PHPThumb图片处理实例代码_PHP教程

<?<span php
</span><span //</span><span 加载类库文件</span>
<span require_once</span> 'path/to/ThumbLib.inc.php'<span ;
</span><span //</span><span 实例化类库，传入你要处理的图片的地址可以是网络地址，也可以是本地地址</span>
<span $thumb</span> = PhpThumbFactory::create('http://www.jbxue.com/'<span );
</span><span //</span><span 把图片等比缩小到最大宽度 100px或者最高100px，当只输入一个参数的时候，是限制最宽的尺寸。</span>
<span $thumb</span>->resize(100, 100<span );
</span><span //</span><span 把图片等比缩小到原来的百分数，比如50就是原来的50%。</span>
<span $thumb</span>->resizePercent(50<span );
</span><span //</span><span 截取一个175px * 175px的图片，注意这个是截取，超出的部分直接裁切掉，不是强制改变尺寸。</span>
<span $thumb</span>->adaptiveResize(175, 175<span );
</span><span //</span><span 从图片的中心计算，截取200px * 100px的图片。</span>
<span $thumb</span>->cropFromCenter(200, 100<span );
</span><span //</span><span 截图，前两个参数分别是需要解出的图片的右上角的坐标X,Y。 后面两个参数是需要解出的图片宽，高。</span>
<span $thumb</span>->crop(100, 100, 300, 200<span );
</span><span //</span><span 把图片顺时针反转180度</span>
<span $thumb</span>->rotateImageNDegrees(180<span );
</span><span //</span><span 保存（生成）图片,你可以保存其他格式，详细参考文档</span>
<span $thumb</span>->save( 'NewPath/Of/image.jpg ' );

<span We'll be using phpThumb , the open source PHP script to generate thumbnails on the fly.
Download and extract phpThumb to somewhere in your website folder. Now to use a rounded corner thumbnail of an image, simply use the img tag of HTML with src as
</span><span <</span><span img </span><span src</span><span =&rdquo;phpThumb.php?src=test.jpg&w=200&h=150&fltr[]=ric|20|20&f=png&rdquo; </span><span /></span><span  
Adjust the path to phpThumb according to where you place the phpThumb files.
