> **TLDR:** Convert a PPM image to a BMP file.
>
- Convert a PPM image to a BMP file:
  `ppmtobmp {{path/to/file.ppm}} > {{path/to/file.bmp}}`
- Explicitly specify whether or not a Windows BMP file or an OS/2 BMP file should be created:
  `ppmtobmp -{{windows|os2}} {{path/to/file.ppm}} > {{path/to/file.bmp}}`
- Use a specific number of bits for each pixel:
  `ppmtobmp {{-b|-bbp}} {{1|4|8|24}} {{path/to/file.ppm}} > {{path/to/file.bmp}}`

## NAME
       ppmtobmp - convert a portable pixmap into a BMP file

## SYNOPSIS
       **ppmtobmp** [**-windows**] [**-os2**] [**-bpp=**_bits_per_pixel_] [_ppmfile_]

## DESCRIPTION
       Reads a portable pixmap as input.  Produces a Microsoft Windows or OS/2 BMP file as output.

## OPTIONS
       All  options can be abbreviated to their shortest unique prefix and you can use a double dash
       in place of the single dash, GNU-style.

### -windows
              Tells the program to produce a Microsoft Windows BMP file.  (This is the default.)

### -os2
              fault).

### -bpp
              8, and 24 are possible.  By default, **ppmtobmp** chooses the smallest number  with  which
              it can represent all the colors in the input image.  If you specify a number too small
              to represent all the colors in the input image, **ppmtobmp**  tells  you  and  terminates.
              You can use **ppmquant** or **ppmdither** to reduce the number of colors in the image.


## NOTES
       To get a faithful reproduction of the input image, the maxval of the input image must be 255.
       If it is something else, **ppmtobmp** the colors in the BMP file may be slightly  different  from
       the colors in the input.

       Windows icons are not BMP files.  Use **ppmtowinicon** to create those.
