He dibujado el siguiente diagrama de flujo bajo la clase de documento "independiente", pero el documento original en el que se va a fusionar es de clase de documento "artículo". Entonces, cuando pego el código en mi documento principal, el diagrama de flujo se reduce y se vuelve demasiado pequeño en comparación con el diagrama original. Quiero que el diagrama de flujo ocupe una página completa de tamaño A4.

Para convertir standalonela clase de documento a articlesolo necesita reemplazar standalonecon article. Esa imagen se centrará en la página y la encerrará en \begin{center}... \end{center}o la pondrá en figureun entorno flotante:
