Try gdal_calc

gdal_calc.py -A input.tif --A_band=1 -B input.tif --B_band=2 -C input.tif
--C_band=3 -D input.tif --D_band=4 --outfile=reclass.tif
--calc="(A==109)*(B==178)*(C==200)*(D==255) +
(A==138)*(B==193)*(C==212)*(D==255) + (A==161)*(B==205)*(C==220)*(D==255)"

This will set the 3 RGB values to 1 and rest all to 0.

Si Ivano, la finestra di dialogo si nascondeva in background a quella di

[Qgis-user] QGIS 3.10.1 Lost toolbox and tools

2019-12-27 Per discussione Nick Hopton

For the last few days QGIS has been starting without loading the Toolbox or
Vector and Raster tools. I get this Python warning:

traceback: File "", line 1, in 
  File "/usr/lib/python3/dist-packages/qgis/utils.py", line 359,

line 51, in __init__
  uic.loadUi(ui_path, self)
  File "/usr/lib/python3/dist-packages/PyQt5/uic/__init__.py",

Hi,
Yes, google “reclassify”. You can do it multiple ways.

Hi,
Is it possible via gdal_translate, or other gdal program, to binarize a tile?

I would like the colors RGB 59,89,95,255 & 60,89,96,255  change to white (color 
entry 0) and that the other colors 109,178,200,255; 138,193,212,255 & 
161,205,220,255 change to black (color entry 1)

I don't understand how to use the -b and / or -mask arguments in this code
l = 'gdal_translate -a_srs EPSG:4326 -a_ullr ' + ullr + f_in + f_out + '\n'

Thanks
