PHP rounded corner Image

I used it in my work. I wrote one myself and shared it with people who need it. The class definition is in the front, and the second line is called.

 

Advantages:

External Image not required

Supports PNG transparency

Customizable Corner radius

 

Disadvantages:

Only one transparent color can be specified.
