推荐一个简单实用的缩放图片工具 SimpleImage,参考http://www.white-hat-web-design.co.uk/blog/resizing-images-with-
使用方法:

设定宽高,不等比例缩放
代码如下:

$image->load('picture.jpg');
$image->resize(250,400);
$image->save('picture2.jpg');?>

设定宽度,等比例缩放

$image->load('picture.jpg');
$image->resizeToWidth(250);
$image->save('picture2.jpg');?>

设定高度,等比例缩放

$image->load('picture.jpg');
$image->resizeToHeight(500);
$image->save('picture2.jpg');
$image->resizeToHeight(200);
$image->save('picture3.jpg');?>

按比例,缩放至50%

$image->load('picture.jpg');
$image->scale(50);
$image->save('picture2.jpg');?>

缩放后直接输出到屏幕

include('SimpleImage.$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToWidth(150);
$image->output();?>
