Re: [Qgis-user] Export to SQL Server plugin

[Pedro Venâncio via Qgis-user]

Hi Rikesh,

As Andrea said, you need to installgdal-mssandmsodbcsqlfrom OSGeo4W (
https://github.com/PedroVenancio/export_to_sql_server/issues/2#issuecomment-1240675079)
or any other way, if you have used the standalone installer.

Best regards,
Pedro

[Qgis-user] Passing parameters to ArcGIS REST Server Connections

[Pedro Venâncio via Qgis-user]

Hi all,

I'm trying to load Sentinel-2 images from ESRI Living Atlas, and it works
just fine with the default rendering rule, using

https://sentinel.arcgis.com/arcgis/rest/services/Sentinel2/ImageServer

But to use another color composite, it needs an additional parameter
(renderingRule):

&renderingRule={"rasterFunction":"Color Infrared with DRA"}

to get something like this:

https://sentinel.arcgis.com/arcgis/rest/services/Sentinel2/ImageServer/exportImage?f=image&bandIds=&renderingRule=%7B%22rasterFunction%22%3A%22Color%20Infrared%20with%20DRA%22%7D&bbox=-836244.2018886498%2C4956831.174231473%2C-723346.715967%2C4997342.799222562&imageSR=102100&bboxSR=102100&size=1477%2C530&token=.
..

The problem is that the additional parameter cannot be passed to ArcGIS
REST Server Connection URL
https://sentinel.arcgis.com/arcgis/rest/services/Sentinel2/ImageServer?renderingRule={"rasterFunction":"Color
Infrared with DRA"}

because it always adds "/exportImage" to the end of the connection URL:

https://sentinel.arcgis.com/arcgis/rest/services/Sentinel2/ImageServer?renderingRule=%7B%22rasterFunction%22:%22Color
Infrared with DRA%22%7D/exportImage&bbox=...

Any hint to overcome this?

Thanks!

Best regards,
Pedro

[Qgis-user] Rendering layers from MSSQL Server fail

[Pedro Venâncio]

Hi all,

I don't have too much experience in MSSQL Server, but I've created some
views that get some points (GPS positions) and convert them to lines.

Everything works fine, MSSQL Server shows the geometries correctly.

When I load them in QGIS, some of the lines simply don't show up on canvas,
but they are listed in the attribute table.

If I convert the binary geometry column to WKT, and put the WKT of the
geometries that does not render in QuickWKT plugin, they are rendered fine.

If I select, in the attribute table, the records that does not render and
run Extract Selected Features, they export fine and all geometries show up
as expected.

I also have run the Check Validity and here is the interesting thing:

 1) Using the GEOS method, all geometries are classified as valid and all
of them render as expected. Invalid and error output layers are empty.

 2) Using the QGIS method, all geometries are classified as invalid and
stay in the Invalid output layer. However, they are all rendered! The
errors are of two types: 'segments 47 and 69 of line 0 intersect at
-7.27335, 40.5264' and 'line 1 contains 2 duplicate nodes starting at
vertex 13'.

So, those errors does not seem to be a reason to not render the geometries,
since they are rendered in another formats.

Any hint about what can be happening?

Thank you very much!

Best regards,
Pedro Venâncio

Re: [Qgis-user] clip raster by mask layer (gdalwarp with -cutline option) enormously bloats file size

[Pedro Venâncio]

Hi Karsten,

First you have to ensure that the output data type is also Byte:
-ot Byte

Second, your original raster must be some kind of compression. You can see
it with gdalinfo. So, you need to apply compression to the output file, for
instance with:

-co COMPRESS=DEFLATE -co PREDICTOR=2 -co ZLEVEL=9


Best regards,

Pedro Venâncio

Re: [Qgis-user] Isochrones

[Pedro Venâncio]

Hi,

Besides Ujaval suggestions, you have also:

- Hqgis, using Here API:
https://plugins.qgis.org/plugins/Hqgis/

- v.net.* algorithms from GRASS, inside Processing, if you have your own
network:
https://grass.osgeo.org/grass78/manuals/v.net.html
Some examples here (unfortunately only in Portuguese):

Re: [Qgis-user] Error in Zonal statistic ?

