For example, Photoshop slashes the image as follows:

1, open the picture in Photoshop, click the picture maximization button, and use the cropping tool to pull out the cropping box along the edge of the picture;

2. Place the cursor outside the clipping box. When the cursor becomes a curved double arrow, drag the cursor to rotate the image, pay attention to observation, and stop when it rotates to a suitable position;

3. Double-click the mouse to confirm the image formation after cutting;

4. Click on the picture to rotate the canvas, and rotate it 90 degrees clockwise;

5. Repair the four corners with the imitation stamp tool;

6. Adjust the curve slightly, and the image is normal.
