[hylafax-users] JBIG, v.34, ColorJPEG

["Ron Pettis" <rspettis@xxxxxxxxxxxxxxx>]

Hello!  New to this list...

Just recently replaced a "receiving-only" pool of color V.34 fax machines with some USR Sporsters on a Fedora Core 5 system running Hylafax 4.3.0 in Class 1.  The drives are a software RAID1.

It's been running beautifully for 2-3 weeks so we've opted to purchase Rockforce Duo+'s in order to once again take advantage of the v.34 speeds/compression.  We also figure that at the same time we'll implement the color capabilities of the previous setup.  (Our external sales force uses the color capability of their fax machines [HP 1240 Fax Machines] when faxing to us).

But before we install the new boards and go down this path, we've got a few questions.

Our existing setup receives the standard tiff-fax, does a tiff2pdf on it, and emails the PDF (via mSMTP) to our email server.

We're using the stock libraries (libtiff, etc) that ship with the distro, no modifications to any libraries.
My research on this indicates that we'll need to make changes to libraries and patch them, etc., as in:

http://www.hylafax.org/content/Handbook:Advanced_Server_Configuration:JPEG_and_JBIG_Faxing

I'm not sure I understand the step-by-step procedures to accomplish this.  Can someone steer me in a procedural direction what I must do?  The more research I do on this, the more confusing it seems to get.

Will a JPEG'd-tiff convert to PDF with tiff2pdf?  Will I instead need to tiff2ps and ps2pdf?  And will Adobe Acrobat Reader 6.0/7.0 display it correctly?

Also, what modem config file changes would be recommended, knowing our exclusive use of HP 1240's as senders?
Are the elements at the following site still relevant?

The goals are to once again have the following features:

1) Receive at the v.34 speeds
2) Use the modern compressions/error corrections
3) Honor the color capability and send color PDF's

Thanks!
