Re: [QGIS-Developer] run algorithm pyQgis 3
Dear Matteo,
What version of QGIS are you running?

Re: [QGIS-Developer] run algorithm pyQgis 3
I get this:
>>> processing.algorithmHelp('saga:triangulation')
Triangulation (saga:triangulation)
Input parameters
SHAPES: Points
Parameter type: QgsProcessingParameterFeatureSource
Accepted data types:
- str: layer ID
- str: layer name
- str: layer source
- QgsProcessingFeatureSourceDefinition
- QgsProperty
- QgsVectorLayer
.
if you search for triangulation in the Processing toolbox do you find
the algorithm of SAGA?
Cheers

Re: [QGIS-Developer] run algorithm pyQgis 3
Dear Matteo,
Thank you for your answer.
I using this code to check all the processing available with PyQGIS3
> for i in QgsApplication.processingRegistry().algorithms():
> print("{}:{} --> {}".format(i.provider().name(), i.name(),
> i.displayName()))
In the result there is no "saga:triangulation".
Also, I already try algorithmHelp('saga:triangulation')
[image: image.png]
There is no result.
That is the reason why I am writing here. I search for several days and I
do not find anything, also in StackOverflow and StackEchange.
Thank you in advance!

check which parameters have been specified: it might be a different
number of them between QGIS2 and QGIS3.
Type processing.algorithmHelp('saga:triangulation') to see the list and
type of each single parameter.
A complete guide of how to use algorithm from the console is n the user
manual:
https://docs.qgis.org/testing/en/docs/user_manual/processing/console.html

[QGIS-Developer] run algorithm pyQgis 3
Dear Qgis people,
I am trying to convert a script from PyQGIS 2 to PyQGIS 3
In the original script, the author used
processing.runalgorithm("saga:triangulation", parameters). Now, I am trying
to use it as same as possible with PyQGIS3 but I am not finding anything
similar:
1. I am using processing.run instead of processing.runalgorithm
2. I am aware that there is no SAGA API for Python 3
3. The objective of the code is change as less as possible. That's why
I am not looking for other solutions (except if you tell me there is no
similar solution, of course)
Maybe someone knows what can I do in this case?
Thank you all in advance for your time reading my problems!
