  Do showfoto and imageeditor have any significant differences in the
way they load jpeg files ? From brief glances at the code both seem to
use dimg in the same way. I ask this because:

1) I found one image that is correctly rendered by showfoto, preview
(f3 in digikam) and thumbnailer but the image-editor only shows 10%
from the top and then grays the rest.

I can email the image to someone if needed.

2) Putting QTime.start/elapsed across JPEGLoader.load, for the same
image showfoto is taking 200-400ms whereas image-editor is taking

If you want precise figures, I can provide them. These are all 4-5
MegaPix JPEGs from olympus digital camera, downloaded and edited by

I was basically trying to see why image-editor takes 5-10 secs to load
images whereas showfoto 1-2 secs. If you need me to run more
experiments, I will be happy to do so.
Thanks for digikam.
