My requirement is to read the embedded ICC profile form the input JPEG

I want to know how this profile is embedded in JPEG file. Total file
structure.
Basically, see JPEG spec, ICC spec, and TIFF spec (as TIFF's mentioned
in your subject line).

This is all fundamental to the use of device profiles.

To wish for anything else is to misunderstand what profiles
are. Applying a profile is linking it and using the link.
OK, that's clear.
Marti, Graeme, thank you for your kind comments!

No, it does not. Managing the application of profiles is the task of
a color management system and LCMS is not a color

Does make sense to you?
Though I'm not an expert, your proposed workflow seems to always involve
the complete ICC setup, with more then one profile. You're always
translating an image defined by one profile, into a new image defined by
another.
This is not what I was

The fact that it can change the image
without embedding the icc profile in the image could be very useful
to me as the output image can be displayed in many more image viewers
than embedded information.
A similar need arises when looking at it from the point

Hi,
The problem both you mention is not trivial. Has to do with
what is known as color workflows and is one of the things
that IMHO makes color management so difficult.
So, I have no magic recipe to solve that, but here are
some guidelines I've successfully used when writting
imaging

BTW, Bob, I've been using the Rec709 YCbCr as default
for tiff images without problems. Any intent but absolute colorimetric should
handle white point mismatches, so even for D65 based image data seems to
works great.
In my case, the format is SMPTE DPX
