php+jquery在线切图代码[防dedecms]

AJAX image cropper - YUI-based

Image :

HTML Blog

上面为index.php文件
根据x,y,来用php重新绘图

// get variables
$imgfile = $_GET['image'];
$cropStartX = $_GET['cropStartX'];
$cropStartY = $_GET['cropStartY'];
$cropW = $_GET['cropWidth'];
$cropH = $_GET['cropHeight'];

// Create two images
$origimg = imagecreatefromjpeg($imgfile);
$cropimg = imagecreatetruecolor($cropW,$cropH);

// Get the original size
list($width, $height) = getimagesize($imgfile);

// Crop
imagecopyresized($cropimg, $origimg, 0, 0, $cropStartX, $cropStartY, $width, $height, $width, $height);

// force download nes image
header("Content-type: image/jpeg");
header('Content-Disposition: attachment; filename="'.$imgfile.'"');
imagejpeg($cropimg);

// destroy the images
imagedestroy($cropimg);
imagedestroy($origimg);
?>

这里是图片上的，

if(!empty($_FILES["uploadImage"])) {
// get file name
$filename = basename($_FILES['uploadImage']['name']);

// get extension
$ext = substr($filename, strrpos($filename, '.') + 1);

// check for jpg only
if ($ext == "jpg") {
// generate unique file name
$newName = 'images/'.time().'.'.$ext;

// upload files
if ((move_uploaded_file($_FILES['uploadImage']['tmp_name'], $newName))) {

// get height and width for image uploaded
list($width, $height) = getimagesize($newName);

// return json data
echo '{"image" : "'.$newName.'", "height" : "'.$height.'", "width" : "'.$width.'" }';
}
else {
echo '{"error" : "An error occurred while moving the files"}';
}
}
else {
echo '{"error" : "Invalid image format"}';
}
}
?>
