1, open the picture in PS;
2. Click and hold "Quick Selection Tool" in the left toolbar, and select "Wand Tool" from the pop-up options;
3. Click on the text to be dug with the magic wand tool, and right-click and select "Select Similarity", so that all the texts to be dug are selected;
4. After selecting the text to be extracted, cut and paste it with the keyboard shortcut "Ctrl+X", and then extract the text with "Ctrl+V". Now the text is in a separate layer;
5. Delete the original background layer, click "File" and select "Save As" to save the extracted text and use it in other places.
1. First open a picture that needs to be deducted. If the part that needs to be deducted is very different from other parts, you can directly extract the picture with the magic wand, click the magic wand, or select the picture with a pen.
2. Check the picture with a magic wand. Pointing the magic wand at the blank of the picture will select the same part as the blank.
3. Select the picture to be processed. Right-click on the picture and select Reverse, so that you can get a logo of the picture.
4. If you choose free transformation, you will select the picture in reverse, and there will be a changing scroll bar. If this logo is relatively large, you can right-click on the logo and select Free Transform.
5. Select a foot with the mouse and drag it to reduce the picture. When dragging, you need to hold down the shift key at the same time, so as to ensure that the picture will not be deformed.
6. Check the image size. Adjust the size in the view to 100%, and you can see the actual size of the part to be deducted.
7. Copy and paste the modified clip-and-paste picture (using the shortcut key Ctrl+C/ctrl+V) to another picture, and you can see that the size is the same.
