PHP Plus Watermark Code support text and image Watermark _php Tutorial

PHP plus picture watermark, Text watermark Class code, PHP plus watermark class, support the text image watermark Transparency settings, watermark picture background transparent. Write a class of their own, because the development of a set of CMS to use, the total feeling of the internet is not comfortable, I hope you also like this class, followed by the use of class methods.
