README

3neti/form-handler-signature captures a drawn signature through an HTML canvas as a step in 3neti/form-flow.

Features

• Mouse and touch input with high-DPI canvas scaling
• Configurable dimensions, output format, quality, and stroke properties
• Shared Form Flow screen and action components
• Default, compact, and immersive presentation variants
• Canonical signature result field

Installation

composer require 3neti/form-handler-signature
php artisan signature-handler:install --no-interaction

Usage

[
    'handler' => 'signature',
    'config' => [
        'width' => 600,
        'height' => 256,
        'quality' => 0.85,
        'format' => 'image/png',
        'line_width' => 2,
        'line_color' => '#000000',
        'line_cap' => 'round',
        'line_join' => 'round',
        'ui_variant' => 'compact',
    ],
]

Successful capture returns signature, timestamp, width, height, and format. The signature value is a data URL. Hosts should define retention, encryption, access-control, and redaction rules before persisting or logging signature artifacts.

Requirements

• PHP 8.2 or newer
• Laravel 12 or 13
• Form Flow 1.8 or newer
• Inertia Laravel 2 or 3
