Testing with ImageMagick 6.9.12-38 on an Illumos system shows the image the

right way up is.
It appears that ImageMagick 6.9.10-23 and 6.9.12-38 do not display the same
output!
Thankfully this issue brought my attention back to TGA format. I
found that an unnecessary security check was blocking reading some
files entirely. I also noticed that the code could be optimized a
bit.
However, I believe that this bug report is incorrect.
What has actually happened is that ImageMagick changed what it
returns and more recent ImageMagick also changed what it does when it
displays an image.
GraphicsMagick always returns an image in the common normal form
(TopLeft). ImageMagick changed so that it returns an image in the
same form as the file, but it sets an orientation option so that the
user needs to use -auto-orient to see a correct image.
In the older version of ImageMagick, the 'display' program does not
appear to automatically adjust the orientation where as the newer
version does.
This morning I committed the TGA improvements and created a new
development snapshot release.
