Save on memory --> encode base64 PDF (java)

[riturra84]

Hi!

I´m building a function to recive base64 PDF, process and return base64 again:

This part of code is wirking

Code: Select all

//Decode base64
byte[] decoded = java.util.Base64.getDecoder().decode(base64_in);   
//Load on PdfDocument   
pdf.loadFromBytes(decoded);   
//Remove embedded javascript
pdf.removeDocumentJavaScript();
//Save to file to test, but I don't want to save on filesystem
pdf.saveToFile("output.pdf", FileFormat.PDF);
//Here I need to save on memory and encode to base64 again


How can I do this?

Regards.

Hello,

Thanks for your inquiry.

Please refer to the modified code below.

Code: Select all

        //Decode base64
        byte[] decoded = java.util.Base64.getDecoder().decode(base64_in);
        //Load on PdfDocument
        pdf.loadFromBytes(s);
        //Remove embedded javascript
        pdf.removeDocumentJavaScript();
        //Save to file to test, but I don't want to save on filesystem
        pdf.saveToFile("output.pdf", FileFormat.PDF);
        //Here I need to save on memory and encode to base64 again

        //Write the pdf to stream
        ByteArrayOutputStream stream=new ByteArrayOutputStream();
        pdf.saveToStream(stream);
        //Convert the stream to byte array and encode
        byte[] encoded=java.util.Base64.getEncoder().encode(stream.toByteArray());
        //Close the stream
        stream.close();
