- 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.
