easyphpthumbnail类可以处理图像和php生成缩略图支持gif、jpg和png。这个类是免费的，基于100％的php，可用于php4（4.3.11以上）和php5，易于使用，并提供了超过60的功能操作：
提供的功能包括：调整大小，裁剪，旋转，翻转，另存为，阴影，水印，文字，边框，锐化，模糊，水波纹，反射镜，透视，动画，置换贴图和更多！
使用简介
1、基本使用 createthumb('gfx/image.jpg');
?>
2、动态显示指定大小图片 thumbsize = 300;
$thumb -> createthumb($dir . 'img.jpg');
?>
3、生成静态多张本地图片 thumbsize = 600;
$thumb -> copyrighttext = 'scutephp.com';
$thumb -> copyrightposition = '50% 90%';
$thumb -> copyrightfonttype = $dir . 'handwriting.ttf';
$thumb -> copyrightfontsize = 30;
$thumb -> copyrighttextcolor = '#ffffff';
$thumb -> chmodlevel = '0755';
$thumb -> thumblocation = $dir_thumbs;
$thumb -> thumbsaveas = 'jpg';
$thumb -> thumbprefix = '120px_thumb_';
$thumb -> createthumb(array($dir . '69.jpg', $dir . '70.jpg'), 'file');
?>
4、图片大小百分比调整及图片旋转 thumbsize = 50;
$thumb -> rotate = 90;//指定度数旋转
//$thumb -> fliphorizontal = true; //水平轴旋转
//$thumb -> flipvertical = true; //垂直轴旋转
$thumb -> percentage = true;
$thumb -> createthumb('gfx/image.jpg');
?>
thumbsize默认是px像素单位，然而要用百分比的话可以设置percentage属性为ture，rotate属性设置顺时针旋转度数。
5、给缩略图增加背景阴影 backgroundcolor = '#d0deee';
$thumb -> shadow = true;
$thumb -> createthumb('gfx/image.jpg');
?>
6、给缩略图增加圆角效果 backgroundcolor = '#d0deee';
$thumb -> clipcorner = array(2,15,0,0,1,1,0);
$thumb -> createthumb('gfx/image.jpg');
?>
clipcorner属性的7个参数含义
[0]: 0=关闭 1=直角 2=圆角

$thumb -> clipcorner = array(2,15,0,1,1,1,1);
$thumb -> maketransparent = array(1,1,'#0000ff',30);
$thumb -> createthumb('gfx/image.jpg');
?>
8、给缩略图增加框架效果 framewidth = 10;
$thumb -> framecolor = '#ffffff';
$thumb -> backgroundcolor = '#d0deee';
$thumb -> shadow = true;
$thumb -> createthumb('gfx/image.jpg');
?>
9、给缩略图增加经典相框效果 framewidth = 10;
$thumb -> framecolor = '#ffffff';
$thumb -> backgroundcolor = '#d0deee';
$thumb -> shadow = true;
$thumb -> binder = true;
$thumb -> binderspacing = 8;
$thumb -> clipcorner = array(2,15,0,1,1,1,0);
$thumb -> createthumb('gfx/image.jpg');
?>
10、给缩略图增加水印效果 thumbsize = 300;
$thumb -> framewidth = 10;
$thumb -> framecolor = '#00000';
$thumb -> backgroundcolor = '#000000';
$thumb -> clipcorner = array(2,15,0,1,1,1,1);
$thumb -> watermarkpng = 'watermark.png';
$thumb -> watermarkposition = '50% 50%';
$thumb -> watermarktransparency = 70;
$thumb -> createthumb('gfx/image.jpg');
?>
11、给缩略图增加短文本及相框 thumbsize = 300;
$thumb -> framewidth = 10;
$thumb -> framecolor = '#00000';
$thumb -> borderpng = 'border.png';
$thumb -> copyrighttext = 'mywebmymail.com';
$thumb -> copyrightposition = '50% 80%';
$thumb -> copyrightfonttype = 'handwriting.ttf';
$thumb -> copyrightfontsize = 30;
$thumb -> copyrighttextcolor = '#ffffff';
$thumb -> createthumb('gfx/image.jpg');
?>
12、缩略图按指定形状裁剪 thumbsize = 300;
$thumb -> borderpng = 'cloud.png';
$thumb -> createthumb('gfx/image.jpg');
?>
13、指定区域裁剪图片 thumbsize = 300;
$thumb -> cropimage = array(2,0,20,20,35,35);
$thumb -> createthumb('gfx/image.jpg');
?>
