arcpy.ia.Colormap is not working on the .tif file or cannot be save by save method.

Hi team,

I'm trying to use arcpy.ia.Colormap function to change the color of Tiff file that is reclassified by arply.sas.Reclassify function.

After I execute the function, it doesn't show the error but when I tried to save by save method of Raster object, it gives an error back.

recolored.save(save_path)
RuntimeError: Unspecified error

but when I use the code below to the Tiff dataset, it can be recolored with no errors.

arcpy.management.AddColormap(save_path, "#", colormap)

I have attached Tiff image as zip file that supposed to be pointed at save_path

did you try

Copy Raster (Data Management)—ArcGIS Pro | Documentation

and experiment with the Colormap to RGB parameter
