## Usage

### Generate Base64

```php
use Salla\ZATCA\GenerateQrCode;
use Salla\ZATCA\Tags\InvoiceDate;
use Salla\ZATCA\Tags\InvoiceTaxAmount;
use Salla\ZATCA\Tags\InvoiceTotalAmount;
use Salla\ZATCA\Tags\Seller;
use Salla\ZATCA\Tags\TaxNumber;

$generatedString = GenerateQrCode::fromArray([
    new Seller('Salla'), // seller name        
    new TaxNumber('1234567891'), // seller tax number
    new InvoiceDate('2021-07-12T14:25:09Z'), // invoice date as Zulu ISO8601 @see https://en.wikipedia.org/wiki/ISO_8601
    new InvoiceTotalAmount('100.00'), // invoice total amount
    new InvoiceTaxAmount('15.00') // invoice tax amount
    // TODO :: Support others tags
])->toBase64();

// > Output
// AQVTYWxsYQIKMTIzNDU2Nzg5MQMUMjAyMS0wNy0xMlQxNDoyNTowOVoEBjEwMC4wMAUFMTUuMDA=
```

### Generate Plain

```php
use Salla\ZATCA\GenerateQrCode;
use Salla\ZATCA\Tags\InvoiceDate;
use Salla\ZATCA\Tags\InvoiceTaxAmount;
use Salla\ZATCA\Tags\InvoiceTotalAmount;
use Salla\ZATCA\Tags\Seller;
use Salla\ZATCA\Tags\TaxNumber;

$generatedString = GenerateQrCode::fromArray([
    new Seller('Salla'), // seller name        
    new TaxNumber('1234567891'), // seller tax number
    new InvoiceDate('2021-07-12T14:25:09Z'), // invoice date as Zulu ISO8601 @see https://en.wikipedia.org/wiki/ISO_8601
    new InvoiceTotalAmount('100.00'), // invoice total amount
    new InvoiceTaxAmount('15.00') // invoice tax amount
    // TODO :: Support others tags
])->toTLV();
```
<p align="right">(<a href="#top">back to top</a>)</p>

### Render A QR Code Image

You can render the tags as QR code image easily


```php
use Salla\ZATCA\GenerateQrCode;
use Salla\ZATCA\Tags\InvoiceDate;
use Salla\ZATCA\Tags\InvoiceTaxAmount;
use Salla\ZATCA\Tags\InvoiceTotalAmount;
use Salla\ZATCA\Tags\Seller;
use Salla\ZATCA\Tags\TaxNumber;

// data:image/png;base64, .........
$displayQRCodeAsBase64 = GenerateQrCode::fromArray([
    new Seller('Salla'), // seller name        
    new TaxNumber('1234567891'), // seller tax number
    new InvoiceDate('2021-07-12T14:25:09Z'), // invoice date as Zulu ISO8601 @see https://en.wikipedia.org/wiki/ISO_8601
    new InvoiceTotalAmount('100.00'), // invoice total amount
    new InvoiceTaxAmount('15.00') // invoice tax amount
    // TODO :: Support others tags
])->render();

// now you can inject the output to src of html img tag :)
// <img src="$displayQRCodeAsBase64" alt="QR Code" />
```

## Read The QR-Code

The output of QR-Code is not readable for the human 👀, and some of QR-Code readers maybe show a invalid output because this QR-Code will be scan by the ZATCA apps later after the all steps of integration compete.
If you interested to see the output of your final QR-Code Image you can use the following website
