[comp.sys.hp] TIFF information/help

vic@zen.UUCP (Victor Gavin) (10/05/87)

I am using an HP ScanJet (Jet, huh?), with HP's Scanning Gallery.

I wish to take images prepared with the Scanning Gallery and include them
into \TeX documents.

At the moment Scanning Gallery is incomplete (ie missing most of the
capabilities promised), so I don't know what will finally be available.

What I am trying to do is convert a tag image file into a file of
HP LaserJet (?) escape sequences. I have received from Microsoft a
technical memorandum about what TIFF is all about, but no ideas on what
I'm supposed to do with the information in the file. I'm about to tackle
HP's response centre about some ``undefined'' tags used by Scanning Gallery
and at the same time try to get some information on decoding TIFF files
from them but I don't hold out much hope.

That is why I am (yet again!) calling to the NET for help.

Has anyone worked with TIFF, or better yet got a program that decodes the
image encoded into some format or other.

Alternatively, Scanning Gallery will (it says) print what it scans in onto
an HP LaserJet. It of course only prints to devices, so if anyone has a
device driver that will save what it receives into a file and are willing to 
give me a copy, I would be most grateful.

We have worked with TIFF, but are not at liberty to give you code.  I
would be pleased to help out a little via EMail.  Set one is getting
the spec itself.  I got mine from Aldus.  It defines the file format
and the tagged data.  Hint: the bitmaps are at STRIPOFFSETS.

Reading the tag files generated by a single application is easier than
being wonderfully general, and reading is easier than writing.  But
once you have the file format, the task isn't hard.
