Thread: 2D compression  (1/5)
  Date: 24-Apr-97, 10:12am  (Ref# 5277)

Hi All!

I recieved a fax yesterday with 2D compression.

Needless to say it was illegable.

Since view.exe doesnt support 2D compression, is there any way I can view this
fax?

Thanks!

You can use the ZFAX program, available from ZyXEL's web site, to view
faxes compressed with 2D encoding.
 
You should be able to disable the receiving of 2D faxes (which will force
a fallback to 1D mode) to prevent this problem in the future.
 
(Unless you are using a ZyXEL specific mode, which I believe there is a
bug that prevents the disabling of 2D encoded faxes.)

Actually, I changed versiosn to 1.70, from 1.55 and suddenly view.exe was able
to view the fax much much better...still gave me a warning though.

Yes, some (very slow) work has been done with 2D stuff, but I still am
having a hard time figuring it out.  The reference documents I have are
horrible (the T.4 documents never show a complete scan line that is
decoded, only partial decodes), and the source code from other fax
programs I've looked at are nearly incomprehensible to me.
