Preserve transparency after rotate

[audiopro]

The rotation and display work on this small script but how do I keep transparency. According to the docs there is a 4th var in the rotate command to control transparency but however I add the var the script throws an error. (too many vars)

<?php
ini_set('display_errors',1); 
error_reporting(E_ALL|E_STRICT); 

$img_name='images/dirarr2.png';
$Rotat=45;
$Rotat=360-$Rotat;
$src_img = ImageCreateFrompng($img_name);
$BackCuller = imagecolorallocate($src_img, 0,0,0);

[red]$Rotate=imagerotate ($src_img , $Rotat, $BackCuller);[/red]

Imagepng($Rotate);

ImageDestroy($src_img);

?>

Then you have PHP older than 5.1.0.

My host has 4.3.1 installed, is that donkeys years old?

it's certainly 'below' version 5.1.0...

what host do you use?

 

[audiopro]

The host is Easyspace.
I have contacted them and they explain that if they updated PHP, many of the scripts on the shared server would fall over which I suppose is fair comment. I have other domains with them which are on newer servers with later versions of software. I can use those for the odd rotating job.

many hosts install both versions of php and allow you to choose through use of .htaccess files.

it is unlikely that scripts will fall over when migrating from php4 to php5. there are very few functions that are not backwards compatible from php5. Yes, some scripts will error but i would guess much less than 1%.

just fyi here is the list of backward incompatibility. and some of these are not true incompatibilities but simply behaviour changes.
