            Bug ID: 306371

           Summary: Rename with sequence number
    Classification: Unclassified
                OS: Linux
          Reporter: ivarness76 at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: Advanced Rename
           Product: digikam

There is no good way to deal with sequence number in the rename option.
Camera model used Canon 500D. (tested for both image raw (.CR2) and
converted(w/embedded option) (.DNG) files.

Standard camera file name: _IMG4561.CR2 ... _IMG5461.CR2 

(1) It is desired it to preseve the seqence number of the original format, with
out the _IMG.
(Request) Perhaps an regexp option/filter on the [file] would be an elegant
work around.

(2) Attempts to used EXTIF information failed.
None of these returned any value: (other EXTIF data like Exposure was
obtainable)
[meta:Exif.Image.ImageID]
[meta:Exif.Image.ImageNumber]
[meta:Exif.Photo.ImageUniqueID]
[meta:Exif.Canon.FileNumber]
[meta:Exif.CanonFi.FileNumber]

(Request) fix? + 
Believe there ought to exist an additional [meta:Exif.Canon.FileIndex] that is
not included
in list (using it did not help, put suppose it is not extracted?).
http://search.cpan.org/~exiftool/Image-ExifTool/lib/Image/ExifTool/TagNames.pod#Canon_CameraInfo500D_Tags

(3) Further more when selecting all photos (800+) and attempting to add
METADATA
tags the application/UI "freezed" for ~2 days before recovering operation. 
(Request) Perhaps the update meta tag process ought to be worker thread and
abortable.

(4) (Request) It would also be nice to have a undo (rename) + confirm dialog if
you just accidently hits enter when working on the renaming options.

Reproducible: Always

Steps to Reproduce:
1. Select 800 photos for rename
2. Used follow advanced rename:
[date:"yyyy_MM_dd_T_hh:mm:ss.zzz"]_#_[meta:Exif.Image.ImageID]_[meta:Exif.Image.ImageNumber]

Actual Results:  
When appending meta info the application freezed for 2 days. (no responsive)
Meta tag relating to ID sequenceing returned nothing, the additional # came out
as resevere 
order of filename although this seems to be adjustable by correcting sort order
prior to rename (not documented)


Expected Results:  
UI update should be a background process and possible abortable if taking to
long time.
Some of the tested meta tag ought to return the original image sequence number.
