A simple python script to convert a raw binary coded image into a bitmap file. (applying metadata to a header)

raw2bmp.py

import struct

# Filenames
IFILE = "raw.bsq"
OFILE = IFILE + ".bmp"

# Image dimensions
NX = 512
NY = 2000

# Bitmap header
BMP_ID      = "BM"
SIZE_HDR    = 14
SIZE_DIB    = 40
CHANNELS    = 1
PLANES      = 1
BPC         = 16                # Bits per component
BPP         = CHANNELS*BPC      # Bits per pixel
OFFSET      = SIZE_HDR+SIZE_DIB
SIZE_IMG    = NX*NY*BPP
SIZE_FIL    = OFFSET+SIZE_IMG

head = BMP_ID + struct.pack('IHHIIIIHHIIIIII',\
    SIZE_FIL,0,0,OFFSET,SIZE_DIB,NX,NY,PLANES,BPP,0,SIZE_IMG,0,0,0,0)

data = open(IFILE,"rb").read();

open(OFILE,"wb").write(head + data)
