How can I render a Zend_Barcode inside a html page?

问题

One of my application devoloped with Codeignitor and create a barcode using Zend_Barcode library,

reference : http://www.beyondcoding.com/2008/02/21/using-zend-framework-with-codeigniter/

How can I show the barcode on codeignitor view. Tried as ,

// Only the text to draw is required
$barcodeOptions = array('text' => 'NOT-ME');

// No required options
$rendererOptions = array();

// Draw the barcode in a new image,
$imageResource = Zend_Barcode::draw(
    'code39', 'image', $barcodeOptions, $rendererOptions
);

$data['barcode'] = imagejpeg($imageResource, 'barcode.jpg', 100);

// Free up memory
imagedestroy($imageResource); 

in view

<img src="<?php echo $barcode;?>">

but its fails :(

回答1:

Instead of

Zend_Barcode::draw('code39', 'image', $barcodeOptions, $rendererOptions);

Use

Zend_Barcode::render('code39', 'image', $barcodeOptions, $rendererOptions);
