Hi,
I have some problems with a tiff-compression. What I use is tiff2pdf converter.
For most
tiff’s (b&w FaxG4) everything’s working just fine. BUT with all colored tiff’s,
I get
IllegalArgumentException or RuntimeException (see bottom please). I can open
that tiff
with IrfanView, so the file (buffer) is not corrupted.
What am I doing wrong? Thanx in advance

p.s.: IrfanView says (“Compression: Old JPEG (in TIFF)”?!?
public byte[] tiff2pdf(byte[] tifBuffer)
{
byte[] pdfBuffer = null;
try
{
Image img2 = Image.getInstance(tifBuffer); //cause
IllegalArgumentException
// creation of the document with a certain size and certain margins
Document document = new Document(new
Rectangle(img2.width(),img2.height()), 0, 0,
0, 0);
// creation of the different writers
ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(document, byteArrayOut);
SeekableStream s = new ByteArraySeekableStream(tifBuffer);
TIFFDecodeParam param = null;
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", s, param); //
cause
RuntimeException
logger.info("Number of images in this TIFF: " + dec.getNumPages());
// Which of the multiple images in the TIFF file do we want to load
// 0 refers to the first, 1 to the second and so on.
int total = dec.getNumPages();
document.open();
PdfContentByte cb = writer.getDirectContent();
for (int k = 0; k < total; ++k)
{
RenderedImage ri = dec.decodeAsRenderedImage(k);
Raster ra = ri.getData();
BufferedImage bi = new BufferedImage(ri.getColorModel(),
Raster.createWritableRaster(ri.getSampleModel(),
ra.getDataBuffer(), null), false, new Hashtable());
Image img = Image.getInstance(bi, null, true);
img.setAbsolutePosition(0, 0);
cb.addImage(img);
document.newPage();
}
document.close();
pdfBuffer = byteArrayOut.toByteArray();
}
catch (Exception de)
{
de.printStackTrace();
}
return pdfBuffer;
}
java.lang.IllegalArgumentException: The compression 6 is not supported.
