The FQCN of the custom QROutputInterface

if QROptions::$outputType is set to QROutputInterface::CUSTOM (default: null)

returnResource

Return the image resource instead of a render if applicable.

  • QRGdImage: resource (PHP < 8), GdImage
  • QRImagick: Imagick
  • QRFpdf: FPDF

This option overrides/ignores other output settings, such as QROptions::$cachefile and QROptions::$outputBase64. (default: false)

See also:

  • \chillerlan\QRCode\Output\QROutputInterface::dump()

cachefile

Optional cache file path /path/to/cache.file

Please note that the $file parameter in QRCode::render() and QRCode::renderMatrix() takes precedence over the QROptions::$cachefile value. (default: null)

See also:

  • \chillerlan\QRCode\QRCode::render()
  • \chillerlan\QRCode\QRCode::renderMatrix()

outputBase64

Toggle base64 data URI or raw data output (if applicable)

(default: true)

See also:

  • \chillerlan\QRCode\Output\QROutputAbstract::toBase64DataURI()

eol

Newline string

(default: PHP_EOL)

bgColor

Sets the image background color (if applicable)

  • QRImagick: defaults to "white"
  • QRGdImage: defaults to [255, 255, 255]
  • QRFpdf: defaults to blank internally (white page)

if QROptions::$scale is less than 20, the image will be upscaled internally, then the modules will be drawn using imagefilledellipse() and then scaled back to the expected size

No effect in: QREps, QRFpdf, QRMarkupHTML

See also:

circleRadius

Specifies the radius of the modules when QROptions::$drawCircularModules is set to true

(default: 0.45)

keepAsSquare

Specifies which module types to exclude when QROptions::$drawCircularModules is set to true

(default: [])

connectPaths

Whether to connect the paths for the several module types to avoid weird glitches when using gradients etc.

See also:

excludeFromConnect

Specify which paths/patterns to exclude from connecting if QROptions::$connectPaths is set to true
