[散分]生活便利小代码,拍照后,批量递归缩放目录图片.
新入手单反一周了,今天终于找上了机会带上老婆老妈去荔枝公园拍了一天的照,回来准备上传至相册,突然发现,每张图片都有点偏大,找工具也很累,直接上网,东拼西凑了点代码.实现将指定目录的图片,按指定大小范围缩放并输出到指定目录(含递归) ,供自己以后处理相片使用. 不多废话了,附代码.

<br />
    header('Content-type:text/html; charset=utf-8');<br />
    require "lib/imgHelper.php";<br />
    $imgHelper = new imgHelper( "dir1" );<br />
    $imgHelper->setOutputDir( "dir2" );<br />
    //默认输出在1024 768 下等比缩放,需要自定义时,$imgHelper->setOutputSize(1440,900);<br />
    $imgHelper->execution();<br />
