Re: [hylafax-users] Receiving empty white pages



Lee
Thank you very much for your reply.

I was trying to view these files on Windows using irfanview and photoshop, and photoshop did complain about unsupported compression method. You are right on target.

Being, hmm.. , a perfectionist , I wonder - is there any way to set up Hylafax to convert from JBIG to normal TIFF format ( no compression ).

Any response will be greatly appreciated.

Little be more info on a problem , while receiving JBIG compressed images on email from Hylafax I had this strange message


Does not look like a facsimile? ReceivedOn: ttyS7 CommID: c000000289


would this be caused by the JBIG compression?


Regard

Anton

If during the build process HylaFAX finds the JBIG-KIT libraries then Class1JBIGSupport is enabled by default. Otherwise it is disabled by default.

Over the past couple of months it has become apparent that some distributions include JBIG-KIT (I belive for the benefit of ImageMagick), and they do not use the JBIG patch for libtiff. This means that you'll be able to send and receive JBIG compressed faxes, but you'll not be able to view the received faxes (because you probably don't have anything that can view TIFFs with JBIG data).

So, the quick solution is to just disable JBIG support by adding:

Class1JBIGSupport: no

To your modem config file and restarting faxgetty.

Lee.
