EFStyleFunctionParams

public class EFStyleFunctionParams : EFStyleParams

Parameters for function-based QR code styling.

This class defines the styling parameters for function-based QR codes, which use mathematical functions to determine the appearance of data modules. This creates QR codes with dynamic, algorithmically generated patterns.

## Features

Function-based data module generation
Mathematical pattern algorithms
Position detection pattern styling
Icon and backdrop support
Dynamic, algorithmic appearance

## Usage

 let dataParams = EFStyleFunctionParamsData(
     function: .fade(),
     style: .round
 )

 let params = EFStyleFunctionParams(
     icon: icon,
     backdrop: backdrop,
     position: position,
     data: dataParams
 )

 let style = EFQRCodeStyle.function(params)

## Visual Characteristics

Data modules are generated using mathematical functions
Patterns can be fade, wave, or other algorithmic effects
Creates dynamic, visually interesting QR codes
Maintains QR code structure and scannability

                    init(icon:backdrop:position:data:)

Creates function-based QR code styling parameters.

Declaration

Swift

public init(
    icon: EFStyleParamIcon? = nil,
    backdrop: EFStyleParamBackdrop = EFStyleFunctionParams.defaultBackdrop,
    position: EFStyleFunctionParamsPosition = EFStyleFunctionParams.defaultPosition,
    data: EFStyleFunctionParamsData = EFStyleFunctionParams.defaultData
)

Parameters

`icon`	The icon to display in the center of the QR code. Defaults to nil.
`backdrop`	The backdrop configuration. Defaults to default backdrop.
`position`	The position detection pattern configuration. Defaults to default position.
`data`	The data module configuration. Defaults to default data.
