技术小贴士 – 转换文本文件为PDF

客户经常询问我们如何将他们的文本文件转换为PDF。我们也经常问到是否可以快速提供能完成该任务的代码并保存至文档当中。本着为用户考虑的原则，我们提供一个使用Aspose.Pdf可以简单有效地将文本文件转换为PDF的简单示例。


[C#]


System.IO.TextReader tr = new StreamReader("test.txt");

//Instantiate Pdf pbject by calling its empty constructor

Aspose.Pdf.Pdf pdf1 = new Aspose.Pdf.Pdf();

//Create a new section in the Pdf object

Aspose.Pdf.Section sec1 = pdf1.Sections.Add();

//Create a new text paragraph and pass the text to its constructor as argument

Aspose.Pdf.Text t2 = new Aspose.Pdf.Text(tr.ReadToEnd());

sec1.Paragraphs.Add(t2);

pdf1.Save("test.Pdf");


[VB.NET]


Dim tr As System.IO.TextReader = New StreamReader("test.txt")

‘Instantiate Pdf pbject by calling its empty constructor

Dim pdf1 As Aspose.Pdf.Pdf = New Aspose.Pdf.Pdf()

‘Create a new section in the Pdf object

Dim sec1 As Aspose.Pdf.Section = pdf1.Sections.Add()

‘Create a new text paragraph and pass the text to its constructor as argument

Dim t2 As Aspose.Pdf.Text = New Aspose.Pdf.Text(tr.ReadToEnd())

sec1.Paragraphs.Add(t2)

pdf1.Save("test.Pdf")


[Java]


try{

   StringBuffer sb = new StringBuffer(1024);

   BufferedReader reader = new BufferedReader(new FileReader("test.txt"));
                                   
   char[] chars = new char[1024];

   int numRead = 0;

   while( (numRead = reader.read(chars)) > -1){

      sb.append(String.valueOf(chars));     

   }

   reader.close();

   //Instantiate Pdf pbject by calling its empty constructor

   Pdf pdf1 = new Pdf();

   //Create a new section in the Pdf object

   Section sec1 = pdf1.getSections().add();

   //Create a new text paragraph and pass the text to its constructor as argument

   Text text1 = new Text(sec1,sb.toString());

   sec1.getParagraphs().add(text1);
                                   
   pdf1.save(new FileOutputStream(new File("test.pdf")));

}catch(java.io.IOException ioe){

   System.out.println(ioe.getMessage());

}catch(AsposeBaseException e){

   System.out.println(e.getMessage());

}
