https://bugs.kde.org/show_bug.cgi?id=252306 Summary: Tools Calendar creator - print to PDF file size for 12
pages 80-110 MB = about 30x larger than a year ago
Product: digikam
Version: 1.2.0
Platform: openSUSE RPMs
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general

Version: 1.2.0 (using KDE 4.4.4)
OS: Linux
When using Calendar creator > print to PDF file ( in both Gwenview OR digikam
same results ) I get an average PDF file size of 80MB-110 MB for a calendar
created with 12 pics half page, each jpg picture 1600x1200px 85% compression.
Each of the 12 calendar jpg photos has an average file size of 350-380kb. That
total calendar file size is a HUGE file size compared to identical PDF calendar
size last year being in the range of 2 - 6 MB only for a full identical
calendar.
.
I also did a test calendar using thumbnails only. with file size 3-4 kb per pic
and the full calendar still is 59.2 MB !!
When I open ONE such full size photo in konqueror/KDE and print the same photo
size 354kb to PDF directly (without calendar) then the PDF is 433kb ( picture
fills half page like in calendar).
It seems that somewhere in the calendar processing - BEYOND the regular KDE
print to file for pictures - the file size is artificially inflated.
This situation can be repeated and always results in same excessive file size.
I am aware that this years calendar image print quality is far superior to last
years, but comparing the regular print to PDF file size of a single image with
the calendar size it is obvious that there is a bug somewhere in calendar
printing (pre???)-processing when combining calendar plus images.
Reproducible: Always
Steps to Reproduce:
just take 12 wallpapers any kind, file size 1600x1200px jpg 85% compressed -
file size about 350-450 kb each
and print calendar to PDF file using any of gwenview or digikam
to compare "normal expected file size"
use any of the pictures used in a test calendar, in KDE and print to PDF file
without calendar - just KDE/konqueror
note normal file size of that PDF file
Actual Results:
File size oversized by factor 10-30 compared with last years PDF file size of
calendars with identical images used.
Expected Results:
A PDF file size (for this years improved image quality) in the range of 8-12 MB