[Pedro Venâncio]

Hi Lene,

Can you share a sample dataset?

I think it can be possible if the pixels have all different values, and so,
Zonal Statistics choose the minimum value as minority and majority, but it
could choose any other value, because any pixel value can be considered the
less and most represented, as they are all different.

Best regards,
Pedro Venâncio

Re: [Qgis-user] [QGIS-Developer] Drill-down forms with multiple selections option

Hi Alexandre,

You are the man!

For the record, I leave the filter expression from Alexandre Neto, that
work like a charm:

eval(' "di" in' + replace(current_value(
'DISTRITOS'),array('{','}','"'),array('(',')','\'')))

Thank you very much Alex!

[Qgis-user] Drill-down forms with multiple selections option

[Pedro Venâncio]

Hi all,

I'm building a form with two fields of "Value Relation Widgets", one
depending on the other.

This works really well as explained here https://youtu.be/ipezh4KXrgo by
Alessandro, but I would like that both fields have the multiple selections
option.

Here is a sample project:
https://cld.pt/dl/download/db1a1787-0adc-4633-a0c9-356c41f269eb/drilldown_multiple.zip

In that project, I have two shapefiles (one configured without and another
configured with 'Allow multiple selections') and two csv files (Value
Relation sources).

So, without multiple selections option, I simply use
"di" = current_value( 'DISTRITOS')
as filter expression.

This does not work with multiple selections, because this option saves the
multiple values between braces: {Value1,Value2,...}.

So, how could I use the filter here, to have the second field filtered by
the options selected in the first field?

Thank you very much!

Best regards,
Pedro Venâncio

Re: [Qgis-user] Get SAGA running on Ubuntu?

[Pedro Venâncio]

Hi Bernd,

Same problem here.

There is another SAGA plugin that support SAGA 7.3:

https://plugins.bruy.me/processing-saga.html

But I have some issues with raster algorithms in 3.10:

https://github.com/alexbruy/processing-saga/issues/3

They should be fixed in master, as said by Alex, but not for 3.10.

Best regards,
Pedro

Re: [Qgis-user] Wrong result with Saga Raster calculator

[Pedro Venâncio]

Hi Eugenio,

I've opened a ticket in QGIS bug tracker, to try to identify the source of
the problem:

https://issues.qgis.org/issues/16646

Please see the recent findings and give your feedback there.

Thanks!

Best regards,

Re: [Qgis-user] Wrong result with Saga Raster calculator

[Pedro Venâncio]

Hi Eugenio,

I've created a sample processing model (attached), that works ok, except a
small error in the result (decimals).

For instance:

*Raster* *ID* *Pixel value*
Z_top_res a 1202,03510276
t_top_res b 53,6123428345
topo c1 -182,584899902
SAGA Result 1 c 15,1783676147
SAGA Result 2 d 31,9437332153 *Diff*
Expected Result 1
15,1783679504 0,00335741
Expected Result 2
31,974087 0,0303540069
*Formula*
1 ifelse(c1>0,-(0.0065*c1-16),(0.0045*c1+16))
2 ifelse(a<500,0,((b-c)/a)*1000)
Using SAGA GUI there is no error.

Could this be because of some roundings in the input / output? (I'm sending
for the developer's list also).

Thanks!

Best regards,
Pedro Venâncio

Re: [Qgis-user] Wrong result with Saga Raster calculator

[Pedro Venâncio]

Hi Eugenio,

The result with SAGA Raster Calculator seems ok here, on QGIS 2.18.9, SAGA
2.3.2, both from OSGeo4W64 (result attached).

Z_top_res.tif have values from 724.403 to 1423.553, and so, the first
condition is never true. Then, it always make ((b-c)/a)*1000, and the
result seems ok to me.

