<H2>DESCRIPTION</H2>
|
|

|
|
Produces a Microsoft Windows or OS/2 BMP file as output.

|
|
<H2>OPTIONS</H2>
|
|
|
|
<P>
|
|
|
|
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.
|
|
<DL COMPACT>
|
|
<DT id="1"><B>-windows</B>
|
|
|
|
<DD>
|
|
Tells the program to produce a Microsoft Windows BMP file.
|
|
(This is the default.)
|
|
<DT id="2"><B>-os2</B>
|
|
|
|
<DD>
|
|
Tells the program to produce an OS/2 BMP file.
|
|
(Before August 2000, this was the default).
|
|
<DT id="3"><B>-bpp</B>
|
|
|
|
<DD>
|
|
This determines how many bits per pixel you want the BMP file to contain.
|
|
Only 1, 4, 8, and 24 are possible. By default,
|
|
<B>ppmtobmp</B>
|
|
|
|
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,
|
|
<B>ppmtobmp</B>
|
|
|
|
tells you and terminates. You can use
|
|
<B>ppmquant</B>
|
|
|
|
or
|
|
<B>ppmdither</B>
|
|
|
|
to reduce the number of colors in the image.
|

|
|
<H2>NOTES</H2>
|
|
|
|
To get a faithful reproduction of the input image, the maxval of the
|
|
input image must be 255. If it is something else,
|
|
<B>ppmtobmp</B>
|
|
|
|
the colors in the BMP file may be slightly different from the colors
|
|
in the input.
|
|
<P>
|
|
Windows icons are not BMP files. Use
|
|
<B>ppmtowinicon</B>
|
|
|
|
to create those.
