Convert jpg raster format to tif format

Question

I have 120 rasters( jpg format ) and i want to convert them to tiff format to folder called "OtherFormat" in env.workspace with arcpy. In my code i try to convert all jpg file I read http://resources.arcgis.com/en/help/main/10.2/index.html#//001200000032000000 and understand that i can do it if i will write the exact name of the raster. But i have 120 rasters so i tried to use asterisk:

import arcpy,os,sys,string
import arcpy.mapping
from arcpy import env

env.workspace = r"C:\Project\out"
arcpy.RasterToOtherFormat_conversion("*.jpg","OtherFormat","TIFF") 
print 'converted'

but get en error:

ExecuteError: Failed to execute. Parameters are not valid.  
ERROR 000732: Input Rasters: Dataset *.jpg does not exist or is not supported Failed to execute (RasterToOtherFormat). 

Answer 1

You need to make a list of the jpeg's and the n loop trough them. You can use the glob module for that:

import arcpy, os , glob

outworkspace = r"C:\Project\out\OtherFormat"
listOfJPG = glob.glob( r"C:\Project\out\*.jpg")

arcpy.RasterToOtherFormat_conversion(listOfJPG , outworkspace ,"TIFF") 

print 'converted'

Answer 2

You should iterate through each file in your directory and call the function on each filename:

import os
in_direc  = 'C:\raster_loc'
out_direc = 'C:\converted'
for file in os.listdir(in_direc):
    #check to make sure it's a jpg
    if 'jpg' in file:
        #you need to change the parameters of this function call accordingly
        arcpy.RasterToOtherFormat_conversion(file,"OtherFormat","TIFF")
