These are the notes and important command lines that we learned today on how to build PDF files from TIFF (or other graphic format) files.
The test stuff is here: /var/www/dev/html/test/x
Here's the command to build the pdf:
htmldoc --header ... --footer ... --webpage --bottom 0 --top 0 --left 0 --right 0 -f jl.pdf a1.html 2> /dev/null
Here's what the HTML file should look like (a1.html in the above line):
Here is our first attempt at trying to convert the tiff to a gif. It works, except that it's inversed:
tifftopnm tiff.tif | ppmquant 256 | ppmtogif > GIF.gif
These programs are all part of the netpbm-progs-9.14-2 package.
HTMLDOC is the groovy package that converts html (and through it gif, jpeg, others) to pdf. It can do it both on Windows and on Linux. A command line version is available.
And this is the magic command line that makes it all work...
X=1/fred.img319.011; tiff2rgba $X x.tif; tifftopnm x.tif | ppmtogif > z.gif ; htmldoc --header ... --footer ... --webpage --bottom 0 --top 0 --left 0 --right 0 -f jl.pdf a1.html
It turns out that the Image Magick package works better than the netpbm stuff for what we need.
So here's a script that converts all of the listed files into one big PDF file using HTMLDOC and ImageMagick. Cool.

<html><head></head><body>

<img src="y.gif" width="100%" height="130%">