Re: [Qgis-user] DWG import

[Pedro Venâncio]

Hi,

With this Randal's question, I've found something that can be a bug. When I
import the DWG, I can edit the layers created in the geopackage. Then, if I
save the group as Layer Definition File (to preserve the style and
symbology), close QGIS, and then add the QLR with Layer -> Add from Layer
Definition File..., the edit mode (Toggle Editing button) is disabled.

Anyone confirm?

I've tested the same process (save and open as Layer Definition File) with
other layers, and the edit mode works ok.

Thanks.

Best regards,
Pedro Venâncio

Re: [Qgis-user] Connecting QGIS to an Android GPS

[Pedro Venâncio]

Hi Paolo,

I've no problem to connect an Android phone (Nexus 4) to a Linux Mint /
Ubuntu laptop, both with ShareGPS [0] or GPS over BT [1] apps.

For instance, for ShareGPS, Add a new connection, Type standard NMEA
format, connection over bluetooth, auto find and connect to the laptop
bluetooth. Then click on 'bluetooth icon' on ShareGPS, to make the
smartphone visible to others by 180 seconds, and on laptop (where I've gpsd
deamon running), the steps are exactly the ones pointed by Richard:

$ hcitool scan
(here you will get the MAC address - xx:xx:xx:xx:xx:xx)


$ sdptool records xx:xx:xx:xx:xx:xx

In your case the answer is:

Service Name: ShareGPS
Service RecHandle: 0x10011
Service Class ID List:
  "Serial Port" (0x1101)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
Channel: 2

So, you do:

$ sudo rfcomm bind 0 xx:xx:xx:xx:xx:xx 2

and you will get the /dev/rfcomm0.

Then run QGIS with root, and connect GPS to /dev/rfcomm0.

It is working fine here.

Best regards,
Pedro Venâncio

Re: [Qgis-user] Fwd: different buffer distance for each side

[Pedro Venâncio]

Hi Azzurra,

Are you sure that you aren't using Offset Curve (ST_OffsetCurve) operation,
instead of Singe Side Buffer (ST_SingleSidedBuffer) operation?

By the way, Offset Curve operation is broken in QGIS 2.18.x. If you want,
you can overwrite
../python/plugins/processing/algs/gdal/ogr2ogronesidebuffer.py file by the
one attached to this email.

This problem was already fixed in master by Alexander Bruy, using a
different approach than mine, spliting the operations. I think this change
should be backported Alexander, what you think? Or should I make a pull
request to QGIS 2.18.x with this change on ogr2ogronesidebuffer?

Best regards,
Pedro Venâncio

Re: [Qgis-user] Struggling with datum transformations and grid shift files

[Pedro Venâncio]

Hi Andreas,

Some time ago, I wrote a text (in the QGIS portuguese user group blog)
about the use of coordinate transformations and NTv2 grids in QGIS. It's in
portuguese, but maybe google translator can help you get the idea. I hope
it helps.

Hi Lene,

But note that if you have created modules or scripts, they can become

For editing, we have in QGIS master the new Node editor widget [0], which

I don't know if you can work with Degrees, Minutes and Seconds in any of
them, but with decimal degrees they work well.

Re: [Qgis-user] raster calculator - no file produced

[Pedro Venâncio]

I also get this error message

Warning: QFileInfo :: AbsolutePath: Constructed with empty filename

when I double click in the "Raster band" to add the raster to "Raster
calculator expression".

After that, I don't get any other error, but I also don't get any result.

Re: [Qgis-user] raster calculator - no file produced

[Pedro Venâncio]

Hi Claas and Jurgen,

I just tested with a simple expression

"dem_srtm_pttm06_80m@1" * 2

and I can confirm that there is no result, both on 2.8 and 2.9 (master).

Same expression, on the same machine (Xubuntu 12.04 32bits), with QGIS 2.4
and 2.6, Raster calculator works as expected.

Re: [Qgis-user] [Qgis-developer] Transformation using NTv2 grids

[Pedro Venâncio]

Hi Bernd,

Here [0] we have an explanation of how the coordinate systems works in
general, and in particular in QGIS. You also find solutions to use the NTv2
grids with QGIS. Unfortunately, the text is in portuguese, but perhaps
Google Translate can help [1].

