Summary: default compression rate for Jpegs looses data, should
be set to 100% quality by default
Product: digikam
Version: unspecified
Platform: SuSE RPMs
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: digikam-devel kde org
ReportedBy: sven.burmeister gmx net

Version: (using KDE KDE 3.4.92)
Installed from: SuSE RPMs
OS: Linux

I think that the user should not by default loose data when editing pictures. Hence the default-value for Jpeg-quality should be 100% and not 75%.

I think this bug report isn't correct.

1 / JPEG isn't a lossLess image file format.
2 / LossLess file format is PNG or TIFF.
3 / Jpeg compression factor to 100% isn't lossless.
4 / Jpeg is dedicaced to web publish, not image edition.

If you want more information about image file format supported in digiKam, please take a look in current handbook (0.8.0 from svn).

Regards

Gilles Caulier

You're right Gilles, but this discussion comes up again and again, so why
shouldn't we change it to a 100% default? People are satisfied and who reads
the manual knows it better ;-)
