And one last: a direct sys-dep renderer could create the 16x16 pattern but
could just paint it, even when 16mio times - would not need to create matrix
and primitive instances. Still, that does not touch the basic problem of just
too small pattern elements...

Comment to comment 11: Already correct to go, just wanted to mention that what
I saw in dbg with unchanged scale the pattern gets a view-dep size of 16x16
pixels, so not sure if that should be reduced more.
Maybe a mix of limiting scaling and enlarging BM by repeating would be good. In
this case e.g using 10x10 patterns in a bitmap going to 160x160 and reducing
the scale by 1/10th...

Made a short check what's going on. Generic sys-dep renderers would be ideal
(and were always the target after cont'ing the changes) but would not help too
much here.
The PatternFillPrimitive2D already does a decent, discrete (res- and target
dependent) buffered decomposition. Did that once for a similar case - the
pattern is tran'd to a bitmap and embedded in a stack of matrices to reflect
the fill (done based on discrete pixel size of pattern back-transformed to have
no gaps in pattern :) important).
In this case the range and size of the pattern derived/imported from the SVG
lead to creation of 2mio sub-primitives - argh! Either there is an error in
this file or we need to limit amount of decomp parts anyways due to mem overrun
attacks...
Just my 2ct

That is a reasonable idea - the other option is to teach the renderers to
handle  PatternFillPrimitive2D without decomposing it.

--- Comment #12 from QA Administrators  ---
Dear librereporter,

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

Not fixed for me with Version: 6.1.0.0.alpha1+ (x64)
Build-ID: 439f17c5cf43b38092b1b834bb006420220262e1
CPU-Threads: 8; BS: Windows 10.0; UI-Render: GL; 
Gebietsschema: de-DE (de_DE); Calc: CL

The problem is the patternTransform attribute in the  element. If I
set the scaling factor to 0.163399, there are no problems. With scaling factor
0.0163399 I get high computer workload, but in the end it is rendered and on
high zoom the circles are visible.

factor 0.163399 means about 30×30=900 circles to be rendered.
factor 0.0163399 means about 300×300=9 circles to be rendered.
factor 0.00163399 as in the attached "simplifier sample" file means about
3000×3000=900 circles to be rendered.

I think, there need to be a cut, so that if the to be drawn circle becomes
smaller then a threshold, it is no longer drawn as circle. Ersatz might be
solid filling with a color with transparency, which considers the percentage of
the filled area.

I cannot confirm, that it worked before version 3.6. In version LibreOffice
3.5.1.2 Build ID: dc9775d-05ecbee-0851ad3-1586698-727bf66 the graphic is not
rendered at all.

Not fixed for me (LO hangs), tested with latest commit of bibisect-win32-6.1 as
of today (ac27f4e7abf5339f71d4f5f3fc09a13b25669fe4) in Windows 7.

Still not fixed with Version: 6.0.4.2 (x64)
Build ID: 9b0d9b32d5dcda91d2f1a96dc04c645c450872bf
CPU threads: 3; OS: Windows 6.1; UI render: default

Could anyone backport it ?