This is a way that each user must do individually. To make life easier for
portuguese users, as we also have a lot of information that needs to be
transformed to ETRS89, portuguese QGIS User Group developed the plugin that
Giovanni told you [2], which greatly simplifies things, because it is
integrated into Processing Toolbox and already provides the NTv2 grids.

As Giovanni said, if there is interest from other countries and if we can
freely redistribute the NTv2 grids, we can expand the plugin.


Best regards,
Pedro Venâncio

Re: [Qgis-user] Lizmap - can't insert&update data in PostGis Views

[Pedro Venâncio]

I do not know Lizmap, but I refer to the PostgreSQL user that Lizmap are
using to access the database (not the Lizmap user). This user is the same
that you are using in QGIS to access the database? This is because
PostgreSQL user must have permissions to run the triggers.

Re: [Qgis-user] How to set posgis default sequential value in a QGIS "editable" view?

[Pedro Venâncio]

Olá Alexandre!

If the gid field is serial, you can not just omit it in the Rule - Insert Into 
statement?

CREATE OR REPLACE RULE "_INSERT" AS ON INSERT TO "PGHP".infra_portoes DO INSTEAD
INSERT INTO "PGHP"."infraestruturas_pontos" ("classe","nome","geom")
VALUES ('portoes',NEW."nome",NEW."geom");

That way, Postgresql follows the sequence smoothly. 

Or I did not realize the problem right?

Pedro Venâncio

[Qgis-user] Set Drag and Drop Forms windows size on QGIS 2.0

[Pedro Venâncio]

Hi,

I know that in QGIS 2.0 it is possible to define the window size of custom 
forms in the designer, and QGIS will respect that. 

But is there any way to set the form size, in the case of drag and drop forms? 
Every time the form opens, returns to the default (width/height) window size.

Thanks!

Re: [Qgis-user] SAGA GIS dependency problem

[Pedro Venâncio]

Hi Matteo,

The problem is that ubuntugis-unstable provides GDAL 1.10, which has changes in 
libgdal package. Until GDAL 1.9.x, this package was called libgdal1. Starting 
from GDAL 1.10.x, this package became libgdal1h. 

Most likely, SAGA 2.0.8 that is in ubuntugis-unstable was compiled with GDAL 
1.9.x, taking libgdal1 as dependency. And Johan PPA should be under the same 
conditions.

Thus, there are two alternatives. Or downgrading to GDAL 1.9.x (for example, 
with ubuntugis-stable PPA), or we have to wait for someone to compile SAGA with 
GDAL 1.10.x.

I'm afraid this repository doesn't solve the problem. The dependency

[Qgis-user] SEXTANTE modules with a non-administrator user on windows

[Pedro Venâncio]

Hi,

I installed QGIS master in windows 7 with OSGeo4W, but I am having problems 
trying to run SEXTANTE GRASS and SAGA modules, when I use a user without 
administrative privileges.

If I "run as administrator", it works fine, but if I run with a normal user, 
all GRASS and SAGA modules gives this error:

Missing dependency.This algorithm cannot be run :-(
This algorithm requires GRASS to be run.Unfortunately, it seems that GRASS is 
not installed in your system, or it is not correctly configured to be used from 
QGIS
Click here to know more about how to install and configure GRASS to be used 
with SEXTANTE

Just doing "run as administrator" and using an admin user and everything works 
fine.

In SEXTANTE logs does not appear any more information.

Initially I did the installation with an administrator account, but I 
uninstalled everything (including deleted OSGeo and QGIS entries in the 
registry), reinstalled with a non-administrator user, but the same happens.

Does anyone have any idea about what may be happening? Apparently this only 
happens with SEXTANTE GRASS and SAGA tools.


Thanks!

Pedro Venâncio

Re: [Qgis-user] Qgis 2.0, Sextante and Saga GIS

[Pedro Venâncio]

Hi Filipe,

I asked Jerome Larouche (UbuntuGIS) to update the SAGA package in UbuntuGIS 
during his GSoC, and he already put this task in the schedule:

"Suggestions (Improvement for UbuntuGIS):

  * Make a new SAGA package."



