Re: [Qgis-developer] SRS DB maintenance

2013-07-04 Thread Werner Macho
Hi!

As I had some problems with non existing EPSG Codes in the srs.db
lately too .. I support Radim here ..
It seem's that something is going wroing here .. While most of the
world is covered not all EPSGs are available or being overwritten ..

Isn't there an official latest database that we can just take? Or
try to make it easy for the user to update the db if connected to the
internet sync db on QGIS start or something like that?

kind regards
Werner

 That's why I usually point people to GDAL instead of adding it to our 
 database.

 I can't tell if anything in our database is/was a better definition than what
 GDAL has or if anything we have and GDAL doesn't is necessary or useful to
 anyone or just cruft.

 There are new EPSG and towgs84 params for 5513, 5514, 5221,
 2065,102067, 4156 and 4818 in QGIS but they are deleted/overwritten by
 wrong values from GDAL by crssync (at least in weekly build for win).
 Until we manage to push them also into GDAL, I need to preserve
 somehow the correct values from resources/srs.db.

 All definitions that are unique to QGIS are left untouched and everything 
 else
 is overwritten with what GDAL (for EPSG) or PROJ.4 (for non-EPSG) has.  So 
 the
 final srs.db wouldn't be any different from what is now used now, would it?

 Unfortunately no, the new EPSG codes which are not in GDAL are deleted.

 The point is that it's not tied to any particular version of GDAL/PROJ.4 (and
 we use various versions across all the platforms and distributions).

 IIRC keeping our srsid is also important in some cases - so starting a fresh
 database from whatever GDAL/PROJ.4 version is installed, isn't that easy
 either.

 I agree that the current CRS handling (and that IMHO not only applies to the
 srs database) is far from optimal, but we didn't come up with anything better
 so far and the current approach is at least easy to maintain.

 It seems to be impossible to be maintained. I have correct EPSG codes
 but no way to get it into distribution.

Brilliant. Why didn't we think of that before - and we can also reduce the
cluttered QGIS UI to a single DWIM[1] button while we're at it. ;)

7805af3cf introduces a noupdate field in tbl_srs, that is set to 1 for the
mentioned CRSes.  And crssync doesn't update or delete records marked like
that.  But that flag should probably tracked somehow and set to 0 eventually,
when the CRSes get corrected in/introduced to geotiff/GDAL/proj.4.

did not know what has already been looked at .. I took the easiest
thought that I had ..
I also know that it is not easy .. but .. as Radim also said .. there
are problems .. somehow ..

But thanks for the insight into crssync and the noupdate field .. :(

[Qgis-developer] new icons

2013-07-04 Thread Denis Rouzaud

Hi all,

I have been redrawing a few PNG icons last days.
I have already changed the identify and action icon as shown on the 
right of the printscreen.


Two commits are on their way to get accepted for selection and system icons:
https://github.com/qgis/Quantum-GIS/pull/693 
https://github.com/qgis/Quantum-GIS/pull/693/files

https://github.com/qgis/Quantum-GIS/pull/692

I think the pan icons are a more debatable point.
I tried 2 news designs.

Could you tell what you think about them?
1. Keep current
2. Hand style
3. Pad and arrow style

Of course we can have a combination, so please specify pan or panToSelected.

I think it's a good time to update these icons, and will give QGIS a 
fresh look for 2.0.
I took the initiative of doing so on my own. I started with two awful 
icons (identify and action), and I felt like going on So if you 
think things should not be changed, please say it, so I won't spend too 
much time on this.

And if you like the changes, you can also say so ;)

Greetings,

Denis

each one is for a different territory but the same CRS. While the

Re: [Qgis-developer] SRS DB maintenance

2013-07-04 Thread Marco Hugentobler

While the
relation between CRS and transformation in EPSG database is
(naturally) one-to-many, QGIS oversimplified the relation to
one-to-one



We should probably
separate CRS from towgs84 and allow users to choose from multiple
towgs84 for CRS.


We have a similar problem here with multiple transformations between two 
coordinate systems (ntv2 based transformation more accurate in that case).
So I was also thinking about enhancing the coordinate transformation 
class to store transformations in a table (import from epsg 
transformation info) and let the user select the transformation in case 
several exist. QgsCoordinateTransform would then adjust the proj-strings 
of source and dest CRS on the fly.


What do you think about such a solution? It looks like I have the 
possibility to work quite soon on such an enhancement.


Regards,
Marco

 We should probably

 towgs84 for CRS.

 We have a similar problem here with multiple transformations between two
 coordinate systems (ntv2 based transformation more accurate in that case).
 So I was also thinking about enhancing the coordinate transformation class
 to store transformations in a table (import from epsg transformation info)
 and let the user select the transformation in case several exist.

Where do you want to let user select the transformation? In my opinion
it should be possible everywhere where CRS may be selected (including
OWS dialogs). That means not to have one global transformation set for
user or project because it may happen that it is necessary to work
with data with different transformations in a single project.

 QgsCoordinateTransform would then adjust the proj-strings of source and dest
 CRS on the fly.

Is it possible to do it without API break?

 What do you think about such a solution? It looks like I have the
 possibility to work quite soon on such an enhancement.

[Qgis-developer] Labels from loadNamedStyle()

2013-07-04 Thread Stott James
Hi,

Is anyone else still having problems with this bug 
http://hub.qgis.org/issues/6468?

I am writing a standalone python program, and my code loads a style from a .qml 
file, but the labels do not display when the maps are rendered to a .jpg.

