Quick answer, this should be just another Image subclass. Depending on 
how different the file format is from what we already have, it will 
take more or less effort to implement. (Did a brief search but couldn't 
find a good description of the format, most sites talk about the image 
data compression, which Exiv2 would simply skip).

Just my investiguations : look in recent Exiftool source code, it support Exif 
extraction from JPEG 2000.

Also, i'm looking to support in native PSD file format in digiKam (photoshop) 
witch support EXIF, IPTC and XMP. This one is very used by photograph, and 
i'm sure that it will be very important to give an Exiv2 support it in the 
future. Your viewpoint ?

I think no. Perhaps in the future.. To have take a look into Jasper source 
code, i have seen that encoding algorithm require a lots of CPU ressources. 
In fact more than JPEG.

I suspect 2 problems with JPEG 2000 algorithm :

- it require high CPU speed.
- The gain with low compression ratio is not sugnifiant than JPEG

This is why camera do not use it actually. Perhaps in the future the embeded 
CPU used in DSC will be more powerfull for that.

It more easy by maker to implement a fast JPEG encoder or a RAW file format 
(witch is uncompressed). First use in 8 bits color depth, second 16 bits.

ok, this is the problem :

[Color Management]
BPCAlgorithm=false
BehaviourICC=false
CMInRawLoading=false
DefaultPath=$HOME/Desktop/icc
EnableCM=true
InProfile=0
InProfileFile=

==> there is no ICC file set like Input profile !

ManagedView=true
MonitorProfile=4
MonitorProfileFile=$HOME/Desktop/icc/Monitor Gamma 2.2.icc

ProofProfileFile=$HOME/Desktop/icc/fsnEnduraSupraGlossyV2.icc

WorkProfileFile=/usr/share/apps/digikam/profiles/srgb.icm

Normally it's impossible to use CM without an input ICC profile.

[Bug 138200] New: WISH : Display all pictures when no tag is selected instead of no picture

------- You are receiving this mail because: -------

http://bugs.kde.org/show_bug.cgi?id=138200         
           Summary: WISH : Display all pictures when no tag is selected
                    instead of no picture
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: ryfe.972 gmail com

Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages
OS:                Linux

Hello everybody,

When I open Digikam, I would like to see ALL my pictures (actually all the thumbnails) in the main board
instead of juste a blank giant field with nothing visible.

In other words, when NO tag is selected, I would really appreciate to have all my pictures Digikam actually
manages (ranked in chronological order or the contrary).

I don't know if that's what is meant here and I hope my wish is compatible with this one.

Hello everybody,

I realized I didn't understand well this wish report. So my first Additionnal comment is irrelevant.

I opened a new wish to express what I meant :

I don't have an input profile for my camera, or any other input profile for testing. So I had to leave it blank.

Thanks for looking into the problem!

Are you working with JPEG or RAW files ?

Witch bits color depth you use to decode RAW files ? 8 or 16 ?
