Adds an image watermark and a text watermark to an uploaded image.

Keywords:Enterprise Applications

The customer said today that he wants to add a watermark to the image he uploaded to prevent others from stealing the image. He thinks that his images are very important. So...
Well, if the customer has a need, we can satisfy him. I used to write less image operations APIs, so I have never touched on the Image Watermarking function, but for the current network. These are nothing at all. I searched the internet and found several programs. Now I have reconstructed them to meet my requirements. Now I am releasing them, hope you can give some help to friends in need.
