I want to run the r.reclass tool in python on a raster layer to reclassify 1 value (and leave the rest the way they are).

Here is my best attempt so far, after trying to reference documentation and other examples. Here is my code:

import processing



input_raster = QgsRasterLayer('/Users/ep9k/Desktop/Key-LogEcovaluator/Rasters/AestheticMax.tif', 'raster')

output_raster = '/Users/ep9k/Desktop/OutputReclass.tif'

rules_file = '/Users/ep9k/Desktop/reclassrules.txt'





parameters = {'Input' : input_raster,

            'rules' : rules_file,

            'Output' : output_raster,

            'GRASS_REGION_PARAMETER' : '1277290, 1314314, -14004, 11845',   #this is the exent of my raster layer

            'GRASS_REGION_CELLSIZE_PARAMETER' : 0

            }



processing.runAndLoadResults('grass7:r.reclass', parameters)

I run the script and I don't get any errors, but nothing happens. No output, nothing is reclassified. I think I am missing something obvious here.

I get the help docs by running the following in the console:

processing.algorithmHelp("grass7:r.reclass")

I am confused by 2 of the input parameters. Specifically GRASS_RASTER_FORMAT_OPT and GRASS_RASTER_FORMAT_META. Are these required?

  It looks like you're using the older 2.x API under QGIS 3?
