I'm trying to convert an image file data from Python PIL to an unsigned char*. Here's how i read the image data from python: im = PIL.open( filename ) data = list( im.getdata() ) Now, i want this data in unsigned char* so that i can use it in my c++ codes for texture mapping, any help please?

Look for array in the python-docs

from array import array
import Image

im = Image.open("test.bmp" )
data = list( im.getdata() )

#here is your data as an array of unsigned char

#let's write it to a file
