使用ImageMagick上载时调整图像大小/缩小/缩略图

问题描述：

我有HTML表单来上传图片，我想在上传过程中调整大小/缩小/缩略图.

i have html form to upload images , I want to Resize-reduce/thumbnail during the uploading process.

$uploadDir= "/uploads";
$imageName= $_FILES['image']['name'];
$tempPath = $_FILES['image']['tmp_name'];

move_uploaded_file ($tempPath,$uploadDir);

缩小大小:

convert $imageName -resize 800x600 -strip -quality 50 -interlace line output.jpg

缩略图:

convert $imageName -resize x120 -gravity center -crop 120x120+0+0 +repage thumb_output.jpg

这是第一次使用Imagick！

this is the first time using Imagick !

使用nohup在后台使用exec()运行这些命令.

run these commands using exec() in background using nohup.

exec('nohup convert ... > /dev/null &');
