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

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

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Borderpng = 'cloud.png';
$thumb -> Createthumb('gfx/image.jpg');
?>
13、指定区域裁剪图片

$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Cropimage = array(2,0,20,20,35,35);
$thumb -> Createthumb('gfx/image.jpg');
?>

$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Shadow = true;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Cropimage = array(2,0,20,20,35,35);

css圆角问题 ie浏览器下设置圆角后，圆角哪里不透明，显示的是tab的颜色，如图border-radius:5px
ie下另写程序 圆角是好的，如下图
出现这种问题，估计是easyui中某个样式引起的吧~
解决方案：一种办法是把tab的背景 渐变一下，设置header-gradient-from，颜色和背景色相差无几，不过不好看
但有个缺陷是 无背景条的tab圆角有些问题 如上图中左上角的tab
这时就需要重写一下有背景的tab样式，效果如下
.tabs li.tabs-selected a.tabs-inner {
background-color: #ffffff;
color: #0E2D5F;
background: -webkit-linear-gradient(top,#cccccc,#ffffff 100%);
background: -moz-linear-gradient(top,#cccccc,#ffffff 100%);
background: -o-linear-gradient(top,#cccccc,#ffffff 100%);
background: linear-gradient(to bottom,#cccccc,#ffffff 100%);
background-repeat: repeat-x;
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#cccccc,endColorstr=#ffffff,GradientType=0);
}
utf-8 转换圆角怎么实现? 用php写的<?php
echo ' web-root = '.$_SERVER['DOCUMENT_ROOT'].'<br>';
echo ' current-file = '.__FILE__.'<br>';
echo ' current-dir = '.dirname(__FILE__).'<br>';
echo ' http-root = '.$_SERVER['HTTP_HOST'].'<br>';
echo ' web-position = '.$_SERVER['PHP_SELF'].'<br>';
$file='c:/webroot/index.php';
echo ' file-position = '.$file.'<br>';
$fileWebAddress='http://'.str_replace($_SERVER['DOCUMENT_ROOT'],$_SERVER['HTTP_HOST'],$file);
echo ' file-web-position = '.$fileWebAddress.'<br>';
?>
php添加超链接变透明了，如何解决？在A标签上增加CSS代码 ，下边给出的是红色的你可以试一试，有问题可以再和我联系。
style="color: red;"
用php怎么做圆形头像做法有两种：
第一种：就是用个透明的图片遮挡做头像，显示圆角头像。原理就是在头像上覆盖一张透明的图片，把四个角颜色设置成页面的背景颜色，中间透明。
第二种：在你上传头像的时候程序自动裁剪成圆的，保留原图片和新裁剪的图片就ok了。
希望能帮助到你...
php怎么输出背景透明的图片？php可以使用GD库或者ImageMagick工具生成png或者gif的背景透明图片.推荐使用ImageMagick.
这里有范例
准备一张png图片,放到php文件的目录,运行看看效果.
<?php
/* Read the image */
$im = new Imagick("test.png");
/* Thumbnail the image */
$im->thumbnailImage(200, null);
/* Create a border for the image */
$im->borderImage(new ImagickPixel("white"), 5, 5);
/* Clone the image and flip it */
$reflection = $im->clone();
$reflection->flipImage();
/* Create gradient. It will be overlayed on the reflection */
$gradient = new Imagick();
/* Gradient needs to be large enough for the image and the borders */
$gradient->newPseudoImage($reflection->getImageWidth() + 10, $reflection->getImageHeight() + 10, "gradient:transparent-black");
/* Composite the gradient on the reflection */
$reflection->compositeImage($gradient, imagick::COMPOSITE_OVER, 0, 0);
/* Add some opacity. Requires ImageMagick 6.2.9 or later */
$reflection->setImageOpacity( 0.3 );
/* Create an empty canvas */
$canvas = new Imagick();
/* Canvas needs to be large enough to hold the both images */
$width = $im->getImageWidth() + 40;
$height = ($im->getImageHeight() * 2) + 30;
$canvas->newImage($width, $height, new ImagickPixel("black"));
$canvas->setImageFormat("png");
/* Composite the original image and the reflection on the canvas */
$canvas->compositeImage($im, imagick::COMPOSITE_OVER, 20, 10);
$canvas->compositeImage($reflection, imagick::COMPOSITE_OVER, 20, $im->getImageHeight() + 10);
/* Output the image*/
header("Content-Type: image/png");
echo $canvas;
?>
