Image is not getting inserted in a existing PDF #575
Description
I have an existing PDF, and I want to insert an image at a specific location. There are no errors when using the PDF or executing the code, but the image is not appearing. However, it works with other PDF files.
private String FILE_NAME ="my.pdf";
private int FILE_ID = R.raw.sam;
private String FILE_NAME1 ="my1.pdf";
private String IMAGE_FILE_NAME ="myImage.png";
public void addImage(File pFile) {
try {
if (!pFile.exists()) {
pFile.createNewFile();
}
PDDocument vDocument = PDDocument.load(pFile);
//get the number of pages
PDPage vPage = vDocument.getPage(0);
PDPageContentStream vContentStream;
File vFile = new File(getCacheDir(), IMAGE_FILE_NAME);
File vFileNew = new File(getCacheDir(), FILE_NAME1);
copyToCache(vFile, R.raw.sample1);
// Define a content stream for adding to the PDF
vContentStream = new PDPageContentStream(vDocument, vPage, PDPageContentStream.AppendMode.APPEND, true, true);
// Draw the falcon base image
PDImageXObject vImage = PDImageXObject.createFromFileByContent(vFile,vDocument);
/*
Bitmap vBitMap = BitmapFactory.decodeResource(getResources(), R.drawable.sample1);
ByteArrayOutputStream vBAOS = new ByteArrayOutputStream();
vBitMap.compress(Bitmap.CompressFormat.JPEG, 100, vBAOS);
InputStream vInStream = new ByteArrayInputStream(vBAOS.toByteArray());
PDImageXObject vImage = JPEGFactory.createFromStream(vDocument, vInStream);
*/
vContentStream.drawImage(vImage, 50, 600,100,100);
vContentStream.saveGraphicsState();
vContentStream.restoreGraphicsState();
vContentStream.close();
// Save the final pdf document to a file
vDocument.save(vFileNew);
vDocument.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private void copyToCache(File pFile, @RawRes int pResourceID) throws IOException {
//Get input stream object to read the pdf
InputStream vInput = getResources().openRawResource(pResourceID);
FileOutputStream vOutput = new FileOutputStream(pFile);
byte[] vBuffer = new byte[1024];
int vSize;
// Copy the entire contents of the file
while ((vSize = vInput.read(vBuffer)) != -1) {
vOutput.write(vBuffer, 0, vSize);
}
//Close the buffer
vInput.close();
vOutput.close();
}
Expected behavior
The image should be inserted at the correct location.
Actual behavior
No exception is occurring, but the image is not appearing.
