No work $options->bgColor

[alex-l-iwpdev]

Issue description

Lots of questions
1 I can't set the background color for PNG
2 I can't choose the size normally, for example 500x500

Expected behavior

Qr code PNG 500x500 with black background and for example white Qr

Code sample

$options                    = new QROptions;
		$options->version           = 7;
		$options->outputType        = QROutputInterface::IMAGICK;
		$options->imagickFormat     = 'png';
		$options->bgColor           = '#000000';
		$options->transparencyColor = '#000000';
		$options->outputBase64      = false;
		$options->eccLevel          = QRCode::ECC_L;
		$options->quality           = 90;
		$options->scale             = 10;
		$options->outputBaseSize    = 50;
		$options->imageTransparent  = false;

		if ( ! empty( $qr_option ) ) {
			$options->moduleValues = [
				QRMatrix::M_DARKMODULE     => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_SEPARATOR_DARK => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_TIMING_DARK    => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_FORMAT_DARK    => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_VERSION_DARK   => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_QUIETZONE_DARK => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_LOGO_DARK      => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_DATA_DARK      => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_FINDER_DARK    => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_ALIGNMENT_DARK => $qr_option['color']['text'] ?? '#000000',
				QRMatrix::M_FINDER_DOT     => $qr_option['color']['text'] ?? '#000000',
			];
		}

		try {
			( new QRCode( $options ) )->render( $string_url, $file_path );
		} catch ( Throwable $e ) {
			return [
				'error'   => true,
				'message' => $e->getMessage(),
			];
		}

Library version

latest

Additional context

why is there no normal resize function that accepts exact sizes

[codemasher]

This is not a bug. If you set both, bgColor and transparencyColor to the same value, the background will become transparent. Also, there is no such option outputBaseSize - the scale value determines the size of a single QR pixel and the final size of the QR image depends on the side length (QR pixels * scale). If you want the QR image in a certain size, you will have to resize it by yourself. You can return the Imagick instance instead of the image and modify the output then.
