------- Hey,

I submitted a similar bug a while ago. (or was it just on IRC? Can't find the bug \
...)

I think this feature is really needed, but it can be kept as simple as possible. No \
need to save a complete editing history. The only thing that matters is to keep the \
original.

Suggestion:

- Let Digikam assume that pictures are not edited outside Digikam. There is no way \
for Digikam to know, and no user would expect Digikam to handle this.

- Upon calling an external editor from within Digikam, Digikam saves a backup copy of \
the file in .kde/share/apps/digikam/originals/originalfilename_md5(originalfile).extension. \
(To keep the name simple and outside the album tree, and to avoid collisions.) Or, if \
you want to keep you originals with the album, use albumpath/.digikam_originals where \
this path can be appended with some random chars (eg. ".digikam_originals_5ab3") if \
it already exists.

- When the external editor finishes, Digikam compares the backup with the original \
and if both are still identical, deletes the backup. If not, keep the backup.

- If an internal editor is called, we can just put the save_backup procedure I \
described in the internal editor's "Save" function.

- If a backup for a file exists (this can be cached in the database), provide a \
"Revert to Original" context menu item, and - perhaps - mark the image with a small \
image of a pen in one corner, so that it shows that it's been edited. The context \
menu item will just copy the original file over the current one.


Does this sound feasible?


Thanks!

Jens
