[Bug 277206] New: problems exporting RAW (CR2)

https://bugs.kde.org/show_bug.cgi?id=277206

           Summary: problems exporting RAW (CR2)
           Product: digikam
           Version: 2.0.0
          Platform: MS Windows
        OS/Version: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Export
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.0.0
OS:                MS Windows

If I  open a CR2 file, do some small post processing in edit tab then import
and then save/export to folder . The cr2 can not be opened by digikam or other
apps (DPP, Zoombrowser) . this is using "all file" filer in exporting window .

Also if I sepecify any format jpeg, png etc and save to desktop the files are
really all tiff files according to infranview editor . size are huge 70mb where
caw cr2 are like 15mb .
Also if I saved the cr2 to same folder as orginal but i renamed it, only the
new one is shown in digikam folder window even though other editors show all
pics in folder . Maybe this is because there no new version option for raw
saving if in same folder ?

Reproducible: Didn't try

Steps to Reproduce:
just try and export a raw cr2 as above . open make some small change in post
processing. import and then export . new cr2 can't not be displayed

Actual Results:  
can't open newly saved/exported pic

Expected Results:  
should of save pic and open ok

Marcel,

I suspect a problem with versioning already fixed in Git/Master. Right ?

Ed,

Can you reproduce it with 2.3.0 release, or git/master implementation (next
2.4.0) ?

I am still on 2.0 install . Have not tried 2.3 yet but if you think it should
be fixed i can give it try or wait for 2.4 ?

I am on windows OS and need binaries/exe

Ok , using window 2.3 , open a Raw.CR2 pic, import, did minor edit and the
tried export and pointed to desktop . the file cr2 can't be opened by any app
now .
I then also tried import and then normal default save, this made a jpg in same
folder . can't read this file either .
Last I try save to tiff , this one works .

hope that helps
Ed

No, the orginal cr2 is unchanged sorry .
the saved cr2 file is 70mb in size , hmm
Edit the cr2 is really a tiff, I just renamed and it opened fine (this is the
saved/exported cr2)
Also on the tiff that was made if I try and export that to jpg , I get a jpg
compression window to set amount (didn't get that with default save) but when I
save to jpeg I can't open and it really is tiff file (same 70mb size)

So it seems all saved/exported formats are a tiff in reality

I'm lost.

You said that CR2 is a TIFF. yes it is but not in fact. it's a TIFF/EP plus
private tags and format from Canon.

You said that you change CR2 extension to TIF. Why ? you break type mime.

Can you open it with showfoto as well ? It's stand alone version of image
editor.

because the saved/exported cr2 would not open with any app , only when I
renamed it tiff did it open.

More info

hold on this is complicated . lets do overview as I am getting different
results opening the files with DPP and digikam .
Orginal cr2 opens with all . the default save file jpg (size 3mb)does not show
correctly and fails to open in digikam but opens and displays fine in DPP and
in infraview .
The saved tiff file opens and displays fine in digikam and infraview but not in
DPP (shows blank image with X throw it .

as for the cr2 , maybe don't let digikam save in cr2 format . I also have
rawtherapee and that converter doesn't save in orginal format (cr2) only tiff,
png, jpg formats .

There still odd behavior with jpg saving

There seems to be a general issue with opening jpg files in digikam . even ones
out of camera .
I don't know why but some jpg get a "fail to open image" message in digikam
when  you try to open .
But if I open a second time it loads ok , very odd .

Ahaha... Welcome to the club. It's reproducible under Linux. I don't use
Windows.

I can reproduce this dysfunction sometime on my lead computer (i5 2.4Ghz + 16
GB RAM)

In debug mode it's difficult to reproduce. In production mode, without debug
code, it's more easy to reproduce.

On my laptop, or a slower computer, it's not reproducible. It's a race
condition somewhere, but where ?

I already talk with Marcel about this problem.

You mean the "failed to open image" when opening the image editor for the first
time?
Any console output?
