Setting image using byte in pdf file

Aspose.PDF Product Family

Hi,

I am trying to set image in PDF file. Here is my code

byte[] signatureData = userPhoto.getContents();
BinaryFileStream bufferIn = new BinaryFileStream ();
bufferIn.read(signatureData, 0, signatureData.length);

Image img1 =(Image)pdfSection.getObjectByID("signatureImage");
img1.getImageInfo().setImageStream(bufferIn);
bufferIn.close();

MemStream ms = new MemStream();
pdfDoc.save(ms);

XML Template

I am getting following exception when saving to memStream.
java.io.IOException: Stream closed
at java.io.BufferedInputStream.getInIfOpen(BufferedInputStream.java:134)

How can I set image using byte[].

Thanks

Hi Mamatha,

Thanks for your patience.

I have investigated this scenario and as per my understanding, the problem might be occurring because you have called bufferIn.close(); method before saving the PDF document. However you may consider using the following code snippet to load the XML file, read the Image file and place it inside PDF document.

[Java]

// instantiate Pdf object
Pdf pdf1 = new Pdf();

// bind the source XML
pdf1.bindXML("d:/pdftest/Template_new (1).xml", null);

// get Section object already specified in XML file
Section sec1 = pdf1.getSections().getSection("Section1");

// get the Image Object as specified in XML file
aspose.pdf.Image image3 = (Image)sec1.getObjectByID("signatureImage");

// Read the source Image file
BinaryFileStream binarydata = new BinaryFileStream("d:/pdftest/bird_67.png");

// set contents of BinaryFileStream to Image object
image3.getImageInfo().setImageStream(binarydata);

// specify the type of image file
image3.getImageInfo().setImageFileType(ImageFileType.Png);

// save PDF document
pdf1.save("d:/pdftest/StreamImage-Test.pdf");

// close the Binary Stream
binarydata.close();

[XML]

<?xml version="1.0" encoding="utf-8"?>
<Pdf xmlns="Aspose.Pdf">
  <Section ID="Section1">
    <Image ID="signatureImage" File=""></Image>
  </Section>
</Pdf>

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

Hi,

I tried like this. But it did not work.

byte[] signatureData;
BinaryFileStream binaryFileStream = new BinaryFileStream (signatureData);

Image img1 =(Image)pdfSection.getObjectByID("signatureImage");

img1.getImageInfo().setImageStream(binaryFileStream);
img1.getImageInfo().setImageFileType(ImageFileType.Jpeg);

//writing pdf document to MemStream
MemStream ms = new MemStream();
pdfDoc.save(ms); //at this place system is hanging

Thanks

Hi Mamatha,

Thanks for your patience.

I have again tested the scenario where I have tried loading the Image file into BufferImage object, then created a Byte array, instantiated the BinaryFileStream object with Byte array contents and then I have passed these contents to setImageStream(...) and as per my observations, I am getting an Exception while saving the PDF document.

For the sake of correction, I have logged it in our issue tracking system as PDFJAVA-33153. We will investigate this issue in details and will keep you updated on the status of a correction. I have used the following code snippet to test the scenario.

We apologize for your inconvenience.

[Java]

// load the source image file
BufferedImage img = ImageIO.read(new File("d:/pdftest/Question.png"));

// create byte array output stream
ByteArrayOutputStream bas = new ByteArrayOutputStream();

// write image to byte array output stream
ImageIO.write(img, "pnm", bas);

// instantiate byte array with image contents
byte[] data = bas.toByteArray();

// instantiate Pdf object
Pdf pdf1 = new Pdf();

// bind the source XML
pdf1.bindXML("d:/pdftest/Template_new(1).xml", null);

// get Section object already specified in XML file
Section sec1 = pdf1.getSections().getSection("Section1");

// get the Image Object as specified in XML file
aspose.pdf.Image image3 = (Image)sec1.getObjectByID("signatureImage");

// Read the source Image file
BinaryFileStream binarydata = new BinaryFileStream(data);

// set contents of BinaryFileStream to Image object
image3.getImageInfo().setImageStream(binarydata);

// specify the type of image file
image3.getImageInfo().setImageFileType(ImageFileType.Png);

// save PDF document
pdf1.save("d:/pdftest/StreamImage-Test.pdf");

// close the Binary Stream
binarydata.close();
