Overview

Overview

HandwritingInput is multi-saas-kit's first Layer 2 Composite Plugin, assembled from 3 base plugins. It provides a single entry point for the canvas stroke input → provider recognition call → normalized result flow.

Dependencies (3 base plugins)

Plugin	Role	Layer
DigitalInk	Stroke standard + validation	L0 Foundation
BrushConfiguration	Canvas / brush rendering config	L0 Foundation
RecognitionBridge	Recognition API adapters	L1 Core

Core Component

HandwritingInputService

Single entry point process() encapsulating 5 steps:

1. StrokeData::fromArray($payload)        ← DigitalInk validation
2. (optional) Normalize round-trip        ← Coordinate cleanup
3. RecognizerInterface::recognize         ← RecognitionBridge
4. (optional) Normalize brush config      ← Brush meta attachment
5. (optional) Compute bounding box        ← Drawing area meta
→ HandwritingInputResult

HandwritingInputResult (DTO)

{
  ok, provider, elapsed_ms, candidates, message,
  canvas: { width, height },
  brush: { line_width, stroke_color, ... },       // when include_brush=true
  bounding_box: { min_x, max_x, width, ... }      // when include_bounding=true
}

Configuration

return [
    'enabled' => env('PLG_HANDWRITING_INPUT_ENABLED', true),
    'flow' => [
        'normalize_strokes' => false,
        'include_brush'     => true,
        'include_bounding'  => true,
    ],
];

Usage

$service = new HandwritingInputService(
    recognizer: $chain,
    strokeNormalizer: new StrokeNormalizer,
    brushNormalizer: BrushConfigNormalizer::fromConfig(config('brush-configuration')),
    flow: config('handwriting-input.flow'),
);

$result = $service->process(
    payload: ['ink' => [...], 'width' => 200, 'height' => 100],
    brushInput: ['line_width' => 8],
    options: ['language' => 'en', 'mode' => 'numeric'],
);

Scope

HandwritingInput only composes the input stack. It does not include domain scoring, learning evaluation, submission workflows, or UI screens. Recognition provider operations and billing belong to the configured provider project, and SaaS-specific business rules belong to the consumer side.
