Summary: Add support for JPEG data precision 12
Platform: Fedora RPMs
AssignedTo: digikam-devel kde org
ReportedBy: kde ml shredzone de
Version: (using KDE KDE 3.5.8)
Installed from: Fedora RPMs
Please add support for JPEG images with data precision 12.
Rationale: Plustek film scanners are bundled with a scan software called SilverFast. This software supports 48 bit color depth. Anyhow it only allows to save the full color range as a proprietary TIFF file, or as JPEG with data precision 12. (Sadly there is no SANE driver for the Plustek scanner available.)
I would like to use SilverFast to scan with the full 48 bit color depth, but do the post processing (like color correction) with showFoto due to its superior algorithms.
I can provide test images upon request.
Medical pictures also seem to use data precision 12, e.g. for xray images.
This bug is somewhat related to bug 112801, but there it was only asked to ignore images with data precision 12.
