How can I convert a text file to a pdf?


How can I convert a text file to a pdf file ?

I am using Aspose 2.9.0

Hello Sriman,

Thanks for your interest in our products.

Please visit the following link for information on Converting text file to PDF.


I need to convert the attached text file to a PDF. I have written the following code but not able to convert it to pdf.

public static void convertTextFiles()throws Exception{

//.txt file

String inputFile = "C:\\ziptest\\Parent\\Child2\\AsposeDelegate.txt";

String data = readTextFileAsChars(new File(inputFile));


Pdf pdf1 = new Pdf();

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

Text text1 = new Text(sec1,data);



static public String readTextFileAsChars(File aFile) {

StringBuilder contents = new StringBuilder();

try {

BufferedReader input = new BufferedReader(new FileReader(aFile));

try {

char[] chars = new char[1024];

int numRead = 0;

while( (numRead = > -1){




finally {




catch (IOException ex){



return contents.toString();


But I am getting the following exception :

AsposeDelegate Error in main


at aspose.pdf.xml.Ack.a(SourceFile:2538)

at aspose.pdf.xml.Ack.a(SourceFile:2430)

at aspose.pdf.xml.Acm.a(SourceFile:494)

at aspose.pdf.xml.Acc.a(SourceFile:784)

at aspose.pdf.xml.Aar.a(SourceFile:97)

at aspose.pdf.xml.Aba.a(SourceFile:112)


at AsposeFileConverter.convertHugeTextFilesByFileReader(

at AsposeFileConverter.convertFile(

at AsposeDelegate.convertFile(

at AsposeDelegate.main(

Even I tried your other approach to convertHugeText file still getting the same Exception.

Code Snippet for Huge text file :

public static void convertHugeTextFilesByFileReader() throws Exception{

String inputFile = "C:\\ziptest\\Parent\\Child2\\AsposeDelegate.txt";

Pdf pdf1 = new Pdf();

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

FileInputStream fstream = new FileInputStream(inputFile);

DataInputStream in = new DataInputStream(fstream);

BufferedReader br = new BufferedReader(new InputStreamReader(in));

String strLine;

while ((strLine = br.readLine()) != null)


Text text1 = new Text(sec1,strLine);





But it works when the file line size is reduced to 25-30 lines.

Please help...

Is there maximum allowable size for a Section ?

Hello Sriman,

Thanks for your interest in our products.

I have tested the scenario and I am able to notice that NullPointerException is being generated when converting the source Text file (that you have shared) into PDF format. For the sake of correction, I have logged it in our issue tracking system as PDFJAVA-28698. We will investigate this issue in details and will keep you updated on the status of a correction.

I am not entirely certain why this issue is occurring. In fact there is no specific limitation regarding source document size.

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

We apologize for your inconvenience.
