2a8712e4fa Aggiunte informazioni versione e titolo dinamico
Sono state aggiunte informazioni sulla versione e sul prodotto
nel file `Ganimede.csproj`, inclusi dettagli come `Version`,
`Product`, `Description`, `Company` e altre proprietà.

Nel file `MainWindow.xaml.cs`, è stato aggiunto l'uso dello
spazio dei nomi `System.Reflection` e modificato il costruttore
di `MainWindow` per impostare dinamicamente il titolo della
finestra principale con la versione dell'applicazione.

---
## 🎯 Le Tre Modalità di Estrazione
Ganimede può estrarre immagini in tre modi diversi. Puoi scegliere quale usare nelle **Impostazioni**.
### 1⃣ **Modalità Completa** (Predefinita)
**Cosa fa:** Estrae **tutte** le immagini dal video, una per ogni fotogramma.
**Quando usarla:**
- Vuoi analizzare il video fotogramma per fotogramma
- Stai creando un'animazione
- Hai bisogno di tante immagini per un progetto
**Esempio:** Un video di 10 secondi a 30 fps = 300 immagini
**Pro:** Ottieni ogni singolo fotogramma
**Contro:** Crea tanti file (può richiedere molto spazio disco)
---
### 2⃣ **Modalità Singola Immagine**
**Cosa fa:** Estrae **1 sola** immagine dal centro del video.
**Quando usarla:**
- Vuoi solo un'anteprima o una copertina del video
- Hai bisogno di velocità (1 secondo per video)
- Vuoi risparmiare spazio su disco
**Esempio:** Un video di 10 secondi → 1 immagine dall'istante 5 secondi
**Pro:** Velocissimo, occupa poco spazio
**Contro:** Solo un'immagine per video
---
### 3⃣ **Modalità Automatica** (Intelligente)
**Cosa fa:** Ganimede **analizza** il video e **decide** automaticamente:
- Video molto breve (≤ 2 secondi) → Estrae 1 sola immagine
- Video breve ma statico (3-45 sec, poco movimento) → Estrae 1 sola immagine
- Altri video → Estrazione completa
**Quando usarla:**
- Hai una cartella con video di tipi diversi (corti e lunghi)
- Vuoi che Ganimede scelga il metodo migliore automaticamente
- Non sei sicuro quale modalità usare
**Esempio:**
- Video corto di 1 secondo → 1 immagine
- Video lungo di 5 minuti → tutte le immagini
**Pro:** Intelligente, ottimizza spazio e tempo automaticamente
**Contro:** Non hai controllo totale sulla scelta
---
**Come Cambiare Modalità:**
1. Clicca ⚙️ **"Impostazioni"** in alto
2. Vai alla sezione **"Impostazioni di Elaborazione"**
3. Cambia **"Modalità di Estrazione Predefinita"**
4. Clicca **"Salva"**
---
## ⚙️ Impostazioni (Personalizza Come Vuoi)
### Aprire le Impostazioni
Clicca il pulsante ⚙️ **"Impostazioni"** nella barra in alto.
---
### **Sezione: Output**
#### 📁 Crea sottocartella per ogni video
- **Cosa fa:** Se attivo, crea una cartella separata per ogni video
- **Esempio:**
-**Attivo:** `Output\vacanze\immagine_001.png`
-**Disattivo:** `Output\immagine_001.png` (tutti i video nella stessa cartella)
- **Consiglio:** Lascia attivo per evitare confusione
#### 📂 Cartella Output Predefinita
- **Cosa fa:** La cartella dove salvare tutte le immagini estratte
- **Come cambiarla:** Clicca **"Sfoglia"** e scegli una nuova cartella
- **Consiglio:** Usa una cartella facile da ricordare, come `Documenti\ImmaginiVideo`
---
### **Sezione: Impostazioni di Elaborazione**
#### 📐 Dimensione Immagini
Scegli quanto grandi devono essere le immagini estratte:
| Opzione | Risoluzione | Quando Usarla | Dimensione File |
|---------|-------------|---------------|-----------------|
| **Originale** | Come il video | Massima qualità | Grande (~1 MB) |
| **1920x1080** | Full HD | Video alta qualità | Media (~800 KB) |
| **1280x720** | HD | Uso normale | Piccola (~400 KB) |
| **640x360** | SD | Anteprime web | Molto piccola (~150 KB) |
| **320x180** | Miniatura | Icone/thumbnail | Mini (~56 KB) |
**Consiglio:** Per la maggior parte degli usi, **1280x720** è perfetto (qualità buona, file non troppo grandi).
---
#### 🔄 Comportamento Sovrascrittura
Cosa succede se le immagini esistono già nella cartella:
- **Chiedi** (predefinito): Ti chiede ogni volta cosa fare
- **Salta**: Non rielabora, salta le immagini già esistenti (utile per riprendere lavori interrotti)
- **Sovrascrivi**: Cancella e ricrea tutto (usa se vuoi rigenerare tutto)
**Consiglio:** Usa **"Chiedi"** la prima volta, poi **"Salta"** per risparmiare tempo.
---
#### 🎯 Modalità di Estrazione
Scegli la modalità predefinita (vedi sezione [Le Tre Modalità](#-le-tre-modalità-di-estrazione)):
- **Completa**: Tutte le immagini
- **Singola Immagine**: Solo 1 immagine
- **Automatica**: Ganimede decide (raccomandato se non sei sicuro)
---
#### 📂 Singolo Frame: Salvataggio
- **Cosa fa:** Quando usi "Singola Immagine", puoi decidere se creare comunque una sottocartella
-**Attivo:** Crea `Output\video\video_000001.png`
-**Disattivo:** Crea `Output\video_000001.png` (direttamente nella cartella principale)
**Consiglio:** Lascia disattivo per avere tutte le immagini singole in un unico posto.
---
### **Sezione: Naming File**
#### 🏷️ Come Chiamare i File
Ganimede può chiamare le immagini in modi diversi. Scegli quello che preferisci:
**1. VideoNameProgressive** (Predefinito)
```
vacanze_000001.png
vacanze_000002.png
vacanze_000003.png
```
**Usa questo se:** Vuoi file ordinati numericamente con il nome del video
**2. FrameProgressive**
```
frame_000001.png
frame_000002.png
frame_000003.png
```
**Usa questo se:** Non ti interessa il nome del video, vuoi solo numerazione
**3. VideoNameTimestamp**
```
vacanze_000000ms.png
vacanze_033ms.png
vacanze_067ms.png
```
**Usa questo se:** Vuoi sapere a che secondo del video corrisponde l'immagine
**4. CustomProgressive**
```
mio_prefisso_000001.png
mio_prefisso_000002.png
mio_prefisso_000003.png
```
**Usa questo se:** Vuoi dare un nome personalizzato ai file
**Come personalizzare:** Scrivi il tuo prefisso nel campo **"Prefisso Custom"** (es. `foto_vacanze`)
**5. TimestampOnly**
```
00h00m00s000ms.png
00h00m00s033ms.png
00h00m01s500ms.png
```
**Usa questo se:** Vuoi i nomi basati solo sul tempo
**6. VideoNameFrameProgressive**
```
vacanze_frame_000001.png
vacanze_frame_000002.png
vacanze_frame_000003.png
```
**Usa questo se:** Vuoi il massimo della chiarezza nei nomi

