Resolves #4708 - adding transparent background support to barcode

[steverhoades]

There are currently no tests for this, the code in general here could probably be cleaned up a bit. Also, I have noticed that there is currently no 2.0 documentation on Barcode and ZendPdf doesn't exist.

Example Usage for Image:

        // Only the text to draw is required
        $barcodeOptions = array('text' => 'ZEND-FRAMEWORK');

        // No required options
        $rendererOptions = array('imageType'=> 'png', 'transparentBackground' => true);

        \Zend\Barcode\Barcode::factory(
            'code39', 'image', $barcodeOptions, $rendererOptions
        )->render();

Example Usage for SVG:

        // Only the text to draw is required
        $barcodeOptions = array('text' => 'ZEND-FRAMEWORK');

        // No required options
        $rendererOptions = array('transparentBackground' => true);

        \Zend\Barcode\Barcode::factory(
            'code39', 'svg', $barcodeOptions, $rendererOptions
        )->render();

Want to follow this up with a quick note, that it is discouraged to output barcodes that are NOT black on white. They may still work with your scanner though.

@steverhoades We deprecated ZendPdf with ZF2; too difficult to maintain, as the spec is constantly evolving, and it's a very difficult thing to get the various features right.

We do have the old Barcode documentation -- I suspect it's simply not linked in the TOC and/or index, which is why you cannot see it in the rendered manual.

@steverhoades Any chance I can get some unit tests?

[steverhoades]

@weierophinney Actually, I think I may have been wrong with with the documentation, it may be in 2.

Should we remove the PDF Renderer for barcode?

I'll work on getting some unit tests in to support this.

[weierophinney]

@steverhoades Let's deprecate the PDF renderer for the next minor revision (2.3.0), and then we can remove in 3.

Matthew,

So sorry! Been on vacation with the Family for the Holidays. I'll look at
this as soon as I get settled in to see what is left.

Happy New Year!
