Bug ID: 444052
Summary: While editing a raw (.DNG) image, original image can
be corrupted
Product: digikam
Version: 7.3.0
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: ImageEditor
Assignee: digikam-bugs-n...@kde.org
Reporter: dirk.vard...@web.de
Target Milestone: ---
SUMMARY
While editing a raw (.DNG) image, original image can be corrupted when using
external tool (RawTherapee)
STEPS TO REPRODUCE
1. Edit a .DNG image --> a) configure Image Editor to use 'RawTherapee'
2. Press F4 -> the image is loaded in RawTherapee.
3. Close RawTherapee, now the image is transfered to digikam editor (save
button is disabled!!).
4. Now do some modification within digikam editor, e.g.crop. After any
modification the save button is no more disabled.
5. Press save - this will save a corrupt image with original file name
(original is owerwritten!)
- The image is shown as TIFF format (thumbnail), but has still the
extension .DNG
- it has double the size of the original image
OBSERVED RESULT
in this special configuration a raw image is overwritten when saving within
digikam editor
EXPECTED RESULT
either 'save' button should be disabled to force 'save as'
or file selector should also pop up while clicking 'save'
--> this is the behavior when Image Editor Settings for 'Open raw files in the
image editor' is set to any other configuration, e.g. the default
configuration.
