[Libreoffice-bugs] [Bug 98743] TIFF EXPORT saves weird image: in different x-y resolution and dimensions

--- Comment #24 from xordevore...@gmail.com ---
Created attachment 180750
  --> https://bugs.documentfoundation.org/attachment.cgi?id=180750=edit
original bug report's file, exported as a tif from paint.net

Paint.net uses three parameters with TIF exports:
a dithering level (1 to 8)
bit depth (1, 4, 8, 24, 32)
and a quantization algorithm dependent on selected bit depth (Median Cut,
Octree)

With me using paint.net's auto-detect setting, paint.net selected Octree for
the algorithm and a dithering level of 7 when re-saving the original bug
reporter's attachment as a TIF file.

Paint.net forces use of the octree quantization algorithm for bit depths 24 and
32, and the user is given the choice between octree and median cut for depths
1, 4, and 8, but does not report on the UI what the actual bit depth was if set
to auto-detect (but because Octree was defaulted, the auto-detected bit depth
had to be either 24 or 32).

Wild guess here, perhaps the engine you're using for the TIF export is not
reporting everything it's implementing during the export process and is locked
to a particular export format, or is using an optimization algorithm other than
the one paint.net is using (which wouldn't of itself be a bug, just a different
approaching to performing the export).

I did not see any visual difference between the original and paint.net's
export, so I'm not sure what information got lost between the original's 417K
and paint.net's 277K export.

I reverted the patch since it doesn't work with the file attached.
It's not normal that the nb of pixels drops.

I submitted a patch to just indicate that we use 96 DPI when exporting in TIFF.
https://gerrit.libreoffice.org/c/core/+/135631

As I indicated in the comment:
"Next step would be to use the dialog box for compressing options (like for png
or jpg).
But for this I think we should take benefit of external lib "libtiff" since we
now use it now for import."
but this part would take more time.

Sorry, this in no workaround, because with PNG the background of the pattern is
missing and JPG makes the the quality worse.
(see Comment #2 2016-03-18 21:17:55 UTC)

Six years later, there is still no "TIFF Options" window when exporting your
work from Draw into TIFF format. Still, the amount of pixels of the image drops
to one third, e.g. from 1000 to 350.

Which negates the entire point of having a TIFF export option at all in LO
draw.

This bug is similar to mine which no one's ever looked at

Workaround:  1. Export to PNG/JPG (setting values). 2. Open in image-editing
program that can save as TIFF.

Bibisect request is bogus. The resolution is always 2048x223 or 2048x302 pixels
when tested with older versions, Linux bibisect repos 43all (oldest, 3.5.0),
41max, 43max, 44max, 50max.

The bug reporter wrote that the tiff files exported by LibreOffice Draw 4.3
were correct.

LO 41max oldest- resolution 0,0172414 × 0,17 ppi. Is it really regression?

--- Comment #9 from Andrea Giudiceandrea  ---
Still an issue in 6.3.3.2 on Windows 7 64 bit.

There is no "TIFF Options" windows when exporting in TIFF format from Draw, so
it's impossible to set Width/Height/Resolution of the exported image.

Moreover, in the exported TIFF image file the x and y resolution parameters are
both set to very weird values.

--- Comment #8 from QA Administrators  ---
** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:
https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
