Re: [Qgis-user] QGIS SVG: outdated warning

[Matthias Kuhn]

I think Nyall will have some more information where things go right and
where they (can) go wrong.

Before improving the dialog text, we will need some insights into what
actually can go wrong and if we are able to predict that a certain
output is particularly prone to suffer from deficiencies.

As a second step we can write a message (or messages) that hints a user
towards potential problems (we see you are using blend modes, these will
be lost when exporting to format X, consider using Y instead) and give
task-focused suggestions (if you want to further edit the result or use
it for interactive web-publishing, use SVG, if you use it for printing
and static presentation prefer PDF).

None that are not already in the note on

http://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu

ie. wait for the next nightly after a ubuntugis update.

qgis=1:2.18.14+git20171125+e541a38+24xenial-ubuntugis from
ubuntugis-nightly-release depends on gdal-abi-2-2-2.

Re: [Qgis-user] QGIS SVG: outdated warning

[Patrick Dunford]

It looks a lot better in master than I used to remember from way back (I 
started at 1.8). Maybe Qt have done some work on it.

So not sure what it is exactly that I have to do to fail.

The only difference is that in master I do not get the 'let's print in

So what about: keeping the dialog (as I think at least for SVG the
outcome will never be what a designer wants (id's, layers as layers etc
etc), but change the message to: "Both pdf and svg exporting is done via
the Qt-library. Results can vary based on complexity of (painting) of

IF in future certain rendertasks appear to screw up either svg or pdf we
can always add those?

Yeah, that confused me ;)

I wonder, why creating is done by Qt at all. Cairo might be a better
solution. But I can't help at that point :(

Hi Angelo,
is there any chance that you could synchronize your efforts a little bit?

It's really strange that shortly after the new QGIS point release, the
dependencies get changed.
If this would happen just once in a while, I wouldn't complain at all.
But this feels more like coordinated chaos ;)



My workaround is Ubuntu artful in a virtual box, which installs 
qgis-nightly without complaints.

It means PDF. I don't recall there ever being a postscript option.

QGIS2 uses QT5 and there's no PostScript export support anymore ;)

Re: [Qgis-user] QGIS SVG: outdated warning

I have produced a number of maps that are exported to produce vector 
graphics that can be inserted into a word processing document to make a 
multipage document. Here there were a lot of issues with the lines 
changing thickness and styles when the SVG export was used. The PDF 
output was much more consistent.

Re: [Qgis-user] QGIS SVG: outdated warning

[Tobias Wendorff]

Hi there,

even on EPS, PS or PDF, output with effects never really work pretty
well. Some flavors of those types don't accept transparency at all.

Actually, I never wanted to remove  the warning. Please keep the
dialog, just update the message. Perhaps a more neutral warning
should be better, like you suggest.

I just was curious because I didn't find EPS/PS export support at
all and this made me wonder about the dialog's content.

Best regards,
Tobias

Re: [Qgis-user] QGIS SVG: outdated warning

[Tobias Wendorff]

Hi Richard,

no, I was talking about QGIS2 (stable), but I was wrong about Qt5,
I'm sorry. I've looked for Qt5 libraries installed only and didn't
check that QGIS2 still uses Qt4. I don't have a clue, why the
installer installed Qt5 anyway.

QGIS2 doesn't have EPS export, does it? I can't find it anymore.
Perhaps I'm looking at the wrong menu again...

Best regards,
Tobias

Hi Matthias,

whoops... I just checked the installer again and Qt4 AND Qt5 are
selected. I just checked for Qt4 last time.

But there's no more EPS export, so the message should be updated.

Re: [Qgis-user] QGIS SVG: outdated warning

[Richard Duivenvoorde]

I added some layers, some blending and transparency, but to be honest
both in 2.x and 3 outcomes (pdf and svg) were more or less ok to me
So not sure what it is exactly that I have to do to fail.

The only difference is that in master I do not get the 'let's print in
raster...' when printing a pdf.

So what about: keeping the dialog (as I think at least for SVG the
outcome will never be what a designer wants (id's, layers as layers etc
etc), but change the message to: "Both pdf and svg exporting is done via
the Qt-library. Results can vary based on complexity of (painting) of
you map, but cannot be influenced by QGIS itself." or so?

IF in future certain rendertasks appear to screw up either svg or pdf we
can always add those?

Regards,

Richard

 QGIS2 uses QT5 and there's no PostScript export support anymore ;)

Hi Hisham,

I don't know a QGIS-Plugin, but if you use QGIS with PostGIS, you have more
options.
2 approaches with PostGIS are:

ST_ApproximateMedialAxis  >>

ST_StraightSkeleton  >>  https://postgis.net/docs/ST_StraightSkeleton.html

Hi Bernd,

Coordinating this kind of work is hard, if not almost impossible in my view.

It is easier to warn a user (just like apt is doing with you): "hey
apparently that package is temporarily broken because it is dependent on
that one, while that one is not yet updated".

This is exactly what the message is that you are seeing. It is warning
you that you should not FORCE the update, but have to wait some time
(days?) so all dependent packages are on par too.

So the message you get is not a message of a 'broken system' but more
'this part is in flux, but hold on, we are working on it'.

It is not chaos, it is reality (while some people think a shiny outside
or hidden transparency is the same as an ordered system :-) )...

Please have that trust in the volunteers,
OR else take the steering wheel yourself, and offer help.

Regards,

Richard Duivenvoorde

Re: [Qgis-user] QGIS SVG: outdated warning

[Matthias Kuhn]

Hi Richard,

In this case I was confused by the term stable in the previous message.

If this is still there on 2.99, can you check if SVG export also works with

* Transparency

* Layer blend modes

IIRC, these were the tricky things.

Thanks  a lot

Matthias

Dear Bernd,

The transition of GDAL has been communicated in the UbuntuGIS mailing 
list since Nov 7:

https://www.mail-archive.com/ubuntu@lists.osgeo.org/msg01406.html

Also, the hint that the maintenance team (volunteers) is trying to break 
QGIS packages on purpose is totally unacceptable.

Hi Angelo,
is there any chance that you could synchronize your efforts a little bit?

It's really strange that shortly after the new QGIS point release, the 
dependencies get changed.
If this would happen just once in a while, I wouldn't complain at all. 
But this feels more like coordinated chaos ;)


Thanx for your work

[QGIS-it-user] Visualizzazione s-52

[Francesco]

Buongiorno a tutti, ho creato in qgis un progetto con un file vettoriale di una 
carta nautica .000 . Una volta importata ovviamente non ho la visualizzazione 
secondo lo standard s52 . Come posso fare a visualizzarla secondo questo 
standard? ( s52 o s57) .

Ho trovato solo questo link: 
https://grasswiki.osgeo.org/wiki/S-57_data#QGIS_S-52_plugin_for_viewing_S-57_data