Pedro



From: Filipe Dias 

Hi
Have the developers reached a decision on which SAGA GIS version should Linux 
(Ubuntu) users use in Sextante? 

SAGA 2.10 still causes problems in Sextante and SAGA 2.8 is not available in 
any repo for Ubuntu users
Regards
F.

Re: [Qgis-user] sextante & saga

[Pedro Venâncio]

I also agree, and continues to make me some confusion having different versions 
of SAGA in the SEXTANTE background.



Best regards,
Pedro

Re: [Qgis-user] sextante & saga

[Pedro Venâncio]

Hi Victor,

So the decision to use saga 2.0.8 on Linux is already definite? Because in this 
ticket http://hub.qgis.org/issues/8301 it was placed the issue of 
interoperability of models and scripts between SO.



Best regards,
Pedro

Matteo,on linux, SEXTANTE uses 2.0.8, not 2.1. This has been discussed
here in the list, and in IRC, and it seems that it is a bit soon to
force users to change to 2.1, since it uses a development version of
wxWidgets

[Qgis-user] Keep the scale fixed on the print composer

[Pedro Venâncio]

Hi,

Is it possible to define and maintain fixed the map scale on the print 
composer? Typically, we add the map (composer map) and when we increases or 
decreases the size of the map, the scale is updated/changed. Is there a way to 
do the opposite, that is, set the scale and when increasing or decreasing the 
composer map, the scale remains fixed and only change the bbox visible?

Thanks!

Pedro

[Qgis-user] Topology checker red markers

[Pedro Venâncio]

Hi,

I have a problem with the topology checker that I had already reported in this 
ticket http://hub.qgis.org/issues/8095.

However, I continue with the following problem. If I click on some of the 
errors in the list, when I make "New project", the last error that was clicked, 
do not disappear. All other disappear as expected. 

The last clicked only disappears if I click 'Validate all' again.

Please see the screencast: http://goo.gl/9fIJV


Apparently this problem does not happen with everyone, and may even be a local 
problem. Can someone test to see if it is necessary to open a new ticket?


Thank you very much!

Re: [Qgis-user] [Qgis-developer] Another compiling error at 48 percent

[Pedro Venâncio]

Hi Matthias,

Thank you for the tip, but this problem was simply lack of space in the virtual 
machine. My fault, sorry...


Hi Jürgen,

I was using the -d option because initially it was always rising errors with 
some libreoffice packages, and I did not remember to remove it at this time. 
The truth is that I was having some problems and conflicts with some 
dependencies: grass-dev, qgis-dev and python-central.

And sorry for the crossposting, I initially thought it was a general error, and 
sent to the devs list, but there was no answer, and tried in the users list. 
After all, it seems that it is a local problem, although it occurs on multiple 
machines. I leave here the record for those who are faced with the same 
problems.

Thank you and sorry for the noise.

Best regards,
Pedro

Hi Etienne,

You were right, I created a symlink to the file /usr/lib/libpython2.7.so

ln -sf /usr/lib/libpython2.7.so /usr/lib/i386-linux-gnu/libpython2.7.so

and it passed that stage.

But stopped again almost at the end:

Re: [Qgis-user] Another compiling error at 48 percent

[Pedro Venâncio]

Hi Etienne,

Thank you very much for your help!

I usually do not compile directly, I use the alternative of creating .deb 
packages with dpkg-buildpackage -us -uc -b -d -j4

In fact, it can be a local problem, maybe with some update, because it began to 
happen in the past weekend.

To test, I did a clean install on a virtual machine and it passes the 48%, even 
after applying all updates, but gives error at 83%...

Re: [Qgis-user] Volume between two surfaces

[Pedro Venâncio]

Hi Stefano,

What a great plugin [0]! As a geologist, I do not know how I had not noticed 
this plugin yet... 

Although for the the present case I can not take great advantage of it, I 
predict that it can be very useful on other occasions!

