That's a very old way. See the example read_tiffs.java at itextpdf.sf.net.

Hello Paulo,

 

here's the code:

 

 public byte[] convert(byte[] src) throws FSMException {
  Document document = new Document(PageSize.A4);
  float usableWidth = document.right()-document.left();
  float usableHeight = document.top()-document.bottom();
  
  ByteArrayOutputStream bout = new ByteArrayOutputStream();
 
  byte[] result = null;

 

  try {     
      PdfWriter writer = PdfWriter.getInstance(document,bout);
      writer.setEncryption(PdfWriter.STRENGTH40BITS, null, null, PdfWriter.AllowPrinting | PdfWriter.AllowScreenReaders | PdfWriter.AllowCopy);
      ByteArraySeekableStream in = new ByteArraySeekableStream(src);
       
      TIFFDirectory dir = new TIFFDirectory(in,0);
      long IFDOffset = dir.getIFDOffset();
      document.open();
      PdfContentByte cb = writer.getDirectContent();
       
      while(IFDOffset != 0L) {
       dir = new TIFFDirectory(in, IFDOffset, 0);
          IFDOffset = dir.getNextIFDOffset();
          long h = dir.getFieldAsLong(TIFFImageDecoder.TIFF_IMAGE_LENGTH);
          long w = dir.getFieldAsLong(TIFFImageDecoder.TIFF_IMAGE_WIDTH);
          long offset = dir.getFieldAsLong(TIFFImageDecoder.TIFF_STRIP_OFFSETS);
          long size = dir.getFieldAsLong(TIFFImageDecoder.TIFF_STRIP_BYTE_COUNTS);
          boolean reverse = false;
          if (dir.isTagPresent(TIFFImageDecoder.TIFF_FILL_ORDER)) {
              reverse = (dir.getFieldAsLong(TIFFImageDecoder.TIFF_FILL_ORDER) == 2L);
          }
          
          int compression = (int)dir.getFieldAsLong(TIFFImageDecoder.TIFF_COMPRESSION);
          
          switch (compression) {
              case TIFFImage.COMP_FAX_G3_1D:
                   compression = Image.CCITTG3_1D;
                   break;
              case TIFFImage.COMP_FAX_G3_2D:
                   compression = Image.CCITTG3_1D;
                   if (dir.isTagPresent(TIFFImageDecoder.TIFF_T4_OPTIONS)) {
                       if (((int)dir.getFieldAsLong(TIFFImageDecoder.TIFF_T4_OPTIONS) & 1) != 0)  {
                           compression = Image.CCITTG3_2D;
                       }
                   }
                   break;
              case TIFFImage.COMP_FAX_G4_2D:
                   compression = Image.CCITTG4;
                   break;
              default:
                   throw new UnsupportedOperationException("Compression type " + compression + " not supported");
          }
          byte im[] = new byte[(int)size];
          in.seek(offset);
          in.readFully(im);
          // IMAGE FROM RAWDATA ...
          Image img = Image.getInstance((int)w, (int)h, reverse, compression, 0, im);
          img.scaleToFit(usableWidth,usableHeight);
          img.setAbsolutePosition(document.left(), document.bottom());
          cb.addImage(img);
          document.newPage();
      }
      document.close();
      
      result = bout.toByteArray();
  
      bout.close();
  } catch (Exception e) {
   throw new FSMException(new ErrorMessageVB(FSMKeys.SEVERITY_ERROR,FSMKeys.ERROR_GLOBAL_CONVERTER, e.getMessage()));
  }
  
     return result;
 }
}

 

 

Best regards,

Stefan.

It should work with Acrobat 4 and above. What code are you using to read the tiff?

Hello,

My client is getting reports from customers who have the commercial Acrobat software (as opposed to the free Acrobat Reader) installed, complaining that they cannot view or print the PDF documents that the application serves using iText 1.02b. The PDF documents consist just of one large TIFF image.

Is anything known about compatibility issues in this respect? In particular, what is the oldest Acrobat version that should be able to process a PDF generated by iText 1.02b, containing a TIFF image?

Best regards,
Stefan.
