Re: [Qgis-user] Can´t open Processing model

[johnrobot]

Hi
I tried View - Panels - Log Messages and in the Processing tab I found:

CRITICALCould not load model C:/Users/johnr/Desktop/Subnet Areas.model3

Not much help, I´m afraid. However, I downloaded the model3 file again, and
now it opens just fine. Sorry for the noise.

Magnus

[QGIS-it-user] Integrare SAGA 7.x in processing

[Stefano Campus]

ciao a tutti,
come ben sapete data la pessima abitudine degli sviluppatori di SAGA di
cambiare senza preavviso, al momento la versione standard di SAGA supportata
in Processing è la versione ltr 2.3.
Tuttavia nel corso degli ultimi mesi ci sono vari tentativi di integrare in
processing anche le ultime versioni di saga 7.x.
attraverso un plugin di alexander bruy, non più presente nel suo repository
[1] (c'è comunque il plugin per utilizzare in Processing gli altrettanto
validi moduli di Whitebox GIS) ed ora un plugin di northroad sul repo
ufficiale (Processing Saga NextGen Provider), è possibile, appunto,
utilizzare le ultime versioni di SAGA.

oggi invece scaricando la versione GUI di SAGA per windows nel repo di
Sourceforge [2] ho scoperto che pare che direttamente si possa utilizzare
SAGA in Processing senza plugin terzi.

purtroppo, come spesso succede per la documentazione di SAGA non ho mica
capito quale sia la procedura sinteticamente illustrata nel readme.txt.

chiedo dunque a qualcuno se può cortesemente dare un'occhiata al contenuto
del file saga4qgis.zip contenuto nel pacchetto [2] e mi può dare una propria
interpretazione della procedura. 

grazie mille

s.

[Qgis-user] Can´t open Processing model

[johnrobot]

Hi
I´m trying to open a .model3 file, downloaded from
https://github.com/mattmarotta/QGIS-Subnet-Areas. When opening it in
Processing, QGIS says "The selected model could not be loaded. See the log
for more information". Which log would that be? If I open Processing -
History..., the window only contains "ALGORITHM", no further information. It
would be helpful if QGIS could tell me why I can not open the model. Tried
on QGIS 3.16.0 64 bit, Windows 10.

Regards,

Magnus

Hi Chris thank you for the explanations.
Anyway I gave the output folder path so why it should save the output in
another location. Furthermore I searched in my PC but i don't find this
output. Anyway this command is well working in this new version Qgis 3.16
so for the moment I am ok.

Thanks again, Azzurra

Re: [Qgis-user] Problème de composeur / Print composer problem

[Andreas Neumann]

Hi Adelin,

Somehow you don't seem to have a page in your layout. Can you try in the
"Layout" menu --> "Add Pages" to add a page? Or create a new layout.

I don't know how you managed to remove the last page in a layout. I tried,
but couldn't ... or maybe it is some bug in QGIS. But it never occurred to
me that all pages have been removed.

Hope this helps,
Andreas

[Qgis-user] Delete a class from QgsPalettedRasterRenderer

[PIERRE Sylvain]

Hi List,
I want to remove some class from a QgsPalettedRasterRenderer in a python script.
I got the renderer and classes with :
renderer = myLayer.renderer()
clas = renderer.classes()
I can iterate classes, modify label and so on.
But I don’t find any tips to delete a class as I can do in the ui.

Any idea?

Thanks

Re: [Qgis-user] Has anyone experienced this problem?

[info]

  
  
Thanks Saber for your reply.
Unfortunately, none of the three Tile Resolution options solve
  this problem.
In fact this problem occurs with Google satellite(1) and OSM
  B(2) not the other XYZ tiles servers I'm using.
Thanks again,
  Benoit

1. Google satellite:
http://www.google.cn/maps/vt?lyrs=s@189=cn={x}={y}={z}
  2. OSM B: http://tiles.wmflabs.org/bw-mapnik/{z}/{x}/{y}.png

  Hi, 

  XYZ tiles do not display on 4K/HD dual screen on
  Win10

Setup: Win10Pro. Dual screen: main: 4K (true 3840x2160,
no scaling), secondary HD (1920x1080).
  
  Affected QGIS versions: 3.10 to latest dev
  
  Problem:
  XYZ tiles (e.g. Google satellite) do not display
correctly, if at all, when width of QGIS canvas is
  above 2000px. See 4kpb2.jpg.
  
  Is this a known feature/limitation of QGIS?
  One solution is to reduce the width of QGIS canvas
below 2000px but this looses the advantage of 4K screen.
See 4kpb1.jpg.

There is apparently no API for that, you could try to use

QgsPalettedRasterRenderer::classDataToString

modify the string and then call:
QgsPalettedRasterRenderer::classDataFromString



Kind regards.

[Qgis-user] Problème de composeur / Print composer problem

[adelin collette]

Bonjour,

J’ai un problème avec l’édition du composeur sous QGIS 3.4.15. Quand mon 
composeur d’impression s’ouvre, je n’ai accès à aucun bouton, ils sont tous 
grisés… (voir photo) Je ne peux donc rien faire…
Auriez-vous une idée pour régler le problème ?

Merci d’avance,

Adelin

Hello,

I have a problem with the composer edition under QGIS 3.4.15. When my print 
composer opens, I don't have access to any buttons, they are all greyed out ... 
(see photo) So I can't do anything ...
Do you have an idea to solve the problem?

Thank you in advance,

Adelin

[Qgis-user] Has anyone experienced this problem?

Hi, 
  
XYZ tiles do not display on 4K/HD dual screen on Win10
  
  Setup: Win10Pro. Dual screen: main: 4K (true 3840x2160, no
  scaling), secondary HD (1920x1080).

Affected QGIS versions: 3.10 to latest dev

Problem:
    XYZ tiles (e.g. Google satellite) do not display correctly, if
  at all, when width of QGIS canvas is above 2000px. See
  4kpb2.jpg.

Is this a known feature/limitation of QGIS?
One solution is to reduce the width of QGIS canvas below 2000px
  but this looses the advantage of 4K screen. See 4kpb1.jpg.
Regards,
Benoit
