Finally, I think it is necessary to add a watermark to the image principle:
Get uploaded file information, create a true color image, assign a color scheme, and populate the image.
Create a graphic by determining the type of file, and then copy it to the original set of graphics, fill and build the rectangle to write imagestring () or the original image
The program to determine the watermark type: One is a string, another is to add a graphic object on top.
