This is the command rawtoppm that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
rawtoppm - convert raw RGB bytes into a portable pixmap
SYNOPSIS
rawtoppm [-headerskip N] [-rowskip N] [-rgb|-rbg|-grb |-gbr|-brg|-bgr ]
[-interpixel|-interrow] width height [imagedata]
DESCRIPTION
Reads raw RGB bytes as input. Produces a portable pixmap as output. The input file is
just RGB bytes. You have to specify the width and height on the command line, since the
program obviously can't get them from the file. The maxval is assumed to be 255. If the
resulting image is upside down, run it through pnmflip -tb .
OPTIONS
-headerskip
If the file has a header, you can use this flag to skip over it.
-rowskip
If there is padding at the ends of the rows, you can skip it with this flag.
-rgb -rbg -grb -gbr -brg -bgr
These flags let you specify alternate color orders. The default is -rgb.
-interpixel -interrow
These flags let you specify how the colors are interleaved. The default is
-interpixel, meaning interleaved by pixel. A byte of red, a byte of green, and a
byte of blue, or whatever color order you specified. -interrow means interleaved
by row - a row of red, a row of green, a row of blue, assuming standard rgb color
order. An -interplane flag - all the red pixels, then all the green, then all the
blue - would be an obvious extension, but is not implemented. You could get the
same effect by splitting the file into three parts (perhaps using dd), turning each
part into a PGM file with rawtopgm, and then combining them with rgb3toppm.
