[ptx] PTtiff2psd

[Daniel M. German]

Hi everybody,

I have been a bit busy and haven't been able to work on libpano as
much as I'd like. 

Last night I finally had time to test my last program: PTtiff2psd 

It is a program that merges 8 bit TIFFs into a single Photoshop PSD
file. I think you will find it useful. Again, it only supports 8 bit
TIFFs.

Last night I generated a 360 degrees panorama using PTmender:

I took 7 photos with the Canon EF-S 10-22, the camera was at the level
of my waist (I was standing), with manual focus (I did not look
through the viewfinder), and I tried to rotate the camera around its
nodal point (I did not have my panorama head with me nor a tripod).

The workflow was:

* Use 7 JPEGS as generated by my camera (small size, low resolution)
* Use hugin to create control points, generate PTstitcher script
* Run PTmender
* Run PTtiff2psd
* Fine tune the seams using photoshop. Flatten, enhance contrast,
  crop, resize for publishing.


The results are very encouraging, given that this is 360 degrees
panorama. The seams are visible at the top mainly because I used the
small JPEGs that my camera generates along the RAW files (my laptop
can't cope with very large files).  Unfortunately I forgot to set the
colour balance to non-automatic. This makes the seams visible. Other
than that they are very few defects (mostly on the floor, where it is
most expected).



One tool that would be really useful (and I might write) is a program
that takes a Hugin file and a PTstitcher script and remaps their
coordinates to a different resolution (for instance, now that I have
worked with these small JPEGs, I'd like to reuse the control points
with higher resolution pictures without having to do it all over
again).
