Add Raster File to empty table of content in Arcmap Desktop

Question

Hello,

I am trying to add a raster file from my directory to my current mxd file, but with arcpy.mapping.AddLayer function seems only adding one band per file, is there a sign for me to add RGB composite automatically using arcpy? Thankyou for your help.

I would go with makerasterlayer.  perhaps it behaves differently than mapping's AddLayer

Thank you for your response Dan,

I did, but I am getting confused when making a layer file from table of content, because if I run it manually, the script will only adding 1 band instead of 3 composite band, so I need a trigger to make a layer.

Is it possible for me to making an automize script that will adding the raster layer of my directory file without any trigger?

Here is my code :

import arcpy, os, glob, pythonaddinsimport Tkinter as tkimport tkFileDialog as filedialog
mxd = arcpy.mapping.MapDocument("Current")mxd.author = "Me"mxd.save()
root=tk.Tk()root.withdraw()    folder_selected = filedialog.askdirectory()root.destroy
# mxd = arcpy.mapping.MapDocument("Current")df = arcpy.mapping.ListDataFrames(mxd)[0]
file_name=[]for file in os.listdir(folder_selected😞    if file.endswith(".tif"😞        file_name.append(file)
# arcpy.mapping.AddLayer(df, arcpy.mapping.Layer(os.path.join(folder_selected,file_name[0])))
for lyr in arcpy.mapping.ListLayers(mxd😞    lyr.saveACopy(file_name[0] + ".lyr")
source_layer = arcpy.mapping.Layer(os.path.join(folder_selected,(file_name[0] + ".lyr")))
count = 0
for file in os.listdir(folder_selected😞    if file.endswith(".tif"😞        name = file.split(".")[0]
        rasterPath = os.path.join(folder_selected,file)        update_layer = arcpy.mapping.Layer(rasterPath)        arcpy.mapping.UpdateLayer(df, update_layer, source_layer, True)        arcpy.mapping.AddLayer(df,update_layer,"BOTTOM")        count = count + 1
