Subject: Re: I got a 360 camera
Thanks for sending me an example file privately.  Here's the
instructions on how to do what you want:

How to get an single image out of a panoramic image file, basically
using Hugin in reverse of what it's designed for:

1. Load your image with hugin in simple mode (it's the default mode
unless you've changed it) by clicking the "Load images..." button under
the "Assistant" tab.  Once you've opened the image set the lens type,
also under the assistant tab, to "Panoramic (cylindrical)"  that will
set the proper image type of your camera so that the program knows what
you feeding it.
2. Then click on the "projection" tab and change the projection type to
"Rectilinear".  You will see the preview look like the image is
destroyed... it's not, it's exactly what we need it to be, just move the
sliders at the bottom and side of the preview to zoom waaaay into the
very middle of the image and you will notice that the image will look
more like a regular photograph.
3. Now all that left to do is to click on the "Move/Drag" tab and pan
the image around till you get the image that you need.
4. Finally to get your image out of hugin click on the "Assistant" tab
and click the "Create panorama..." button.  Then set the "LDR Format" to
JPG or PNG (unless you really want a TIFF) and click OK.

Hope that helps,
Brian Cluff
