Description pavel 2005-11-09 14:20:31 UTC

while investigating other issues, I found that contains zillions of
duplicated images. The following lists duplicated images (number of occurences,
MD5 sum):

    159 807dae78a1ec98d3ea5b3e32c98ffe90

generated as:

find . -type f -exec md5sum '{}' \;|awk '{print $1}'|sort|uniq -c | sort -rn

It seems unneccessary to include one image 159 times...

TM->requirements: please have a look.
Comment 2 ace_dent 2005-11-30 00:13:08 UTC
I would suggest that the 159x & 97x repeated images are the 16x16 and 32x32
versions of the 'green cross on blue background' icon.
Look at: ui/default_images/sfx2/res/ command.png & ln06.png.
I assume these icons are place holders? It is possible that the other repeated
icons are 'valid', since there are multiple copies of the standard tick, cross,
etc. in different project folders within ''... it would be nice to cut
down on some of the duplication by assembling the 'core' icons. Might also
relate to issue: 36518?
Cheers, Andrew.

To work towards optimizing OOo images, I have started an audit. It is currently
only an early draft, but I will post updates fairly regularly here:

Hopefully this work is of interest to developers of OOo. With 2.0.2rc1, the
'' archives now contributes *18MB* of the application size!!

duplicate of issue 66690 ??
Comment 6 pavel 2006-08-27 14:28:09 UTC
This issue is about reducing the reduncandy, not quality of images, so no, this
is not duplicate...
Comment 7 pavel 2006-12-03 13:16:14 UTC
Kai: are you interesting to work on this?

Although I have not updated the audit document in a while, the current link is:
If this work is useful I will continue adding to it.

I think to make this really work, it would be great to have a combined effort
with, so that a naming / icon standard can be formed for general
office / productivity suites. I'm happy to collaborate on this- with anyone!
Apparently the IconTool maintained by Sun's ArtTeam (Stella) stores contextual
information for the images- so this might allow redundancy to be reduced.

Maybe Stella could comment on the current state of the place holder icons (green
cross)- are they needed? Will icons be generated? If not, we should remove them
or at lest substitute with minimum size png images (67 bytes for 1pixel). With
current builds, one placeholder icon will now occur *8* times (default norm &
HC, industrial norm & HC, crystal norm & HC, and HiContrast norm & HC!!).

Look forward to feedback or signs of interest :-)

An idea:

1. remove duplicates
    - either via preprocessing the images list or via postprocessing the file

2. in case that image doesn't exist in the, consult duplicates.txt file in This file 
will contain something like:


Do you think it could work?

Comment 12 Rainer Bielefeld 2014-02-27 06:47:27 UTC
I wonder whether a cleanup already has bee done? I did some tests with very imperfect tools and did not fine "zillions" if Identical files. But nevertheless, found for "" osme possible duplicates:

(a) many imagename.png exist more than 1 time in the extracted file system.
    Examples: names_as_addressing.png 23 times, sc_underline.png 25 times
(b) A quick test with "sc_underline.png" shows that most of them have 
    different sizes, so they can't be identical. But I found several with
    identical size, let's take the ones with 408 bytes:
    really look identical to me, show a capital underlined U
(c) so due to (b) there still might be some necessity for a cleanup?

(d) My test (WIN 7):
(d1) extract  "" (from "\share\config") to a new folder 
(d2) from console from folder to where ""
     has been extracted  do 'dir /s /w > dir.csv'
(d3) open "dir.csv" with calc, copy / paste all rows containing a .png
     to a new sheet
(d4) In a new column with function like "=COUNTIF(D$1:D$10000;D4745)" 
     in row 4745 list number of found files with that 
     particular name in D4745
(d5) search extracted folders for a name with duplicates, sort hits by
     file size and compare files with the same name and size
(e) may be there are more powerful tools to find duplicates?
    My tests are rather "expensive".
