Installazione

Puoi usare il nostro Setup assistito dall'AI per installare il plugin. Aggiungi le skill Capgo al tuo tool AI con il comando seguente:

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

Poi usa questo prompt:

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-document-scanner` plugin in my project.

Se preferisci il Setup manuale, installa il plugin eseguendo i comandi seguenti e segui le istruzioni specifiche per piattaforma qui sotto:

bun add @capgo/capacitor-document-scanner
bunx cap sync

Importa

import { DocumentScanner } from '@capgo/capacitor-document-scanner';

Avvio rapido

import { DocumentScanner, ResponseType } from '@capgo/capacitor-document-scanner';

const result = await DocumentScanner.scanDocument({
  maxNumDocuments: 1,
  responseType: ResponseType.ImageFilePath,
});

if (result.status === 'success' && result.scannedImages?.length) {
  await uploadReceipt(result.scannedImages[0]);
}

Esempio: pacchetto multi-pagina

const result = await DocumentScanner.scanDocument({
  maxNumDocuments: 12,
  letUserAdjustCrop: true,
  reviewCapturedDocument: true,
});

Gli scanner nativi supportano fino a 24 pagine per sessione.

Esempio: ottimizzazione cleanup Android

import { ScannerMode } from '@capgo/capacitor-document-scanner';

await DocumentScanner.scanDocument({
  scannerMode: ScannerMode.Full,
  brightness: 0.1,
  contrast: 1.2,
});

scannerMode e le opzioni di pulizia ML sono disponibili solo su Android. Vedi le opzioni del plugin in scanDocument per l'elenco completo.

Errori comuni

• Web: pianifica un fallback (file picker o foto manuale) poiché la scansione è solo nativa.
• User cancel: status e può essere cancel senza immagini; gestiscilo come qualsiasi altra chiusura.
• Tipo di output: scegli imageFilePath o base64 tramite responseType prima di configurare gli upload.

API Panoramica

scanDocument

Apre la fotocamera del dispositivo e avvia l'esperienza di scansione del documento.
