Here is an example of what I mean. Maybe I should have
started off my first email this way ...
Inside the OIIO TIFFInput class, is the data member
private:
TIFF *m_tif; ///< libtiff handle
which is the fundamental libtiff structure for managing a tif file.
A wrapper library, such as OIIO, will expose some of the capabilities
offered by TIFF* and libtiff. By allowing the OIIO user/programmer
access to
the TIFF* (in a c++ civilized way), it would allow the best of both worlds:
-- The great uniform functionality of OIIO, and
-- For those willing to take the risk (compatibility with OIIO), further
functionality
available through the TIFF structure.
In my case, I am wanting to do geotif stuff. I suppose I could add a
new geotif
file format to OIIO, but it really is just a set of tif tags and the
such, so I think it
makes more sense to enhance the current OIIO TIF format implementation.
I would like to use libgeotif in conjunction with the TIFF* .
I would expect that many other image file formats have similar native
structures
that could be used to do stuff that is specific to those formats, so
this would be
a general mechanism to access such functionality.

I'm not quite sure what you mean by "native format functionality". Exactly what
data are you trying to retrieve?

I have looked through OIIO docs and source code,
looking for access to native format functionality that is not exposed,
or accessible, through OIIO -- for example, access to the TIFF structure
when dealing with tif files.
If such functionality, indeed, is not currently pat of OIIO, I will suggest in
a future email how to do that, and with feedback, would consider putting
in that effort of coding. It is not a lot of work. I think the issue is
whether
this should be considered, philosophically, to become part of OIIO.
Thank you.
