Image Resize & Rotation

Hi

I have 2 scripts, one for Image rotation and other image resize and they both are working.

Image resize scripts load the picture and resize it and Image rotation rotate the image by 90 deg. They are two differennt files i.e. resize.php and rotate.php.

What I want to do is to combine both rotate.php & resize.php files, so when the script resized the image than it will call rotate script to rotate the image and display it on the screen.. I hope I am making sence.. I am finding hard to explain.. If u dont understand anything please let me know..
*************************
Code for rotate.php
[php]<?php
// File and rotation
$filename = 'image.png';
$degrees = 18;

// Content type
header('Content-type: image/png');

// Load
$source = imagecreatefrompng($filename);

// Rotate
$rotate = imagerotate($source, $degrees, 0);

// Output
imagepng($rotate);
?>
============================
Code for resize.php
<?php
$src_img = imagecreatefrompng('image.png');
$srcsize = getimagesize('image.png');
$dest_x = 200;
$dest_y = (200 / $srcsize[0]) * $srcsize[1];
$dst_img = imagecreatetruecolor($dest_x, $dest_y);
imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0,
$dest_x, $dest_y, $srcsize[0], $srcsize[1]);
header("content-type: image/png");
imagepng($dst_img);
imagedestroy($src_img);
imagedestroy($dst_img);
?>[/php]thanks

Please enclose any code within the proper code tags. See the Posting Guidelines on how to do that.

Don't output $rotate and use it as:
$src_img = $rotate;

well i changed the output "$src_img = $rotate;" but it still did not work... Just to let know there are two different files

File 1 is reseize.php

File 2 is rotate.php

thanks

[php]<?php
$src_img = imagecreatefrompng('image.png');
$srcsize = getimagesize('image.png');
$dest_x = 200;
$dest_y = (200 / $srcsize[0]) * $srcsize[1];
$dst_img = imagecreatetruecolor($dest_x, $dest_y);
imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $dest_x, $dest_y, $srcsize[0], $srcsize[1]);
imagedestroy($src_img);

//header("content-type: image/png");
//imagepng($dst_img);
//?><?php
// File and rotation
//$filename = 'image.png';
$degrees = 18;

// Load
//$source = imagecreatefrompng($filename);

// Rotate
$rotate = imagerotate($dst_img, $degrees, 0); //CHANGED
imagedestroy($dst_img);

// Content type
header('Content-type: image/png');

// Output
imagepng($rotate);
imagedestroy($rotate);
?>[/php]
See if this works.

No, it won't work. You will have to first check which image it is, then apply the corrosponding imagecreatefromXXX() function.
[php]<?php
$srcsize = getimagesize('image.png');
switch ($srcsize[mime])
{
case ('image/gif'):
$src_img = imagecreatefromgif('image.gif');
break;
case ('image/png'):
$src_img = imagecreatefrompng('image.png');
break;
case ('image/jpeg'):
$src_img = imagecreatefromjpeg('image.jpg');
break;
default:
return;
}[/php]
* make sure if its imagecreatefromjpeg or imagecreatefromjpg
