Zend_Barcode uses a factory method to create an instance of a
renderer that extends Zend_Barcode_Renderer_RendererAbstract. The
factory method accepts five arguments.
The name of the barcode format (e.g., "code39") (required)
The name of the renderer (e.g., "image") (required)
Options to pass to the barcode object (an array or
Zend_Configobject) (optional)Options to pass to the renderer object (an array or
Zend_Configobject) (optional)Boolean to indicate whether or not to automatically render errors. If an exception occurs, the provided barcode object will be replaced with an Error representation (optional default
TRUE)
Example 58. Getting a Renderer with Zend_Barcode::factory()
Zend_Barcode::factory() instantiates barcode objects and
renderers and ties them together. In this first example, we will use the
Code39 barcode type together with the
Image renderer.
<?php
// Only the text to draw is required
$barcodeOptions = array('text' => 'ZEND-FRAMEWORK');
// No required options
$rendererOptions = array();
$renderer = Zend_Barcode::factory(
'code39', 'image', $barcodeOptions, $rendererOptions
);
Example 59. Using Zend_Barcode::factory() with Zend_Config objects
You may pass a Zend_Config object to the factory in order to
create the necessary objects. The following example is functionally equivalent to
the previous.
<?php
// Using only one Zend_Config object
$config = new Zend_Config(array(
'barcode' => 'code39',
'barcodeParams' => array('text' => 'ZEND-FRAMEWORK'),
'renderer' => 'image',
'rendererParams' => array('imageType' => 'gif'),
));
$renderer = Zend_Barcode::factory($config);