Thank you very much!


Best regards,
Pedro Venâncio

hi, maybe this plugin can help you

qgSurf: a Python program for the interactive determination of intersections
between DEM and planes

http://www.malg.eu/gsurf_en.php

in a slope stability analysis this information is essential; so it could be
very useful to calculate a volume having as input the dip and dip direction
of planes that isolate a rock volume.

Re: [Qgis-user] Volume between two surfaces

[Pedro Venâncio]

Hi Carlos,

Thank you for your great tip!

I was thinking... creating masks to separate the negative valuesfrom the 
positive values​​of the raster 'Hight', I can get the excavation and landfill 
volumes, right?


Thanks!
Pedro

Subject: Re: [Qgis-user] Volume between two surfaces

One idea:

Use calculator on GRASS and do:

Surface 1 - Surface 2 = Hight

We have the heigth value on each cell, so now use r.sum:

Volume = r.sum (of Hight) * side of pixel ^2 (if cells are squares)

Of course, you must use a mask to boundary your area of interest

[Qgis-user] Volume between two surfaces

[Pedro Venâncio]

Hi all,

Is there any way to calculate the volume between two surfaces (two DEM rasters)?

There are ways to calculate the volume between a surface and a particular 
height value (GRASS r.volume or SAGA Grid Volume) but I can not find how to 
calculate the volumes (landfill / excavation) between two DEM.

Any tips?

Thank you very much!

Re: [Qgis-user] Composer and transparency

[Pedro Venâncio]

Hi Cascafico,

I have also a problem with Composer on QGIS 1.8. When I use rasters with 
transparency along with other layers, some horizontal stripes appear without 
transparency.

Normally I make the union of MDT with Shaded Relief. To combine the MDT with 
the Shaded Relief, I use the r.his function, placing the MDT as HUE and Shaded 
Relief as Intensity, resulting in a set of three rasters corresponding to the 
three RGB channels. Then I use r.composite to create the final RGB image.


Best regards,
Pedro Venâncio

Hello valuable list!
Qgis composer has a known bug in managing raster layers with  transparency.
So I need a workaround to merge rgb relief with single band DEM.
Is there a pret-a-porter expression for raster calculator?
Or I need to convert rgb to hsv before? If so,  how?

Re: [Qgis-user] Sextante - problems with GRASS tools

[Pedro Venâncio]

Windows was also affected.

After this fix, the problems were solved (at least on QGIS master from OSGeo4W).

But I confess I do not know how the fixes have been applied to the stable 
version (1.8).

Re: [Qgis-user] [Qgis-developer] Strange integer column value within SpatiaLite database

[Pedro Venâncio]

Hi,


If I understand the manual http://www.sqlite.org/datatype3.html in section 2.2, 
sqlite/spatialite will consider all INT, INTEGER, TINYINT, SMALLINT, MEDIUMINT, 
BIGINT, UNSIGNED BIG INT, INT2 and INT8 types, simply as INTEGER. Hence, he 
considers the value 9100100101 correctly.

If the datasource supports datatypes with a length greater than the "normal" 
INT, then QGIS should show this fields correctly, right?

So, there is some way to "force" QGIS to properly handle with these INTEGERS 
from spatialite databases? 



Should I fill a ticket?

Thanks!
Pedro

Hi,

the same thing happens here. Using Sqliteman the value looks OK but when
using QGis Attribute table it turns into the strange value.

Is suspected it had to do with an int (32) conversion and so made a
small C test to confirm. If you run the C test in the linked ZIP you'll
get the following result when trying to pass 9100100101 as an integer:
(Sorry it's in Portuguese but it asks for an integer number and then
prints it)

Digite um número: 9100100101
O int é 510165509

I've also made another test in python to read the table, but python
automatically uses long when the value is unsuitable for int. That was
the result I got: the value looks OK but it's type is long, not integer.

In the link: the C test, the python test and the error print.

Tests: http://ubuntuone.com/4eQMOLf4KvlAbYHKxkqBIY

Cheers,
Rui.