The polygons have the correct styling (border etc), but not the labels. I am 
using new style labeling.

The labels load correctly within QGIS GUI, but not in the python code.

I am using QGIS master from OSGeo4W, updated today.

Thanks

Re: [Qgis-developer] SRS DB maintenance

OWS dialogs). That means not to have one global transformation set for
user or project because it may happen that it is necessary to work
with data with different transformations in a single project.


Good point. Probably the user should be asked if setting/changing CRS of 
a layer or if user changes the map CRS (in that case he is asked for all 
layers). It might be a bit of a useability challenge to make this user 
friendly (especially for users who don't bother about transformations).



Is it possible to do it without API break?


I hope it is possible to enhance QgsCoordinateTransform with additional 
methods (reading transformations from sqlite, reading/writing to project 
file, etc...). My guess is that it is possible without break.

Marco

Is there any technical problem not to display that file format? If not, I

for panToSelected, instead of rotating the hand you could try to just leave it 
like pan and add the selection box, that way it will eliminate the select by 
click effect I think

 Hi Denis,
 
 thanks for your effort.

 panToSelected with hand looks like select by click to me, so +1 to 
 keep current (symbols IMHO need not be similar as panToSelected is a 
 button and pan is a tool)

  Could you tell what you think about them?
  1. Keep current
  2. Hand style
  3. Pad and arrow style
 
  Of course we can have a combination, so please specify pan or panToSelected.
 
  I think it's a good time to update these icons, and will give QGIS a

  I took the initiative of doing so on my own. I started with two awful

[Qgis-developer] SEXTANTE adaptation to new SAGA version

2013-07-04 Thread Victor Olaya
Hi all

SAGA 2.1.0 has just been released. The current version of SEXTANTE in
master has been now adapted to work with SAGA 2.1.0, and raster
algorithms will not work with any other version. Please, update your
SAGA executables if using the latest master version, since now 2.1.0
is the target version.

The only algorithm adapted so far is the raster export one, which, for
SEXTANTE, was the most important one that had been modified, since it
blocks all other raster algorithms. Other algorithms might have
changed, but they are not adapted yet. If you find something that was
working before and now it doesn't, please report. Also, if there are
new algorithms, feel free to suggest them to be added to SEXTANTE as
well, describing their syntax, if possible, to help us do it.

Windows users, please notice that the Osgeo4W installer still ships
with SAGA 2.0.8, so you will need to install SAGA 2.1.0 manually and
change the SAGA path in SEXTANTE. This will be updated soon, so it's
just a temporary issue

Thanks for your help

Hi,

I was under the impression that the GUI would be finalized with string
freeze. Is the plan now to incorporate these new icons in 2.0? I'm
asking because I'm preparing material which I would like to be
up-to-date with the final release and I would like to know when I can
be certain that the screenshots won't change anymore. Or should I wait
until the release is out?

Best wishes,

 for panToSelected, instead of rotating the hand you could try to just leave
 it like pan and add the selection box, that way it will eliminate the
 select by click effect I think

 Hi Denis,

 thanks for your effort.

 +1 for pan = hand
 panToSelected with hand looks like select by click to me, so +1 to
 keep current (symbols IMHO need not be similar as panToSelected is a
 button and pan is a tool)

Re: [Qgis-developer] new icons

Hi Anita!

Sorry for that .. but string freeze does not seem no necessarily mean
GUI Freeze :)
Anyway .. I also fixed some typos and bug in the original language that
i got reported back ..
And i think with this changes to some icons we should be good to leave
the GUI on its own ..

And .. well except of the hand (which I also like more than the arrows
for panning) The icons look at least very similar to what they looked
before ..

And my personal opinion is still that people should not rely that much
on how the icon look like but more on the function behind it ..

regards
Werner

[Qgis-developer] Building QGIS 1.8 in openSUSE 12.3

2013-07-04 Thread nik
Hi QGIS devs!

I recently switch (and still am in a testing phase) from (K)Ubuntu to openSUSE 
(12.3).  Feels great so far, stable -- very.

I am trying to  compile QGIS 1.8 from source but I have some difficulties as I 
am not sure how similar the process is comparing to (K)Ubuntu (Debian-based) 
Linux.


I think I have (already) installed build dependencies with

sudo zypper si -d qgis

Reading installed packages...
Loading repository data...
Resolving package dependencies...

Nothing to do.



Next, I have instructed in /etc/ld.so.conf.d/osgeo.conf

/osgeo/src/Quantum-GIS/build/output/lib/



The configuration (ccmake) goes fine and then, the compilation fails:

Linking CXX shared library ../../output/lib/libqgis_gui.so
[ 47%] Built target qgis_gui
make: *** [all] Error 2



The file mentioned above exists in

/osgeo/src/Quantum-GIS/build/output/lib/libqgis_gui.so



What is next to do/search in order to get qgis compiled?

Thanks, Nikos

Hi Anita,

I am sorry I started this without discussing more.
As said, I just wanted to do one or two, and I end up with doing 10.
I will do the last today, and I will pull request today. So then, it's 
just a matter of when the pull requests are accepted.
Also as said Werner, these are really minor changes except for the 
really bad ones (the next will be oracle and mssql).


Greetgins,

Denis

Hi,

I was under the impression that the GUI would be finalized with string
freeze. Is the plan now to incorporate these new icons in 2.0? I'm
asking because I'm preparing material which I would like to be
up-to-date with the final release and I would like to know when I can
be certain that the screenshots won't change anymore. Or should I wait
until the release is out?

Best wishes,
Anita
