EasyPhpThumbnail PHP图片处理类

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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createthumb('gfx/image.jpg');
?>

2、动态显示指定大小图片

 include_once('inc/easyphpthumbnail.class.php');
 // Your full path to the images
 $dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
 // Create the thumbnail
 $thumb = new easyphpthumbnail;
 $thumb -> Thumbsize = 300;
 $thumb -> Createthumb($dir . 'img.jpg');
?>

3、生成静态多张本地图片

include_once('inc/easyphpthumbnail.class.php');
    // Your full path to the images
    $dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
$dir_thumbs = str_replace(chr(92),chr(47),getcwd()) . '/thumbs/';
if(!is_dir($dir_thumbs)) mkdir($dir_thumbs,0777);
    // Create the thumbnail
    $thumb = new easyphpthumbnail;
    $thumb -> 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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> 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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Createthumb('gfx/image.jpg');
?>

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> 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
[1]: 裁剪比例
[2]: 随机 - 0=关闭 1=开启
[3]: 左上 - 0=关闭 1=开启
[4]: 左下 - 0=关闭 1=开启
[5]: 右上 - 0=关闭 1=开启
[6]: 右下 - 0=关闭 1=开启

$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#0000FF';
$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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> 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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> 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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> 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

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#00000';

$thumb -> Copyrightfonttype = 'handwriting.ttf';
$thumb -> Copyrightfontsize = 30;
$thumb -> Copyrighttextcolor = '#FFFFFF';
$thumb -> Createthumb('gfx/image.jpg');
?>