Re: [Qgis-user] Sextante - problems with GRASS tools

[Pedro Venâncio]

Hi Victor,

I do not know, I've been working well during the last week with Sextante GRASS 
tools and only now noticed this issue. I applied the updates released through 
ubuntugis unstable, as usual.

I'll wait for the new update and see if it gets resolved. Then I will give 
feedback.

Thank you very much!

Best regards,

Working here for me.  There's been a change a week ago, modifying how
the grass mapset is created, but it seems you are not using it, since
it refers to the "user" mapset, and now everything goes into
PERMANENT. Maybe an old version somewhere?

[Qgis-user] Strange integer column value within SpatiaLite database

[Pedro Venâncio]

Hi,

I found something strange with data in a table within a SpatiaLite database.

As you can see in this image [1], viewing the table in QSpatiaLite, the column 
GEO_COD (integer) appears well. The same column, when viewed in the QGIS 
attribute table, appears with values ​totally different.

Can anyone find an explanation?

I leave the database in question in order to test [2].

I'm using QGIS master on Xubuntu 12.04.

Pedro Venâncio

[Qgis-user] Change transparency with new symbology - segmentation fault

[Pedro Venâncio]

I found a problem to assign transparency to a vector layer, using the new 
symbology -> Graduated style. When I do 'Change transparency', I get a 
segmentation fault (core dumped).

Anyone confirm? 

To replicate, simply add a vector layer, apply a Graduated symbology with the 
new symbology engine; then click with the right mouse button over the classes 
-> Change transparency.

I tried with spatialite and shapefiles, both with the same results 
(segmentation fault).

I am using QGIS master (ubuntugis) on Xubuntu 12.04.


Thanks.

Hi Régis,

I did here some tests with your data, your project and your composer 
(project_qgismaster_2613cf6.qgs).

I did exports to pdf vector up to 1200dpi (the generated pdf got 99.1MB) 
without any problems (nor tiling, nor crashes).

Regarding the export to pdf raster, everything worked well up to 500dpi (the 
generated pdf got 21.1MB). The three times I tried with 600dpi, qgis crashed.

I'm with QGIS master on Xubuntu 12.04, on a 6 years old laptop (Intel Core2 
T5500@1.66GHz CPU and 2x1GB DDR2@533 SDRAM).

The processor was several times at 100% and RAM in export to pdf raster was 
also close to 100%.

Hi All,
I tried to create a common environnement to help us test and reproduce
thoses crashes. 
Please find a zip  (220Mo) with datas and qgs projects here, complete test
report and screen captures of CPU/Memory state:
https://www.dropbox.com/sh/zg4zidwab83ym0d/VpxPA3euLI/QGIS_CRASH_COMPOSER
<https://www.dropbox.com/sh/zg4zidwab83ym0d/VpxPA3euLI/QGIS_CRASH_COMPOSER>  

here are my firsts conclusions:

- Making a fresh install of latest master with no plugin or setting *do not
often lead to crash (once only for 20-30 exports), since when pdf or image
raster if resolution is > 300 dpi, then printing just.. does nothing except
creating an empty pdf.* 
Two months ago, I had QGis computing several minutes and leading to a crash.
*Something has changed! No crash, but still no usable export *

- PDF Vector export has a 'tiling' issue of raster background. It seems to
consume less ressources than raster printing. 

- image export do warn user if memory usage is high. PDF export should do
the same. BUT, image export warns you, and does nothing.. just like pdf
export. no image is generated 


I would be pleased to have some feedbacks on your platforms and versions..
We reallly need to consolidate exports. Mapping in QGIS is really often
dedicated to export and printing.. We need it stable.

Hi,

This was an old thread, but this question came to me now. It's possible to 
apply transparency to the layer's labels?

The transparency that is applied to the layer is not 'replicated' in its label 
and I can not find a way to apply transparency to the labels (on QGIS 1.8).


Thank you very much!

It's the same, the plugin can not create the profile for the last segment of a 
polyline (if the polyline has only one segment, then it creates nothing).

