Agregar Encabezados y Pies HTML

Configure las opciones de renderizado para incluir un encabezado y pie de página HTML al renderizar un documento PDF con IronPDF, una biblioteca de Iron Software que permite una avanzada generación y manipulación de PDF.

Defina el contenido del encabezado con una línea divisoria, un fragmento HTML y especifique la altura máxima del encabezado utilizando las herramientas flexibles de renderizado de PDF de IronPDF. De manera similar, defina el contenido del pie de página utilizando la propiedad htmlHeader proporcionada por IronPDF.

Tenga en cuenta que la altura del encabezado y el pie de página no se detecta automáticamente, lo que significa que pueden superponerse con el contenido HTML principal. Personalice los márgenes para asegurar que el encabezado y el pie de página estén colocados adecuadamente.

Para más detalles sobre cómo implementar encabezados, pies de página o para explorar otras características, visite el Sitio Web Oficial de IronPDF.
