Re: [Qgis-user] [QGIS-Developer] Mac QGIS 3 GRASS fix

[William Kyngesburye]

Yes, that looks like the source of the problem.  The os.walk() finds the color 
file named "grass" before it has a chance to find the real "grass72" file at 
the top level of the grasspath.  Though this is odd since it looks like os.walk 
by default should return a folder's info before it walks subfolders.

I don't think a file check will help, since it finds a file from the returned 
files list.  I do think the walking the whole grasspath tree is excessive.

I believe it's this bug:

https://issues.qgis.org/issues/17555

The permission errors is caused because it's actually trying to
execute /Applications/QGIS3.app/Contents/MacOS/grass/etc/colors/grass
instead of the correct grass binary.

The bug is caused by this function:

https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Utils.py#L130

It's trying to automatically generate the grass executable path, but
it's incorrectly finding the colors/grass folder and deciding that
it's the grass executable. I think inserting a os.path.isfile check
somewhere around line 145 should fix this, but not having access to an
osx install I haven't been able to test this.

Hope that helps -- would be great to have this one sorted for 3.0.1 if
you can confirm a fix!

Re: [Qgis-user] Mac QGIS 3 GRASS fix

[William Kyngesburye]

Well, it seems that running any GRASS Processing coughs up this error.  Mystery 
to me, permissions are correct for the app, nothing should be writing to the 
app, and if it is trying that's wrong.

The error doesn't help me try to figure out what's going on.  Help would be 
appreciated.

[QGIS-it-user] Errore Clip Raster con poligono in file Geopack

[Luca Bellani]

Salva ho la seguente situazione:
1) raster DEM
2) poligono con forma di rettangolo in un file Geopack, nuovo, creato solo
per contenere questo poligono
3) se eseguo il Clip atraverso il progesso di saga "clip raster with
polygon" o con "il comando GDAL preso negli strumenti di processing, nessun
problema. (GDAL risulta enormenete piú veloce)

4) se eseguo il comando , come avevo sempre fatto, dal menu
raster-estrazione-clipp, da errore

sia nel punto 3 che 4 ho spuntato le stesse opzioni (creare canale alpha e
tagliare ai bordi)

Vi é mai successo?

What are you doing?  GRASS plugin tools or Processing GRASS algorithms?

Nothing should be trying to write to the GRASS dir.  There should not be 
permissions problem reading from the GRASS dir.

Ciao e grazie per la prova,
la cosa diventa ancora più interesante, su mac crea anche il pdf errato.
da me il pdf è perfetto, ma le immagini esportate come atlas no.

allego pdf:

Ciao Salvatore,
ho ripetuto sul mio MAC la creazione dell'atlante delle regioni così come da
te proposta.
Il risultato è questo:
1) sullo schermo le regioni appaiono in maniera corretta
2) sul pdf salvato le immagini verticali risultano tagliate e le immagini
orizzontali risultano corrette
3) sul jpg salvato le immagini verticali risultano tagliate e le immagini
orizzontali risultano corrette.
Non c'è differenza tra pdf salvato e jpg salvato.

[QGIS-it-user] QGIS 3 e l'esportazione in immagine di un atlas

[Totò]

Salve a tutti,
mentre scrivevo questo articolo [0] sul compositore di stampe di QGIS 3.0 mi
sono reso contro che esportando l'atlas in formato immagine., le immagini di
output hanno un errore strano sul formato, cosa che non accade se esportate
in PDF.

Nell'articolo spiego come realizzare un atlas e far variare il formato della
pagina (orizzontale, verticale) in funzione della geometria dell'atlas.

Esportando l'atlas come immagine le dimensioni della pagina non vengono
rispettate o meglio sono rispettate solo quelle in formato orizzontale,
quelle in verticali vengono dimezzate;
la cosa è parecchio strana perche se esporto in PDF il problema non si
verifica oppure se esporto singolarmente in immagini.

purtroppo dovete seguire il mio articolo per riprodurre il problema (oppure
scaricare i dati e progetto allegato all'articolo), 
se qualcuno ha voglia di testare e ben accetto altrimenti devo segnalare il
bug senza una prova in altri pc e configurazioni.

saluti

ciao Giuliano,
innanzitutto sono passato alla v. 2.18 ed fatto varie prove con diversi
plug-ins.
QNetwork ha un algoritmio denominato *calculate connectivity*: quello che
cercavo.
Fissato esclusivamente il punto origine, traccia il percorso verso il punto
estremo, evidenziando le varie linee che compongono il grafo.

Ti ringrazio per la disponibilità

[Qgis-user] Mac QGIS 3 GRASS fix

[William Kyngesburye]

The non-working GRASS in the Mac QGIS 3 should be fixed now.  It appears the 
GRASS internals still don't like spaces in the path to GRASS -- this came from 
my adding "3" to the QGIS app name with a space.  The app is now without a 
space, "QGIS3.app".

It looks like the missing SAGA is also fixed by the rebuild (don't know why, it 
just happened).

REMINDER: My QGIS 3 package requires the python.org Python 3.  Other 
distributions/installations of Python are not supported (ie Homebrew, Macports, 
Anaconda...).

