Clip raster by mask layer returns error "wrong number of parameters"

Question

Using Python for QGIS 2.14 Essen i try to clip a raster by a Polygon, as indicated here: http://docs.qgis.org/2.6/de/docs/user_manual/processing_algs/gdalogr/gdal_extraction/cliprasterbymasklayer.html

with this code:

processing.runalg('gdalogr:cliprasterbymasklayer', input, mask, no_data,     alpha_band, keep_resolution, extra, output)

My code read as following:

processing.runalg('gdalogr:cliprasterbymasklayer', inputlayer, maskshape, "none", False, False, "", outputraster)

Exactly as derived from tutorials. However, this is the error message returned and I can't figure why: Error: Wrong number of parameters

I´ve adapted the code to the 16 parameters of the new version, although I´m not sure if correct

processing.runalg('gdalogr:cliprasterbymasklayer', inputlayer, maskshape, "", False, False, False, 0, 0, 0, 0, False, 0, False, "",  "outputraster")

The error message says still the same.

Answer 1

I think the following parameters requires a minimum value of 1:

• JPEGCOMPRESSION
• ZLEVEL
• PREDICTOR

The others can be set to 0 so you could try running the following which works for me:

processing.runalg('gdalogr:cliprasterbymasklayer', inputlayer, maskshape, "", False, False, False, 0, 0, 1, 1, 1, False, 0, False, "", "outputraster")

Answer 2

The solution above didn't work me with QGIS 2.18.20. Still not enough parameters although the documentation says something different.

My solution: Do it with the graphical modeler (Processing -> Graphical modeler) and than export it as python script.
