Adicionar Carimbo de P\u00e1gina em PDF em Todas as P\u00e1ginas de um Arquivo PDF<\/h2>\n

A classe PdfFileStamp<\/a> permite adicionar um carimbo de p\u00e1gina em PDF em todas as p\u00e1ginas de um arquivo PDF.\nIn order to add PDF page stamp, you first need to create objects of PdfFileStamp<\/a> e Stamp<\/a> classes. Voc\u00ea tamb\u00e9m precisa criar o carimbo da p\u00e1gina PDF usando o m\u00e9todo PdfFileStamp<\/a> da classe Stamp<\/a>. Voc\u00ea pode definir outros atributos como origem, rota\u00e7\u00e3o, fundo etc. usando o objeto Stamp<\/a> tamb\u00e9m. Em seguida, voc\u00ea pode adicionar o carimbo no arquivo PDF usando o m\u00e9todo addStamp<\/a> da classe PdfFileStamp<\/a>. Finalmente, salve o arquivo PDF de sa\u00edda usando o m\u00e9todo close<\/a> da classe PdfFileStamp<\/a>. O trecho de c\u00f3digo a seguir mostra como adicionar um carimbo de p\u00e1gina PDF em todas as p\u00e1ginas de um arquivo PDF.<\/p>\n

Adicionar Carimbo de P\u00e1gina em PDF em P\u00e1ginas Espec\u00edficas de um Arquivo PDF<\/h2>\n
A classe PdfFileStamp<\/a> permite adicionar um carimbo de p\u00e1gina em PDF em p\u00e1ginas espec\u00edficas de um arquivo PDF.\nPara adicionar uma marca de p\u00e1gina em PDF, voc\u00ea precisa primeiro criar objetos das classes PdfFileStamp<\/a> e Stamp<\/a>. Voc\u00ea tamb\u00e9m precisa criar o carimbo de p\u00e1gina em PDF usando o m\u00e9todo bindPdf<\/a> da classe Stamp<\/a>. Voc\u00ea pode definir outros atributos como origem, rota\u00e7\u00e3o, fundo etc. usando o objeto Stamp<\/a> tamb\u00e9m. Como voc\u00ea deseja adicionar um carimbo de p\u00e1gina em PDF em p\u00e1ginas espec\u00edficas do arquivo PDF, voc\u00ea tamb\u00e9m precisa definir a propriedade Pages<\/a> da classe Stamp<\/a>. Esta propriedade requer um array de inteiros contendo os n\u00fameros das p\u00e1ginas nas quais voc\u00ea deseja adicionar o carimbo. Em seguida, voc\u00ea pode adicionar o carimbo no arquivo PDF usando o m\u00e9todo addStamp<\/a> da classe PdfFileStamp<\/a>. Finalmente, salve o arquivo PDF de sa\u00edda usando o m\u00e9todo close<\/a> da classe PdfFileStamp<\/a>.

Adicionar N\u00famero de P\u00e1gina em um Arquivo PDF (facades)<\/h2>\n
A classe PdfFileStamp<\/a> permite que voc\u00ea adicione n\u00fameros de p\u00e1gina em um arquivo PDF.\nPara adicionar n\u00fameros de p\u00e1gina, voc\u00ea primeiro precisa criar um objeto da classe PdfFileStamp<\/a>. Se voc\u00ea quiser mostrar o n\u00famero da p\u00e1gina como “P\u00e1gina X de N”, sendo X o n\u00famero da p\u00e1gina atual e N o n\u00famero total de p\u00e1ginas no arquivo PDF, ent\u00e3o voc\u00ea primeiro precisa obter a contagem de p\u00e1ginas usando a propriedade getNumberOfpages da classe PdfFileInfo<\/a>. Para obter o n\u00famero da p\u00e1gina atual, voc\u00ea pode usar o sinal #<\/strong> em seu texto onde quiser. Voc\u00ea pode formatar o texto do n\u00famero da p\u00e1gina usando a classe FormattedText<\/a>. Se voc\u00ea quiser come\u00e7ar a numera\u00e7\u00e3o das p\u00e1ginas a partir de um n\u00famero espec\u00edfico, ent\u00e3o voc\u00ea pode definir a propriedade setStartingNumber. Quando estiver pronto para adicionar o n\u00famero da p\u00e1gina no arquivo, voc\u00ea precisar\u00e1 chamar o m\u00e9todo addPageNumber da classe PdfFileStamp<\/a>. Finalmente, salve o arquivo PDF de sa\u00edda usando o m\u00e9todo Save da classe PdfFileStamp<\/a>.<\/p>\n

Estilo de Numera\u00e7\u00e3o Personalizado<\/h3>\n
A classe PdfFileStamp<\/a> oferece a funcionalidade de adicionar informa\u00e7\u00f5es de N\u00famero de P\u00e1gina como objeto de carimbo dentro de um documento PDF. Antes deste lan\u00e7amento, a classe s\u00f3 suportava 1,2,3,4 como estilo de numera\u00e7\u00e3o de p\u00e1ginas. No entanto, houve uma exig\u00eancia de alguns clientes para usar um estilo de numera\u00e7\u00e3o personalizado ao colocar o carimbo de n\u00famero de p\u00e1gina dentro do documento PDF. Para atender a essa necessidade, a propriedade NumberingStyle<\/a> foi introduzida, a qual aceita os valores da enumera\u00e7\u00e3o NumberingStyle<\/a>. Abaixo est\u00e3o especificados os valores oferecidos nesta enumera\u00e7\u00e3o.<\/p>\n
