In questo argomento esploreremo come convertire EPS in TIFF utilizzando C++. Osserverai come caricare il file EPS di input e convertirlo in immagine in C++ usando semplici chiamate API.
Passaggi per convertire EPS in TIFF usando C++
- Installa Aspose.Page for C++ da NuGet Package Manager Tool
- Aggiungi riferimento allo spazio dei nomi Aspose::Page
- Specificare l’output ImageFormat e inizializzare un flusso di input
- Carica il file EPS di input utilizzando l’oggetto della classe PsDocument
- Imposta le proprietà di ImageSaveOptions e salva il file TIFF di output
Puoi esportare EPS in TIFF usando C++ usando semplici chiamate API con poche righe di codice. Devi semplicemente caricare il file EPS di input e impostare proprietà diverse in base alle tue esigenze, quindi convertire il file con PsDocument class utilizzando C++.
