$ico_pic 是你要给图片加水印的水印图片,其它的参数都有详细的说明,如果你正在找这类代码可以下载保存成php文件,再利用后面说的调用方法来调用生成水印图片类代码.
php图片增加中文与图片水印代码如下:
- <?php
- class smallpic{
- private $src_pic;//原图
- private $ico_pic = "003.png";//水印图
- private $ico_text = "水印";//水印文字
- private $small_width;//缩略图宽度
- private $small_height;//缩略图高度
- private $is_ico_pic = true;//是否加图片水印
- private $is_text = true;//是否加文字水印
- private $src_x = 20;//水印在原图的x坐标
- private $src_y = 20;//水印在原图的y坐标
- private $ut = "utf-8";//文字编码
- private $font_color = "#990000";//文字水印颜色
- private $samll_pic_name = "smallpic";//小图的名称
- private $big_pic_name = "bigpic";//大图的名称
- function __construct($src_pic,$small_width,$small_height){
- $this->checkfile($src_pic);
- $this->checkfile($this->ico_pic);

- }
