[Libreoffice-bugs] [Bug 81593] Thumbnails of gallery are not in good resolution when add small svg file

--- Comment #15 from sergio.calleg...@gmail.com ---
The issue is actually not specific to svg files in any ways.

It also happens with drawings made with LibO itself which are saved to the
gallery, with emf files, with wmf files, with pdf files, in general with
anything that is rasterized to the gallery.

In fact, as indicated in bug 117330, the issue happens whenever the image being
pushed to the gallery is "small".

the problem is that the preview bitmap is taken at a fixed resolution ignoring
the drawing size. This is not the best thing to do as it results in wasted
resources when the image is big and in a poor rendering in the gallery when the
image is small.

Consider the following example:

1) A 10 inch X 10 inch vector object (e.g., a whole drawing) is placed in the
gallery. Assuming that the preview bitmap is taken at 100dpi (I do not know the
exact resolution being used), a 1000x1000 pixel bitmap is used for the preview.
When the preview appears in the gallery, given that the object will likely be
offered a 0.5x0.5 inch space, the preview will have a quite redundant 2000 dpi
effective resolution.

2) A small vectory symbol 0.25 x 0.25 inches is placed in the gallery. Assuming
that the preview bitmap is taken at 100dpi (I do not know the exact resolution
being used), a 25x25 pixel bitmap is used for the preview. When the preview
appears in the gallery, given that the object will likely be offered a 0.5x0.5
inch space, the preview will have a poor 50 dpi effective resolution.

Imho, the preview bitmap in the gallery should be created with a fixed number
of pixels on the x and y axis (e.g. 256), so that it always shows well when the
gallery is opened.

** 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

Unfortunately the problem is not yet resolved. 

I tried to test the old versions and noticed that it works to the last stable
version of the 4.0 branch, ie LibreOffice_4.0.6.2

The next versions add some functionality, but this option does not work well

I think it would be simple to add a setting in the Advanced Configuration of
the experimental features to adjust the thumbnail size option by placing a flag
'auto' that maintains the current configuration and the ability to set the size
in pixels of the thumbnail

Thanks for the reply but I can not insert the image in this way. I have a
number of sized images on a page and I have to add them one by one in the
gallery. Unfortunately, the thumbnails are ugly for the little image and are
good for the big image. I attached a file, the same svg file in the page if i
add the little the thumbnail are bad, if i add the big the thumbnail are good.
You can create a gallery and try. Thank you

J have attached a file  Example of file with the same image to add gallery

I can confirm the described effect. The quality of the preview depends on the
width and height attributes of the root svg element, not on the content. Insert
the attached pictures to the gallery (right click theme  item properties  tab
Files  find files  select with Ctrl-click  Add). Right click the imported
pictures  Preview.

Same picture with width=0.5cm and height=0.5cm

The only difference in the two files is in the outer width and height. Because
these are mapped to the same viewBox, there is no difference in the content.

Hi Sportegioco -

Two things:

1. Can you attach a small icon that you have tried and that is seen as
pixelated (as well as one that is seen as fine). This way we can see exactly
what you are seeing with the same exact image.

2. For the second issue, please report a second bug (the title being funky) -
always one bug per report.


Marking as NEEDINFO - once you attach the images please set to UNCONFIRMED.
Thanks for helping us out!
