Set the options:
11+
12+
```php
13+
$options = new QROptions;
14+
15+
$options->outputType = QROutputInterface::EPS;
16+
$options->scale = 5;
17+
$options->drawLightModules = false;
18+
// colors can be specified either as [R, G, B] or [C, M, Y, K] (0-255)
19+
$options->bgColor = [222, 222, 222];
20+
$options->moduleValues = [
21+
QRMatrix::M_FINDER_DARK => [0, 63, 255], // dark (true)
22+
QRMatrix::M_FINDER_DOT => [0, 63, 255], // finder dot, dark (true)
23+
QRMatrix::M_FINDER => [233, 233, 233], // light (false)
24+
QRMatrix::M_ALIGNMENT_DARK => [255, 0, 255],
25+
QRMatrix::M_ALIGNMENT => [233, 233, 233],
26+
QRMatrix::M_DATA_DARK => [0, 0, 0],
27+
QRMatrix::M_DATA => [233, 233, 233],
28+
];
29+
```
30+
31+
32+
Render and save to file:
33+
34+
```php

$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
36+
$file = __DIR__.'/qrcode.eps';
37+
38+
(new QRCode($options))->render($data, $file);
39+
```
40+
41+
42+
Push as file download in a browser:
43+
44+
```php
45+
header('Content-type: application/postscript');
46+
header('Content-Disposition: filename="qrcode.eps"');
47+
48+
