TIFF File Compression

Postby Pankaj » Thu Jul 13, 2006 1:19 am

I am developing the FAX Server application in VB.NET to send/receive the FAX. While sending the FAX, we have to generate the TIFF File. I can generate TIFF File with following Compressions
1) No Compression
2) CCIT G4
3) CCIT G3
4) Deflate

Can any one suggest me, which is best compression for sending the FAX?
or which is the default compression for Black Ice FAX C++ SDK?

As arcosoft said before the CCITT Group 3 compression is the best for faxing.

Hi, hope this is the right place to post this.. I have a big (500+ MB) multipage TIFF image file and a database file which contains index to each image in the TIFF file. The scheme of the database is very simple.

imagename (text)
byte offset (integer)

So, it would list as

imagename, byte offset
mydoc1, 8
hisdoc99, 4795
herdoc88, 75890
and so on..

I've searched internet for accessing each image in multipage TIFF file, and only found methods to access image via page number, but not via byte offsets.
How can I access each page in this multipage tiff file via byte offset in either C#, VB.net ?
