- NAME
- rawtopgm - convert raw grayscale bytes into a portable
- graymap
-
- SYNOPSIS
- rawtopgm [-headerskip N] [-rowskip N] width height
- [imagedata]
-
- DESCRIPTION
- Reads raw grayscale bytes as input. Produces a portable
- graymap as output. The input file is just grayscale 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. Note that rowskip can be a
- real number. Amazingly, I once had an image with 0.376
- bytes of padding per row. This turned out to be due to
- a file-transfer problem, but I was still able to read
- the image.
