[Digikam-users] Digikam 2.9: Save image comments to file

Thu Oct 11 11:29:53 BST 2012

Hi,

thanks for your help, I made at least a littele progress.
Firstly,  the output of "Components Information":
--------------------------------

digiKam version 2.9.0

Exiv2 can write to Jp2: Yes

Exiv2 can write to Jpeg: Yes

Exiv2 can write to Pgf: Yes

Exiv2 can write to Png: Yes

Exiv2 can write to Tiff: Yes

Exiv2 supports XMP metadata: Yes

LibCImg: 130

LibClapack: internal library

LibExiv2: 0.23

LibJPEG: 62

LibJasper: 1.900.1

LibKDE: 4.9.2 "release 511"

LibKExiv2: 2.3.0

LibKGeoMap: 2.0.0

LibKdcraw: 2.1.0

LibLCMS: 119

LibLensFun: external shared library

LibLqr: internal library

LibPGF: 6.12.27 - internal library

LibPNG: 1.4.11

LibQt: 4.8.3

LibRaw: 0.14.6

LibTIFF: LIBTIFF, Version 4.0.2 Copyright (c) 1988-1996 Sam Leffler Copyright (c) 1991-1996 Silicon Graphics, Inc.

Marble Widget: 0.14.1 (stable release)

Parallelized PGF codec: No

Parallelized demosaicing: Yes

Database backend: QSQLITE

LibGphoto2: 2.4.14

LibKface: 2.0.0

LibKipi: 1.6.0

LibOpenCV: 2.4.2

Libface: 0.2

--------------------------------

It seems to contain everything.

In the mean time, I figured out that saving comments with language 
"x-default" works, but using "lang=de-DE" does not. When saving the 
title, the language does not matter.
Here's the debugging output for both cases:

1) Using "lang=x-default" (working)
--------------

digikam(3612)/digikam (core) Digikam::DMetadata::setImageTitles: "/home/user/bilder/DSC_1229.JPG"  ==> Title:  QMap(("de-DE", CaptionValues::caption: "mytitle", CaptionValues::author: "", CaptionValues::date: QDateTime("")  ) )

digikam(3612)/digikam (core) Digikam::DMetadata::setImageComments: "/home/user/bilder/DSC_1229.JPG"  ==> Comment:  QMap(("x-default", CaptionValues::caption: "mycaption", CaptionValues::author: "", CaptionValues::date: QDateTime("Thu Oct 11 12:24:26 2012")  ) )

--------------

2) Using "lang=de-DE" (not working)
--------------

digikam(3612)/digikam (core) Digikam::DMetadata::setImageTitles: "/home/user/bilder/DSC_1229.JPG"  ==> Title:  QMap(("de-DE", CaptionValues::caption: "mytitle", CaptionValues::author: "", CaptionValues::date: QDateTime("")  ) )
digikam(3612)/digikam (core) Digikam::DMetadata::setImageComments: "/home/user/bilder/DSC_1229.JPG"  ==> Comment:  QMap(("de-DE", CaptionValues::caption: "mycaption", CaptionValues::author: "", CaptionValues::date: QDateTime("Thu Oct 11 12:23:48 2012")  ) )

-----------------

At least now I know how to do a workaround by using only x-default. 
However it would be great to get de-DE to work since I don't want to 
switch the language of ~3000 captions by hand.

Regards,
Markus