Should I fill the tickets in http://hub.qgis.org/projects/profiletool/issues ?

I think this is due to major differences between 1.0 and 1.1 - I'll
try to look into this and probably just disable the matplotlib version
unless it's 1.0.
Unless someone has a fix for this...

Does this happen just with a 2-point polyline (when initially
created)? How about if you first create (and save) a 3-point polyline
before using the plugin?

Please file another bug report for this issue.

Re: [Qgis-user] Problem installing Profile plugin

[Pedro Venâncio]

Hi Etienne,

I'm also having some problems with the Profile Plugin. I'm using Linux 
(Xubuntu) and QGIS master.

The first problem is this with matplotlib (I'm also using matplotlib 1.1.1~rc1):

Traceback (most recent call last):
  File "/home/pedro/.qgis//python/plugins/profiletool/profileplugin.py", line 
278, in changePlotLibrary
    self.wdg.addPlotWidget(self.plotlibrary)
  File "/home/pedro/.qgis//python/plugins/profiletool/ui/ui_ptdockwidget.py", 
line 143, in addPlotWidget
    self.plotWdg = PlottingTool().changePlotWidget("Matplotlib", 
self.frame_for_plot)
  File "/home/pedro/.qgis//python/plugins/profiletool/tools/plottingtool.py", 
line 82, in changePlotWidget
    fig = Figure( (1.0, 1.0), linewidth=0.0, subplotpars = 
figure.SubplotParams(left=0, bottom=0, right=1, top=1, wspace=0, hspace=0) )
NameError: global name 'figure' is not defined


Using Qwt5 it works, but with some problems.

On one hand, if I close the Profile Plugin before closing QGIS, the button in 
Plugins toolbar remains "clicked", and when closing QGIS, it shows this error:

Error while unloading plugin profiletool
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 237, in 
unloadPlugin
    plugins[packageName].unload()
  File "/home/pedro/.qgis//python/plugins/profiletool/profileplugin.py", line 
80, in unload
    self.wdg.close()
RuntimeError: underlying C/C++ object has been deleted



In use, the Plugin displays a strange behavior.
Using the Selection "Temporary polyline" option, everything works fine.
However, with the Selection "Selected polyline" option, if the polyline has 
only 2 points (start and end), it does not create the profile. If I add another 
point, the Plugin only creates the profile for the first segment. If I create a 
fourth point, it just creates a profile for the first and second segments. And 
so on.

I leave a screencast showing these problems: http://goo.gl/0tMwk 



Thanks!

Best regards,
Pedro Venâncio

matplotlib 1.1.1. I used the Kyngchaos installer. 

Thanks for your work on this. An essential tool for my work.

Re: [Qgis-user] How to reproject vectors with Sextante?

[Pedro Venâncio]

Hi, 


I confirm Anita's observations.

Reproject Layer is now working well on Modeler, the resulting shapefile is well 
reprojected, but is added to the project with the project CRS.

Best regards,
Pedro

Hi,

Reprojection works now. Thank you!

The only issue is that - while the layer is correctly reprojected - it
is added to the project with wrong CRS settings. (Seems like project
CRS is picked no matter what was picked as a target CRS.)

Best wishes,

Anita

Hi,

Modeler is working again! At least with the little testing I've done, it's 
working well!

But Reproject Layer is still giving an error in Modeler:

Re: [Qgis-user] How to reproject vectors with Sextante?

[Pedro Venâncio]

Hi Alexander,

Thank you!! 

I already have the file corrected
https://raw.github.com/qgis/Quantum-GIS/master/python/plugins/sextante/modeler/ModelerParametersDialog.py

Is there any easy way to test it directly, as was the case before the sextant 
was placed as core plugin?

Thanks!

Oops, I think the error is from Modeler, because it is happening with every 
tool.

Anyone confirm?

Thanks. So, revison is dd67935. Reproject tool was added after
this commit.

In another thread Jürgen said that there were problems with
nightly builds, and as result latest changes still not available.
As I understand now this is fixed and next build will include
it.
