jQuery+PHP实现上传裁剪图片

$width = $width-($width+$x-$imgize[0]);
}

if(($height+$y)>$imgize[1]){
$height = $height-($height+$y-$imgize[1]);
}

//创建源图的实例
$src = imagecreatefromstring(file_get_contents($file));

//創建一個圖像
$new_image = imagecreatetruecolor($info[0], $info[1]);

//分配颜色
$color = imagecolorallocate($new_image,255,255,255);
//定义为透明色
imagecolortransparent($new_image,$color);
//填充图片
imagefill($new_image,0,0,$color);

//拷贝图片并保存成指定大小
imagecopyresized($new_image, $src, 0, 0, $x, $y, $info[0], $info[1], $width, $height);

//保存

if(false==$cover){
$file = rtrim(dirname($file),'/').'/c_'.basename($file);
$save_file[] = $file;
}

imagejpeg($new_image,$file);

imagedestroy($new_image);
imagedestroy($src);

$i++;
}

if(false==$cover){
return $save_file;
}else{
return $i;
}
}
