[ptx] autopano jpg png

[Beatriz Botero]

Hi:
I need some help with Autopano-Sift-2.4. The program does not not read 
my .jpg files. It only works with png-files, so I have to change the 
original photos from the camera from .jpg to .png. Furthermore I cannot 
use Exif in Hugin. The same files in jpg format can be handled in Hugin 
with the control points set up manually.
Using autopano from a shell delivers the following message:
------------ quote ---------------

$ /usr/local/bin/autopano-complete.sh -o /tmp/hugin.pto STA_0168.JPG 
STB_0169.JPG
Remaining arguments (2):
--> `STA_0168.JPG'
--> `STB_0169.JPG'
SIFT Keypoint Generation


Unhandled Exception: GLib.GException: Couldn't recognize the image file 
format for file 'STA_0168.JPG'
in <0x000a1> Gdk.Pixbuf:.ctor (System.String filename)
in <0x0002a> DisplayImage:.ctor (System.String filename)
in <0x000e3> GenerateKeys:Main (System.String[] args)
----------- end of quote -------------

Any help will be appreciated.
