--- Comment #6 from Julien Nabet  ---
On pc Debian x86-64 with master sources updated yesterday, I could reproduce
this.
I added some traces in HasAdequateCompression method (see
https://opengrok.libreoffice.org/xref/core/vcl/source/gdi/pdfextoutdevdata.cxx#800)
Whatever we resize the logo or not in LO, I always see the same values:
aSize.Width()=2000 aSize.Height()=439 rGraphic.GetLink().GetDataSize()=65280

I think we should test if there's been some resizing or not.
The pb is I don't know how to retrieve the resized values.

Repro.

The file size with version 3.5 is 7k with JPEG + reduce.

Is the problem on Ubuntu 5.2 as well? Then we could change OS to All.

Sorry, I now realise that the bug is not as easy as I thought to reproduce.

So :

1/ Take a jpg image (for example the one I attached, 4000 x 439 px ~ 64ko).
2/ Open a new odt document (A4 vertical for example).
3/ Insert this image in your odt and then resize it "a lot", for example to 2cm
in width.
4/ **SAVE** the odt (otherwise it won't bug.)
5/ Now you should have a ~73 ko .odt 
6/ Export as pdf and chose "Lossless compression" and "reduce image resolution
300dpi" you should obtain a ~9ko pdf (which seems normal).
7/ Do the same but with "JPEG Compression 90%" and still "reduce image
resolution 300dpi" you should now obtain a 66 Ko pdf (which isn't normal ...)

If you open the 66Ko pdf and copy the included image to GIMP you will see that
it is still the "full" 4000x439px image so it hasn't been reduce in size.

It seems that in certain cases the "reduce image resolution 300dpi" option
isn't taken into account.

Sincerely,

Sylvain.

Not sure to understand correctly what you mean. There is several bug report
about image compression in pdf export. For example bug 99723 and bug 100890.

Please could you describe more precisely your finding with numbers and a clear
step by step procedure to reproduce the problem.

Please attach a sample document with which you see the problem, as this makes
it easier for us to verify the bug. 

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' once the requested document is provided.
(Please note that the attachment will be public, remove any sensitive
information before attaching it. See
https://wiki.documentfoundation.org/QA/FAQ#How_can_I_eliminate_confidential_data_from_a_sample_document.3F
for help on how to do so.)

Best regards. JBF
