I hope I am not annoying people by asking FAQs.
If I am, just point me to a FAQ guide.   Thanks.

I want to do JPEG compression inside a TIFF file.
I see there are tags for doing so, but I am unclear
how to proceed beyond this.  Sam Leffler's nifty TIFF
library doesn't appear to have code to do this, at least
in the version I picked up a few months ago.  Is there code
out there to do this, preferably that fits with the library?

Also, do any TIFF readers currently read JPEG?  XV doesn't
seem to.  I would like other people to be able to read the
files I produce.

Has anyone here done JPEG using JFIF?  This seems to be the more
popular way to do JPEG, but it appears to be a fairly stripped
format.  I would like to be able to include in the header my own
information (like ASCII strings to describe the image) but I have
no clue if this is possible or not.

Thank you for your help.
