Write Byte array into PDF file by java program

Hi,

I am facing problem whil writing byte data into PDF file.

Requirement:- I am reading Byte array from text file and then I want to create pdf file and write the bytes data on same file. The PDF file is created but no data is stored inside file.

So, could you please help me how can I solve the problem?

I am attaching my code and text file please check it.

Regards,

RSY

Hi Subramanum,

Thanks for your inquiry. I have not found the code and text file in attachment. It would be great if you please share your code and input file here for testing. I will investigate the issue on my side and provide you more information.

It seems that your query is not related to Aspose.Words. You can not write date into Pdf file by using Aspose.Words. Please share some more detail about your query. We will then provide you more information on this along with code.



Hi,

Thanks for quick response.

Apologies, for forgetting the attachment.

Please find the sample text file and code. I am using below jar files for running my code:-

1) Aspose.Words.jdk15.jar

2) aspose-pdf-2.7.0-jdk15.jar

3) aspose-pdf-kit-3.7.0.jar

4) iText-5.0.5.jar

Thanks & regards,

Hi Subramanum,

Thanks for sharing the detail. Your query is related to Aspose.Pdf. I am moving this forum thread to Aspose.Pdf forum. My colleagues from Aspose.Pdf team will reply you shortly.

Hi,

Thank you very much for quick response.

Hi Subramanum,

Further to my last post, I like to share with you that you can convert your Txt file into Pdf by using Aspose.Words. Following code example converts the Txt file into Pdf and also sets the orientation of the page to Landscape. Hope this helps you.

// Load in the document

Document doc = new Document(MyDir + "D111306260426.TXT");

for(Section secion : doc.getSections())

{

secion.getPageSetup().setOrientation(Orientation.LANDSCAPE);

}

//Save document to Pdf file format

doc.save(MyDir + "Out.pdf", SaveFormat.PDF);

Hi,

Thanks for quick solution.

Basically, I don't want to create Text file. I m getting byte array data from data base and then I want to write byte data into new PDF file.

So, could you please provide the solution?

Regards,

RSY

Hi Narayan,


Thanks for contacting support.

I would like to answer from Aspose.Pdf perspective. I have gone through the code snippet which you have shared and it seems to be based on iTextPdf API. However after going through your requirement description, my understanding is that you need to read the contents from D111306260426.TXT into Byte Array and then trying to create the PDF file based on contents in ByteArray.

I would like to share that Aspose.Pdf for .NET also supports the feature to read the contents from TXT file and save the output in PDF format. Instead of using ByteArray, you can simply load the file contents into TextReader object and pass this information to Text object of Aspose.Pdf.Generator namespace. Please visit the following link for further information on How to Convert a text file to PDF.

In case I have not properly understood your requirement or you have any further query, please feel free to contact.

Hi Narayan,

Thanks for your inquiry.

Yes, you can convert byte array (txt file) into Pdf file by using Aspose.Words. Please use the following code snippet to achieve your requirements. Hope this helps you. Please let us know if you have any more queries.

byte[] bytes = FileToArrayOfBytes();

// Load in the document

Document doc = new Document(new ByteArrayInputStream(bytes));

for(Section secion : doc.getSections())

{

secion.getPageSetup().setOrientation(Orientation.LANDSCAPE);

}

//Save document to Pdf file format

doc.save(MyDir + "Out.pdf", SaveFormat.PDF);

public static byte[] FileToArrayOfBytes()

{

FileInputStream fileInputStream = null;

File file = new File(MyDir + "D111306260426.TXT");

byte[] bFile = new byte[(int) file.length()];

try {

//convert file into array of bytes

fileInputStream = new FileInputStream(file);

fileInputStream.read(bFile);

fileInputStream.close();

}catch(Exception e){

e.printStackTrace();

}

return bFile;

}

So, could you please privide any solution. And also tell me any possibilities working same thing in 10.1.0.0 version because in production we are using same version of jar file.

Please find the attached code and text file for your reference.

Hi Narayan,

Thanks for your inquiry.

I have tested the scenario and have not found the shared issue while using latest version of Aspose.Words for Java. I would suggest you please upgrade to the latest version (v13.9.0) from here and let us know how it goes on your side. Hope this helps you. I have attached the output Pdf file with this post for your kind reference.
