color QR code

[mrdraft]

Hallo everyone,
I'd like to change the color of the QR code, but I really cannot manage, I tried to change the values of the "moduleValues", but the color of the "black" pixels does not change.
Am I missing something?

thanks in advance

Hey, first things first, which version and output type are you using? Also, do you have an snippet of your code perhaps?

except imageBase64 which I need true

Can you please post a full code snippet of your code so that I can reproduce the issue?

surem here:

 $moduleValues = ['moduleValues' => [
            // finder
            (QRMatrix::M_FINDER << 8)     => [0, 63, 255],    // dark (true)
            (QRMatrix::M_FINDER_DOT << 8) => [0, 63, 255],  // finder dot, dark (true)
            QRMatrix::M_FINDER            => [255, 255, 255], // light (false), white is the transparency color and is enabled by default
            // alignment
            (QRMatrix::M_ALIGNMENT << 8)  => [0, 63, 255],
            QRMatrix::M_ALIGNMENT         => [255, 255, 255],
            // timing
            (QRMatrix::M_TIMING << 8)     => [0, 63, 255],
            QRMatrix::M_TIMING            => [255, 255, 255],
            // format
            (QRMatrix::M_FORMAT << 8)     => [0, 63, 255],
            QRMatrix::M_FORMAT            => [255, 255, 255],
            // version
            (QRMatrix::M_VERSION << 8)    => [0, 63, 255],
            QRMatrix::M_VERSION           => [255, 255, 255],
            // data
            (QRMatrix::M_DATA << 8)       => [0, 63, 255],
            QRMatrix::M_DATA              => [255, 255, 255],
            // darkmodule
            QRMatrix::M_LOGO              => [255, 255, 255],
        ]];

        $this->options = new QROptions([
            'version'  => $qrOptions['version'], // using 3
            'eccLevel' => $qrOptions['eccLevel'],  // using QRCode::ECC_L
            'imageBase64' => $qrOptions['imageBase64'], // true
            'imageTransparent' => $qrOptions['imageTransparent'], // true
            $moduleValues
        ]);

   try {
            $qrImage = new QRImage($this->options, (new QRCode($this->options))->getMatrix($data));
            $qrcodeString = $qrImage->dump($file);
        } catch (QRCodeDataException|QRCodeException $e) {
            $this->logging->log('error', 'QrCode error', $e->getMessage());
        }

        return $qrcodeString;

Ok, the issue I'm seeing is that the options array is not properly constructed:

 $moduleValues = ['moduleValues' => [
    // ...
 ]];
 
 $this->options = new QROptions([
            $moduleValues
]);

This will create an array with a numerical key at the root and it will contain one element, moduleValues, that contains the actual value.
Instead it should be:

 $moduleValues =  [
    // ...
 ];
 
 $this->options = new QROptions([
    // ...
    'moduleValues' => $moduleValues,
]);

I fixed that and ran the code locally and the matrix appeared blue.

use chillerlan\QRCode\Data\QRCodeDataException;
use chillerlan\QRCode\Data\QRMatrix;
use chillerlan\QRCode\Output\QRImage;
use chillerlan\QRCode\QRCode;
use chillerlan\QRCode\QRCodeException;
use chillerlan\QRCode\QROptions;

require_once __DIR__.'/../vendor/autoload.php';

$moduleValues = [
		// finder
		(QRMatrix::M_FINDER << 8)     => [0, 63, 255],    // dark (true)
		(QRMatrix::M_FINDER_DOT << 8) => [0, 63, 255],  // finder dot, dark (true)
		QRMatrix::M_FINDER            => [255, 255, 255],
		// light (false), white is the transparency color and is enabled by default
		// alignment
		(QRMatrix::M_ALIGNMENT << 8)  => [0, 63, 255],
		QRMatrix::M_ALIGNMENT         => [255, 255, 255],
		// timing
		(QRMatrix::M_TIMING << 8)     => [0, 63, 255],
		QRMatrix::M_TIMING            => [255, 255, 255],
		// format
		(QRMatrix::M_FORMAT << 8)     => [0, 63, 255],
		QRMatrix::M_FORMAT            => [255, 255, 255],
		// version
		(QRMatrix::M_VERSION << 8)    => [0, 63, 255],
		QRMatrix::M_VERSION           => [255, 255, 255],

		(QRMatrix::M_DATA << 8)       => [0, 63, 255],
		QRMatrix::M_DATA              => [255, 255, 255],
		// darkmodule
		QRMatrix::M_LOGO              => [255, 255, 255],
];

$options = new QROptions([
	'version'          => 3, // using 3
	'eccLevel'         => QRCode::ECC_L,  // using QRCode::ECC_L
	'imageBase64'      => true, // true
	'imageTransparent' => true, // true
	'moduleValues'     => $moduleValues,
]);

try{
	$qrImage      = new QRImage($options, (new QRCode($options))->getMatrix('test'));
	$qrcodeString = $qrImage->dump();
}
catch(QRCodeDataException|QRCodeException $e){
	$this->logging->log('error', 'QrCode error', $e->getMessage());
}

echo $qrcodeString;

omg, yes. Indeed now it works.
What a silly mistake.

Thank you!
