saving bixbuf with imlib, image distortion

[Thomas Amsler <tpamsler ucdavis edu>]

I am still trying to save a pixbuf with the help of imlib. I cut/past
the the method below.  Once I save the pixbuf, I still get a distorted
image, everything is screwed 90 degrees. I read in one of the replies to
my earlier posts about the different pixbufs that either include alpha
or don't.  I am confused about this since the description that comes
with imlib on using the structure GdkImlibImage is the following:

"These are the image data structures. You may read all these data
members, and you may edit the data that rgb_data and alpha_data point
to. Remember that if you modify this data to call
Imlib_apply_modifiers_to_rgb or gdk_imlib_apply_modifiers_to_rgb to
dirty the pixmaps in the cache. You may not free this data or change the
pointer. Currently the alpha_data member is unused and will remain NULL.
Setting it to anything else may produce unexpected results."

They seem to say, go ahead and change alpha_data in one sentence and
then they say that the alpha_data member is unused???

Can someone tell what I am doing wrong here.  Thank you very much for
all your help.
