the blue color is not erased. Only the mouse passes through the yellow area on the map and the background color is the same.

3. Limitations of the "Background Eraser Tool" in the column: There are also three options for the limit: "Disconnect", "Adjacent" and "Find Edge";

(1) "Discontinuity": Use the brush tool to draw a closed line on the screen, then select the eraser tool, select "discontinuity" and define it as a continuous within the sample. For example, we zoomed in on the eraser hoe to Can cover the color inside a closed line drawn. After clicking the eraser tool, we found that the color covered around the center point of the mouse was cut off;

(2) For example, if we select adjacent again, we can find that the color of the mouse park has been erased by clicking the mouse, but the color outside the lines has not been erased. This is the method of disconnection and adjacent use;

(3) If you use "find the edge": Use the mouse to click on the edge where the color touches. We find that only the color at the edge is erased and the other colors are not erased.

(4) "Tolerance" and "Protect foreground color": If the "Protect foreground color" accessory box is not checked, if the foreground color is set to yellow, a color block is also filled with the foreground color on the picture, and then the front protection is cancelled. Select the checkbox in front of the scenery, then select the background eraser tool to erase the colors on the image. At this time, we find that all the places where the mouse passes are erased. If the protection of the foreground is checked, we find that all the places where the mouse passes All are erased and the image set with the foreground color is not erased. This is the role of "protecting the foreground color".

(5) "Tolerance": The "Tolerance" value mainly sets the erasing range of the mouse. The higher the "Tolerance", the larger the erasure range;

Third, the magic eraser tool in the ps toolbar:

1. The "Magic Eraser Tool" is similar to the "Magic Wand Tool" in the toolbar. The "Magic Wand Tool" is used to select color. You can change its "tolerance" to select different ranges of color blocks, such as There are two colors of blue and yellow on the picture. We can see that the "tolerance" value is 32. Click the blue area on the picture with the mouse to erase it, and click on the yellow color to erase it. Now, this is the use of the magic eraser tool;

2. "Anti-aliasing" and "adjacent": For example: if you do not check "adjacent", just click the yellow color, then the entire yellow color will be erased;

3. For "all layers": If there are multiple layers on the image, we can check it to use the "Eraser Tool" on multiple layers. If unchecked, only modify the current layer;

4. It can also change its transparency.
