qrcode :: PackageName

qrcode package. Use it to import it like this:

usepackage [] qrcode

qrcode commands

data ErrorLevel

The degree of error-correction redundancy to include in the generated code.

Constructors

Low

Error recovery up to 7%.

Medium

Error recovery up to 15%.

Quality

Error recovery up to 25%.

High

Error recovery up to 30%.

Instances

data CodeOptions

Options to use when generating a QR code.

Constructors

CodeOptions

Fields

• includePadding :: Bool

  Whether to include 4 modules of whitespace around the code. False is the default.

• link :: Bool

  Whether, if the code encodes a link, it should be hyperlinked in the PDF document. The default is true. Links will only be generated when the document uses the hyperref package.

• errorLevel :: ErrorLevel

  The desired degree of error-correction redundancy to include in the code. The default is Medium.

Instances

Eq CodeOptions

Methods

(==) :: CodeOptions -> CodeOptions -> Bool

(/=) :: CodeOptions -> CodeOptions -> Bool

Show CodeOptions

Methods

showsPrec :: Int -> CodeOptions -> ShowS

show :: CodeOptions -> String

showList :: [CodeOptions] -> ShowS

defaultOptions :: CodeOptions

The default QR code generation options.

qr :: LaTeXC l => CodeOptions -> Text -> l

Generates a QR code with specified options and content.

This uses the qrcode command from the package, but the identifier qrcode is already in use as the PackageName.

Package Options

draft :: LaTeXC l => l

This package option sets the qrcode package to generate draft-quality placeholders for QR codes.

final :: LaTeXC l => l

This package option (which is the default) sets the qrcode package to generate print-quality QR codes.
