/*
* 功能：PHP图片水印 (水印支持图片或文字)
* 参数：
*$groundImage 背景图片，即需要加水印的图片，暂只支持GIF,JPG,PNG格式；
*$waterPos水印位置，有10种状态，0为随机位置；
*1为顶端居左，2为顶端居中，3为顶端居右；
*4为中部居左，5为中部居中，6为中部居右；
*7为底端居左，8为底端居中，9为底端居右；
*$waterImage图片水印，即作为水印的图片，暂只支持GIF,JPG,PNG格式；
*$waterText文字水印，即把文字作为为水印，支持ASCII码，不支持中文；
*$textFont文字大小，值为1、2、3、4或5，默认为5；
*$textColor文字颜色，值为十六进制颜色值，默认为#FF0000(红色)；
*
* 注意：Support GD 2.0，Support FreeType、GIF Read、GIF Create、JPG 、PNG
*$waterImage 和 $waterText 最好不要同时使用，选其中之一即可，优先使用 $waterImage。
*当$waterImage有效时，参数$waterString、$stringFont、$stringColor均不生效。
*加水印后的图片的文件名和 $groundImage 一样。
