PHP GD library can add multiple watermarks to one picture.Is there a plug-in that can catch it?
The simplest way is to make the watermark text into the most transparent picture, use picture synthesis, cover the watermark picture on the picture, and merge the two pictures.http://www.oschina.net/code/s...
Do you want to add multiple watermarks to one picture? Or do you want to use a plug-in to capture how many watermarks a picture has?
