A\u00f1adir Sello de P\u00e1gina PDF en Todas las P\u00e1ginas de un Archivo PDF<\/h2>\n

La clase PdfFileStamp<\/a> permite a\u00f1adir un sello de p\u00e1gina PDF en todas las p\u00e1ginas de un archivo PDF.\nIn order to add PDF page stamp, you first need to create objects of PdfFileStamp<\/a> y Stamp<\/a> clases. Necesita tambi\u00e9n crear el sello de p\u00e1gina PDF utilizando el m\u00e9todo PdfFileStamp<\/a> de la clase Stamp<\/a>. Puede establecer otros atributos como origen, rotaci\u00f3n, fondo, etc. utilizando tambi\u00e9n el objeto Stamp<\/a>. Luego puede agregar el sello en el archivo PDF utilizando el m\u00e9todo addStamp<\/a> de la clase PdfFileStamp<\/a>. Finalmente, guarde el archivo PDF de salida utilizando el m\u00e9todo close<\/a> de la clase PdfFileStamp<\/a>.

A\u00f1adir Sello de P\u00e1gina PDF en P\u00e1ginas Particulares de un Archivo PDF<\/h2>\n
La clase PdfFileStamp<\/a> permite a\u00f1adir un sello de p\u00e1gina PDF en p\u00e1ginas particulares de un archivo PDF.\nIn order to add PDF page stamp, you first need to create objects of PdfFileStamp<\/a> y Stamp<\/a> clases. Necesitas crear el sello de p\u00e1gina PDF usando el m\u00e9todo bindPdf<\/a> de la clase Stamp<\/a>. Puedes establecer otros atributos como origen, rotaci\u00f3n, fondo, etc. usando el objeto Stamp<\/a> tambi\u00e9n. Como desea agregar un sello de p\u00e1gina PDF en p\u00e1ginas particulares del archivo PDF, tambi\u00e9n necesita establecer la propiedad Pages<\/a> de la clase Stamp<\/a>. Esta propiedad requiere un arreglo de enteros que contenga los n\u00fameros de las p\u00e1ginas en las que desea agregar el sello. Luego puede agregar el sello en el archivo PDF usando el m\u00e9todo addStamp<\/a> de la clase PdfFileStamp<\/a>. Finalmente, guarde el archivo PDF de salida usando el m\u00e9todo close<\/a> de la clase PdfFileStamp<\/a>.

A\u00f1adir N\u00famero de P\u00e1gina en un Archivo PDF (facades)<\/h2>\n
La clase PdfFileStamp<\/a> te permite a\u00f1adir n\u00fameros de p\u00e1gina en un archivo PDF.\nPara agregar n\u00fameros de p\u00e1gina, primero necesitas crear un objeto de la clase PdfFileStamp<\/a>. Si deseas mostrar el n\u00famero de p\u00e1gina como “P\u00e1gina X de N” siendo X el n\u00famero de p\u00e1gina actual y N el n\u00famero total de p\u00e1ginas en el archivo PDF, primero necesitas obtener el conteo de p\u00e1ginas usando la propiedad getNumberOfpages de la clase PdfFileInfo<\/a>. Para obtener el n\u00famero de la p\u00e1gina actual, puedes usar el signo #<\/strong> en tu texto en cualquier lugar que desees. Puedes dar formato al texto del n\u00famero de p\u00e1gina usando la clase FormattedText<\/a>. Si deseas comenzar la numeraci\u00f3n de p\u00e1ginas desde un n\u00famero espec\u00edfico, puedes establecer la propiedad setStartingNumber. Una vez que est\u00e9s listo para agregar el n\u00famero de p\u00e1gina en el archivo, necesitas llamar al m\u00e9todo addPageNumber de la clase PdfFileStamp<\/a>. Finalmente, guarda el archivo PDF de salida usando el m\u00e9todo Save de la clase PdfFileStamp<\/a>.<\/p>\n

Estilo de Numeraci\u00f3n Personalizado<\/h3>\n
La clase PdfFileStamp<\/a> ofrece la funci\u00f3n de agregar informaci\u00f3n de n\u00famero de p\u00e1gina como objeto de sello dentro del documento PDF. Antes de esta versi\u00f3n, la clase solo soportaba 1,2,3,4 como estilo de numeraci\u00f3n de p\u00e1ginas. Sin embargo, ha habido una demanda de algunos clientes para usar un estilo de numeraci\u00f3n personalizado al colocar el sello de n\u00famero de p\u00e1gina dentro del documento PDF. Para cumplir con este requisito, se ha introducido la propiedad NumberingStyle<\/a>, que acepta los valores de la enumeraci\u00f3n NumberingStyle<\/a>. A continuaci\u00f3n se especifican los valores ofrecidos en esta enumeraci\u00f3n.<\/p>\n

La clase PdfFileStamp<\/a> te permite a\u00f1adir un sello de texto en p\u00e1ginas particulares de un archivo PDF.\nIn order to add text stamp, you first need to create objects of PdfFileStamp<\/a> y Stamp<\/a> clases. Necesitas crear el sello de texto utilizando el m\u00e9todo bindPdf<\/a> de la clase Stamp<\/a>. Puedes establecer otros atributos como origen, rotaci\u00f3n, fondo, etc. usando el objeto Stamp<\/a> tambi\u00e9n. Como deseas agregar una marca de texto en p\u00e1ginas espec\u00edficas del archivo PDF, tambi\u00e9n necesitas establecer la propiedad Pages<\/a> de la clase Stamp<\/a>. Esta propiedad requiere un arreglo de enteros que contenga los n\u00fameros de las p\u00e1ginas en las que deseas agregar la marca. Luego puedes agregar la marca en el archivo PDF usando el m\u00e9todo addStamp<\/a> de la clase PdfFileStamp<\/a>. Finalmente, guarda el archivo PDF de salida usando el m\u00e9todo close<\/a> de la clase PdfFileStamp<\/a>.
