Thanks. 
I have a .bil file with an associated .hdr file with metadata. Do I have to
read in the .hdr file and manually prepare the variables or is there a
specified function? I could not find much info. about .hdr file.
I am not sure what should the values be for pixel height and pixel width. I
am using a 16 bit resolution camera.
Can you advise me on what steps I need to undertake when creating a C prog
which would be inputted with a .bil file?

Sincerely,
Joseph
