Sorry if I'm repeating a recently asked question. The list archives
seem to have stopped they only show up to a few years ago. I spent
hours searching online and found nothing recent.
Question. It's now 2015, what's the current status of receiving color
(or grayscale... JPEG or JBIG) fax from, for example, HP OfficeJet Pro
8600 multi function fax/printer/scanner ?
Note: The HP officejet seems to send the page in JPEG format (T.30e ?)
(see info below).
I ask because, while Hylafax negotiates and receives a TIF file
successfully, and logs show a fully completed transmission, nevertheless
there are problems, because simple viewer apps throw errors, therefore
the TIFF image cannot be displayed, and the PDF file cannot be
generated. Unsure if the data inside got mangled or if it's usable.
IrfanView shows a black page, of the correct resolution, but a black page.
Searching the list and other message boards back to over ten years ago
(!) there is much reference to a need for a patch in libtiff and
libjpeg, back in 2001-2004 (!), then a make/compile rebuild the
libraries so that they can deal with the CIELab or ITULab color space
inputs properly so that a viewable TIF and thus PDF may be output by
HylaFax and shown in the web interface by AvantFax.
Is it possible that receiving color fax (jpeg) would have stagnated
before getting the 2 CIELab/ITULab patches into the mainline
distributions Libtiff and Libjepg, and stuck at that point for the past
10 years?