Re: [QGIS-it-user] Problemi interrogazione shp con relazioni 1:N

[Martina Savarese]

Ho rifatto una prova con gli shp del sample data di QGIS (airports e
regions, entrambi shp)
e poi rifatta trasformando lo shp degli areoporti in csv e impostando
la relazione con esso

con QGIS 2.18.17 nessun problema nella relazione tra due shp, mentre
persiste il problema segnalato nella relazione tra shp e csv
con QGIS3 nessun problema in entrambi i casi (forse nel csv usato
precedentemente avevo troppi record collegati a ciascun elemento del
vettore?)

[QGIS-it-user] Problemi interrogazione shp con relazioni 1:N

[Martina Savarese]

Salve,
creando delle relazioni 1:N su degli shp (relativamente a csv con
molteplicità N) ho riscontrato problemi nell'interrogazione (finestra
"attributi elemento") degli shp una volta chiuso e riaperto il
progetto (che invece funzionava appena impostata la relazione), sia
con la 2.18.17(-3) che con la 3.0

Con la 2.18.17(-3):
funziona perfettamente con "genera maschera automaticamente", mentre
con "crea maschera d'inserimento" funziona finché non chiudo e riapro
il progetto. Una volta riaperto, nel modulo d'interrogazione la parte
della relazione (N) risulta vuota sia in modalità vista modulo che in
quella vista tabella (mentre sugli shp in cui la maschera è generata
automaticamente continuo a vederla)

Con la 3.0 (dal nuovo pannello "Attribute form") :
- con "genera automaticamente" la relazione non si vede
-con "crea maschera d'inserimento" ho due casi:
1) funziona sempre se creo una scheda e la lascio vuota; se invece
inserisco i campi dello shp nella scheda creata la parte della
relazione risulta vuota una volta chiuso e riaperto il progetto
2) se non inserisco alcuna scheda, l'interrogazione funziona funziona
finché non chiudo e riapro il progetto. Quando lo riapro interrogando
lo shp QGIS va in crash
L'unico modo che ho trovato per farlo funzionare,anche dopo la
riapertura, è inserire una scheda vuota, purché venga spostata al di
sopra della relazione nell'albero del "Form layout"

Ciao,
ho appena fatto un atlas e messo la scala grafica, tutto regolare.

l'errore è stato appena corretta da matteo Ghetta.

[QGIS-it-user] R: stampa Atlas

[Rancati Erica]

Buongiorno,
non ho mai scritto e non so se questa sia la modalità corretta per chiedere un 
aiuto, mi scuso anticipatamente se dovesse essere sbagliata.
Non riesco in alcuna maniera a stampare le schede relative ad un atlante. 
L'atlante è costruito su corpi idrici superficiali ed il layout prevede, oltre 
alla mappa, delle tabelle con informazioni (nome e codice del corpo idrico...) 
e dei campi in cui registrare a posteriori dei dati. In tutto sono 54 schede ma 
al momento di mandarle in stampa compare una finestra "sto disegnando le mappe" 
con l'indicazione della percentuale di avanzamento del lavoro ma al termine o 
stampa un'unica pagina bianca o stampa le prime 3 o 4 schede correttamente e le 
successive senza mappa. Ho provato anche a stamparle singolarmente ma il 
problema si ripropone.
Cosa sbaglio? Ho salvato ognuno dei singoli layer su pc (quindi non li deve 
"pescare" esternamente).
Grazie a chi mi illuminerà,

Erica

Buongiorno, in Qgis 3  ho realizzato un Atlas e inserito la scala in 
modalità numerica, come scorro l'Atlas la scala viene resettata a 1:1, 
capita anche a voi?


Inoltre in fase di stampa esce come scritta "Esportanto" invece di 
"Esportando".

Re: [Qgis-user] Using processing algorithms from the console in QGIS 3.0

Hi Håvard,

after you have run the algorithm

you can also display the results in the TOC as memory layer with:

param = {'INPUT': 'my_points', 'BUFFER': '0.0' ,'OUTPUT':'memory:'}
processing.runAndLoadResults('qgis:voronoipolygons', param)

Re: [Qgis-user] Using processing algorithms from the console in QGIS 3.0

[Havard Tveite]

QgsApplication.processingRegistry().algorithms() does not
list grass7:v.to.rast.value (but grass7:v.to.rast is
there).

In QGIS 3, the following seems to work:

myres = processing.run("qgis:union", {'INPUT': "my_input", 'OVERLAY': 
"my_overlay", 'OUTPUT': "my_result"}, feedback=None)['OUTPUT']


processing.algorithmHelp("qgis:union") describes the
parameters of the algorithm.
Parameter names are case sensitive (at least on Ubuntu).

Hello,

I'm trying to migrate some pyqgis code from 2.14 to 3.0 and discovering

Say I have this command, which worked in 2.x:

does not work as expected. In the PyCharm debugger, I receive this error

(If the command syntax is in fact correct, then perhaps the algorithm is 
not accessible?)


My questions:

  * Is there up-to-date console documentation for the Processing toolbox
somewhere?
  * How can I get a listing of the available algorithms in the same
format as in 2.x?
  * How do I convert the algorithm calls (processing.runalg) from 2.x to
3.x?

Re: [Qgis-user] Using processing algorithms from the console in QGIS 3.0

[Stefan Giese (WhereGroup)]

Hi Stephen,
I asked a similar question at gis.stackexchange.com 
(https://gis.stackexchange.com/questions/274144/passing-input-output-parameters-to-processing-scripts-using-qgis-3) 
and I think we have to be patient. The documentation is work in 
progress. I am sure processing tools will work like a charm, when we 
will know how to use it;-)
