[RESOLVED] Using Image_Barcode within GD script

middleman666

Hey All,

I need a barcode, on top of an off white coloured rectangle and for the whole image to be rotated 90 degrees clockwise.

I have the following code:

<?php
require_once("Image/Barcode.php");

//$code = strtoupper($_GET['code']);
$code = '15101967';

$width = 280;
$height = 40;

$im = imagecreate($width, $height);

$offwhite = imagecolorallocate($im, 249, 249, 249);

$im = imagefilledrectangle($im, 0, 0, $width, $height, $offwhite);

$im = Image_Barcode::draw($code, 'int25', 'png', false);

header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>

That currently just returns the barcode that Image_Barcode builds ignoring the off white rectangle.

Also played around with imagerotate(), but everytime I did it returned nothing so not sure where to put this in the code.

Anyone know where I'm going wrong?

Cheers

Ok, managed to get rotate working with the barcode:

<?php
require_once("Image/Barcode.php");

$code = '123456';

$im = Image_Barcode::draw($code, 'int25', 'png', false);
$im = imagerotate($im, 90, 0);

header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>

Still none the wiser with giving it an off white background, I think the file building the barcode must be doing that.

Well, I can see why your original code didn't work. You created an image, specified a grey colour for it, and then on the very next line you threw it away and replaced it with an image created by this Image_Barcode class you're using.

What to do about that depends entirely on what functionality that class offers through its interface. Maybe it has something to allow drawing barcodes onto existing images, or specifying which colours to use.

Cheers Weedpacket, I've never really understood how to put together GD scripts, I thought $im was treated as a kind of canvas which parts could be added to but obviously not the case!

My server guys gave me access to the Image_barcode PEAR package configuration files so I was able to see that the barcode was defining a white background before returning the barcode, I just changed that to my off grey colour and everything looks fine.

Cheers for the help!
