thanks for your quick answer.

Those are very old news. iText now supports TIFFs directly, LZW and packbits

That sounds good. May you give some further information what "now" means? Which version of iText do I need.
I obtained the version 1.00 which is provided via an http link.
No planar mode and masks, though. See the package codec.
Is there any source code, how to use this class?
In the documentation which is provded online, only the old method (reading the TIFF by yourself) is mentioned.
You can also use Image.getInstance() but in that case only the first TIFF page is read.
This sounds good. How do I need Image.getInstance for an LZW compressed TIFF?
Can I create an Image for a tiff, than I would do for a PNG? In the current documentation it is still written:
"An Image is the representation of a graphic element (JPEG, PNG or GIF) that has to be inserted into the document".
Does this also mean TIFF?
Ciao Markus

Hi everybody,
i wonder if it is possible to write LZW-compressed TIFFs to an PDF using iText. As fas I know, PDF is able to decompress those LZW compressed TIFFs, so all I need to do is to put the binary data in PDF-file and to set information that it is a LZW compressed TIFF.
Using the example code http://www.lowagie.com/iText/examples/Chap0612.java it works perfectly for non-compressed TIFF images, when you use
img=Image.getInstance((int)w, byteswritten, (int)channels,(int)colordepth,im) getting the Image instance.
Is there any possibility to do it the same way with LZW or PackedBits compressed TIFFs? Will there be any support for these TIFF-file formats in the future? (I'm not asking that iText should decode and encode LZW-tiffs; only to write them as they are to the PDF....)
Ciao Markus Enders, GDZ
