SYNOPSIS
bmptopnm [-verbose] [bmpfile]
DESCRIPTION
bmptopnm reads a Microsoft Windows or OS/2 BMP file as input and produces a PNM (Portable aNyMap) image as output. The output format (PBM, PGM, or PPM) depends on the input: grayscale images produce PGM, color images produce PPM, and monochrome images produce PBM.This is part of the Netpbm package of image manipulation utilities. Input can be from a file or standard input; output is to standard output.
PARAMETERS
-verbose
Print additional information about the input file.

CAVEATS
