这款程序给图片加文字水印时是调用 了C://WINDOWS//Fonts////SIMHEI.TTF字体,给图片加水印时就可以自定图片,实例代码如下:
- $image->wprint_img();//执行图片水印
- $image->wprint_string();//执行文字水印
- class editimage{
- private $imagefile;//图片文件
- private $smallimg;//水印图片
- private $string;//水印文字
- private $position;//存放位置
- private $dst_x=600;//原始图片打水印x坐标
- private $dst_y=0;//原始图片打水印y坐标
- private $str_x=450;
- private $str_y=200;
- private $font="c:windows ontssimhei.ttf";//原始图片打水印字体路径
- private $imgej;// imagecolorallocate后的变量
- function __get($value){
- return $this->$value;
- }
- function __set($property,$value){
- $this->$property=$value;
- }
- /**
- * 构造函数初始化
- *
- * @param string $imagefile 被上水印的文件
- * @param string $smallimg 水印文件
- * @param string $string 水印文字
- * @param string $position 存放位置
- * @param int $dst_x 被上水印的图片x
- * @param int $dst_y 被上水印的图片y

- function __construct($imagefile,$smallimg='',$string=''){//,$position='',$dst_x=0,$dst_y=0
- $this->imagefile=$imagefile;

- }else{
- return "水印图片不存在!";
- }
- }
- //水印文字处理
- function wprint_string(){

- //使用方法如下:
- $image=new editimage("d90.gif","hknmtt.png","我的d90");
- $image->wprint_img();//执行图片水印
- $image->wprint_string();//执行文字水印,开源代码Vevb.com
- $image->choose_imgouttype();
