I did use the same javascript cropper + sfThumbnailPlugin and
Imagemagick. As you said, I had to implement cropping + resizing in
order to make all that work. I was planning for some time now to
commit those changes to the plugin so I will do that now and let you
take a look at SVN for the changes I have made.
For example, I use it like this:
$coords = array(
'x1' => $this->getRequestParameter('x1'),
'x2' => $this->getRequestParameter('x2'),
'y1' => $this->getRequestParameter('y1'),
'y2' => $this->getRequestParameter('y2')
);
$thumbnail = new sfThumbnail(150, 150, false, true, 75,
'sfImageMagickAdapter', array('method' => 'custom', 'coords' =>
$coords));
$thumbnail->loadFile($original);
$thumbnail->save($thumb, 'image/jpeg');
Valid values for 'method' are: shave_all, shave_bottom, custom.
Shave_all: It will crop the image from all sides until it gets to the
desired proportions and then it will resize it to the final
dimensions.
Shave_bottom: Will do like above but it will not crop the image from
the top which helps with pictures of people so that it does not cut
the head.
Custom: Is exactly what you need for this javascript cropper as the
cropper sends back to your ajax the coordinates of the thumb.
I am committing it out so check it out when you read this email.