---
## 🔧 Risoluzione Problemi
### ❌ "L'applicazione non si avvia"
**Possibili cause:**
- .NET 8 non installato
- File corrotti
**Soluzione:**
1. Verifica .NET 8:
- Apri Prompt dei comandi
- Scrivi `dotnet --version`
- Se non vedi un numero, installa .NET 8 (vedi [Installazione](#-installazione-5-minuti))
2. Scarica di nuovo Ganimede ed estrai in una nuova cartella
3. Riavvia il computer
---
### ⏱️ "L'estrazione è molto lenta"
**Possibili cause:**
- Video in altissima risoluzione (4K)
- Dimensione immagini troppo grande
- Computer lento
**Soluzione:**
1. Usa dimensione **640x360** o **1280x720** invece di "Originale"
2. Salva le immagini su un disco veloce (SSD) se possibile
3. Elabora pochi video alla volta invece di 50 insieme
---
### 🖼️ "Le immagini sono nere o rovinate"
**Possibili cause:**
- Video corrotto
- Codec video non supportato
**Soluzione:**
1. Prova ad aprire il video con VLC o Windows Media Player
2. Se il video non si apre correttamente, è probabilmente corrotto
3. Se il video funziona ma Ganimede no, prova a convertirlo in MP4 con [HandBrake](https://handbrake.fr/) (gratuito)
---
### 📁 "Errore: Accesso negato"
**Possibili cause:**
- La cartella output è protetta (es. `C:\Programmi`)
- Un altro programma ha aperto i file
**Soluzione:**
1. Cambia cartella output in `Documenti` o `Desktop`
2. Chiudi programmi di visualizzazione immagini
3. Se necessario, esegui Ganimede come amministratore:
- Click destro su `Ganimede.exe`
- **"Esegui come amministratore"**
---
### 🖼️ "Non vedo l'anteprima delle immagini"
**Causa:** Pannello anteprima mostra solo le ultime 60 immagini.
**Soluzione:**
- Aspetta che un video finisca di elaborare
- Le anteprime appariranno automaticamente nella colonna destra
- Se la colonna è vuota, verifica che ci siano effettivamente file PNG nella cartella output
---
## 🎓 Suggerimenti per Principianti
### ✅ Cosa Fare Prima di Iniziare
1. **Crea una cartella dedicata** per le immagini estratte (es. `Documenti\ImmaginiDaVideo`)
2. **Prova con 1 video corto** prima di elaborare 100 video
3. **Usa la modalità Automatica** se non sei sicuro
4. **Controlla lo spazio disco** disponibile (1 minuto di video Full HD → ~1000 immagini → ~1 GB)
### ❌ Cosa Evitare
- ❌ Non usare cartelle di sistema come `C:\Windows` o `C:\Programmi`
- ❌ Non elaborare 100 video Full HD se hai poco spazio disco (controlla prima!)
- ❌ Non chiudere Ganimede durante l'elaborazione (usa "Ferma" se vuoi interrompere)
### 💡 Trucchi Utili
- 💡 **Seleziona più video** (Ctrl+Click o Shift+Click) per configurarli insieme
- 💡 **Riprendi lavori interrotti** impostando Sovrascrittura su "Salta"
- 💡 **Organizza per progetto** usando sottocartelle diverse (es. `Output\Vacanze`, `Output\Lavoro`)
---
