I would like to solve a problem (Species atlas (how to automate to create on page for each species with QGIS)). To solve it by an other way, I would like to know if it is possible to make a sextante process, and at the end, call, or use the map composer, directly into the Models Builder? If yes, how to do it?

As far as i know: No
The Map composer is mainly build to be a user friendly click-and-point tool and it requires some sort of python script to automatically generate a map within the Processing modeller.
So you have 2 ways to proceed:

  • Ether write yourself a custom python script to be used in the modeller. For this you just have to alter the provided python-code from your other question.
  • In my opinion more straight forward is to write a simple R script that generates the maps for you. See an example how to port r-script to QGIS processing on my blog. You could for instance write sth. like this (quick and dirty):


r <- raster("raster path")
pol <- readOgr("polygon dir","polgygon name")

png("where to save.png")
