kohana 3.0在上传之前调整图片大小？

Question

I want to upload some images to the server, but first of all i want them croped, and resized to some certain dimensions.

Now i am doing the simple upload and save like that:

$header_image = Upload::save($_FILES['sale_picture_header'],NULL,APPPATH.'media'.'/');
$image_header = Model::factory('image');                                
$image_header->name = basename($header_image);
$image_header->save();

(excluding the validation).

How can i crop or resize the image to some desired dimensions, in Kohana 3.0? I couldn't find any relevant documentation regarding that.

Thank you!

Did you try with the image package:

// Resize to 200 pixels on the shortest side
$image->resize(200, 200);

// Resize to 200x200 pixels, keeping aspect ratio
$image->resize(200, 200, Image::INVERSE);

// Resize to 500 pixel width, keeping aspect ratio
$image->resize(500, NULL);

// Resize to 500 pixel height, keeping aspect ratio
$image->resize(NULL, 500);

// Resize to 200x500 pixels, ignoring aspect ratio
$image->resize(200, 500, Image::NONE);
