How to PS the image rounded corner shape

Does the landlord mean a border with rounded corners?
Baidu search has many such tutorials.
The following is a brief introduction.
1. Double-click "background image" in the "layer" window in the lower right corner to unlock
2. Right-click "rectangle tool" on the toolbar and select "corner rectangle tool (below the text tool )"
3. Set the attributes of the tool in the option bar under the menu bar. (Change "pattern tool" to "path" and "radius" to set the Radian of the rounded corner. The larger the value is, the closer the angle is)
4. Drag the desired size in the figure. ctrl + press enter to create a constituency. ctrl + shift + I reverse select the constituency. Then press Del to delete the constituency.
5. The storage is in PNG format.

Note:
1. The rounded rectangle tool is a path tool rather than a selection tool (LZ uses a selection tool)
2. the rounded rectangle tool contains the following six shapes: rectangle, rounded corner, elliptical shape, polygon, straight line, and custom shape.

PS How can I change the image shape to a rounded rectangle? Graph

Ps has a rounded rectangle tool (shortcut: U)
After selecting the rounded rectangle tool, adjust the angle of the rounded corner using the radius value on the toolbar.
Draw the rectangular path of the rounded corner on the graph.
Ctrl + Enter into the selection area, Ctrl + Shift + I invert selection, Delete the corner
Save it ~
If the image is saved as jpg, the deleted corner is white.
Save as png, And the deleted part will become transparent ~ (But remember to delete the background layer together)
This is probably the case. If you have any questions, I will try my best to answer them ~
