使用简介
1、基本使用
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
2、动态显示指定大小图片
<?php<br /> include_once('inc/easyphpthumbnail.class.php');<br /> // Your full path to the images<br /> $dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';<br /> // Create the thumbnail<br /> $thumb = new easyphpthumbnail;<br /> $thumb -> Thumbsize = 300;<br /> $thumb -> Createthumb($dir . 'img.jpg');<br />?>登录后复制
3、生成静态多张本地图片
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br /> // Your full path to the images<br /> $dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';<br />$dir_thumbs = str_replace(chr(92),chr(47),getcwd()) . '/thumbs/';<br />if(!is_dir($dir_thumbs)) mkdir($dir_thumbs,0777);<br /> // Create the thumbnail<br /> $thumb = new easyphpthumbnail;<br /> $thumb -> Thumbsize = 600;<br /> $thumb -> Copyrighttext = 'SCUTEPHP.COM';<br /> $thumb -> Copyrightposition = '50% 90%';<br /> $thumb -> Copyrightfonttype = $dir . 'handwriting.ttf';<br /> $thumb -> Copyrightfontsize = 30;<br /> $thumb -> Copyrighttextcolor = '#FFFFFF';<br /> $thumb -> Chmodlevel = '0755';<br />$thumb -> Thumblocation = $dir_thumbs;<br />$thumb -> Thumbsaveas = 'jpg';<br />$thumb -> Thumbprefix = '120px_thumb_';<br />$thumb -> Createthumb(array($dir . '69.jpg', $dir . '70.jpg'), 'file');<br />?>登录后复制
4、图片大小百分比调整及图片旋转
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Thumbsize = 50;<br />$thumb -> Rotate = 90;//指定度数旋转<br />//$thumb -> Fliphorizontal = true; //水平轴旋转<br />//$thumb -> Flipvertical = true; //垂直轴旋转<br />$thumb -> Percentage = true;<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
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

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

8、给缩略图增加框架效果
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Framewidth = 10;<br />$thumb -> Framecolor = '#FFFFFF';<br />$thumb -> Backgroundcolor = '#D0DEEE';<br />$thumb -> Shadow = true;<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
9、给缩略图增加经典相框效果
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Framewidth = 10;<br />$thumb -> Framecolor = '#FFFFFF';<br />$thumb -> Backgroundcolor = '#D0DEEE';<br />$thumb -> Shadow = true;<br />$thumb -> Binder = true;<br />$thumb -> Binderspacing = 8;<br />$thumb -> Clipcorner = array(2,15,0,1,1,1,0);<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
10、给缩略图增加水印效果
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Thumbsize = 300;<br />$thumb -> Framewidth = 10;<br />$thumb -> Framecolor = '#00000';<br />$thumb -> Backgroundcolor = '#000000';<br />$thumb -> Clipcorner = array(2,15,0,1,1,1,1);<br />$thumb -> Watermarkpng = 'watermark.png';<br />$thumb -> Watermarkposition = '50% 50%';<br />$thumb -> Watermarktransparency = 70;<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
11、给缩略图增加短文本及相框
<?php<br />include_once('inc/easyphpthumbnail.class.php');<br />$thumb = new easyphpthumbnail;<br />$thumb -> Thumbsize = 300;<br />$thumb -> Framewidth = 10;<br />$thumb -> Framecolor = '#00000';<br />$thumb -> Borderpng = 'border.png';<br />$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';<br />$thumb -> Copyrightposition = '50% 80%';<br />$thumb -> Copyrightfonttype = 'handwriting.ttf';<br />$thumb -> Copyrightfontsize = 30;<br />$thumb -> Copyrighttextcolor = '#FFFFFF';<br />$thumb -> Createthumb('gfx/image.jpg');<br />?>登录后复制
