Yes, Luminance HDR can use the alignment tool from Hugin. Which means
you have to have Hugin installed, if you need that feature. We cannot
demand that from our users.

A native function (or maybe a GEGL op?) would come in handy in quite a
few cases, including exposure combination (whenever someone writes UI
for that GEGL tool). Patches are welcome ;)

Hi,

If I correctly interpreted what I read and understood what Hugin 
algorithm does, then wouldn't it be more appropriate to adapt it to GEGL 
than making it a GIMP feature?

Photoshop have it and I miss it a lot.

In fact, I think we could use and existing algorithm. Hugin, a panorama
maker, have this function. And for example Luminance-HDR, an HDR picture
maker, have an option to use Hugin algorithm to autoalign pictures before
merge it.

Ok but may be we can have a fork of this algorithm integrated to gimp. With
this, no more hugin installation is needed, wright ?

I'm sorry but I'm a simple user and I don't know what is GEGL. sorry :-/


   Patches are welcome


Sure, but my problem is I don't know writing code. As I said, I'm just a
user. I talk about gimp around me the most I can. But that is my only
competence.

I ask this new feature here because I read somewhere on the bug tracker that
is better to ask for a new functionality here. Sorry if I'm wrong.

I use gimp for photography and very often on video, guys show how to do
something or something else with Photoshop. And very often this function is
called. So I'm not able to reproduce.

It let me two solutions :
- going back on Photoshop
- asking for this function on Gimp.

And I really, but really, don't want to going back on Photoshop.

Thanks

Marc
