long length = file.length();
bytes = new byte[(int) length];
int offset = 0;
int numRead = 0;
while (offset < bytes.length
&& (numRead = is.read(bytes, offset, bytes.length
- offset)) >= 0) {
offset += numRead;
}
ByteBuffer buffer = ByteBuffer.NEW(bytes);
String data = Base64.encodeToString(bytes, Base64.DEFAULT);
PDFFile pdf_file = new PDFFile(buffer);
PDFPage page = pdf_file.getPage(1);
RectF rect = new RectF(0, 0, (int) page.getBBox().width(),(int) page.getBBox().height());
Bitmap image = page.getImage((int) rect.width(),(int) rect.height(), rect);
imageView.setImageBitmap(image);
//FileOutputStream os = new FileOutputStream(Environment.getExternalStorageDirectory()+ "/pdfImage.jpg");
//image.compress(Bitmap.CompressFormat.JPEG, 80, os);
