Creating And Cropping An Image

[dweb]

Hi

 

I really could do with someone's help, i've tried a ton of things and nothing seems to work.

 

I have a HTML page which contains a 200px by 500px div

 

Behind that div, I have an image, which can be dragged around, resized and i've put a rotate tool in too.

 

Once the user is happy, they click a button and using javascript I store the following in the database

 

Width = the new width

Height = the new height

Left = how far left the image was dragged (ie: -100)

Top = how far from the top the image was dragged (ie: 20)

Angle = the rotation in degrees

Image = url of image (ie: ../images/photos/abcd.jpg)

 

The "top" and "left" can be positive values (ie: 300) or negative values (ie: -100)

 

I have stored those values as vars (ie: $var_rotate_value), what I want to do, is using GD library, replicate what the user did and save a copy of the image that was positioned inside the div, cropping everything around the outside of the div

 

I've tried so many things and nothing is working for me

 

It either shows the wrong size, or it doesn't rotate correctly, or the position is way off

 

I have attached an image to try and show you what im trying to do

 

The code i'm using and hacking around is;

 

$filename = '../images/photos/abcd.jpg';
$nfile = $var_photo_url_value;

$degrees = $var_rotate_value;

$source = imagecreatefromjpeg($filename);
$rotate = imagerotate($source, $degrees, 0);
imagejpeg($rotate, $nfile, 100);
imagedestroy($rotate);

$div_area_width = 200;
$div_area_height = 500;

list($width, $height) = getimagesize($filename);

$from_left = $var_left_value;
$from_top = $var_top_value;

$new_width = $var_width_value;
$new_height = $var_height_value;
$image_p = imagecreatetruecolor($div_area_width, $div_area_height);
$image = imagecreatefromjpeg($nfile);

imagecopyresampled($image_p, $image, 0, 0, $from_left, $from_top, $new_width, $new_height, $width, $height);
imagejpeg($image_p, $nfile, 100);
imagedestroy($image_p);

 

Can someone help please?
