/*
* 功能：圖片加水印 (水印支持圖片或文字)
* 參數：
* $groundImage 背景圖片，即需要加水印的圖片，暫只支持GIF,JPG,PNG格式；
* $waterPos 水印位置，有10種狀態，0為隨機位置；
* 1為頂端居左，2為頂端居中，3為頂端居右；
* 4為中部居左，5為中部居中，6為中部居右；
* 7為底端居左，8為底端居中，9為底端居右；
* $waterImage 圖片水印，即作為水印的圖片，暫只支持GIF,JPG,PNG格式；
* $waterText 文字水印，即把文字作為為水印，支持ASCII碼，不支持中文；
* $textFont 文字大小，值為1、2、3、4或5，默認為5；
* $textColor 文字顏色，值為十六進制顏色值，默認為#FF0000(紅色)；
*
* 注意：Support GD 2.0，Support FreeType、GIF Read、GIF Create、JPG 、PNG
* $waterImage 和 $waterText 最好不要同時使用，選其中之一即可，優先使用 $waterImage。
* 當$waterImage有效時，參數$waterString、$stringFont、$stringColor均不生效。
* 加水印後的圖片的文件名和 $groundImage 一樣。
