- NAME
- pnmtops - convert portable anymap to PostScript
-
- SYNOPSIS
- pnmtops [-rle|-runlength] [-scale s] [-dpi n] [-width n] [-
- height n] [pnmfile]
-
- DESCRIPTION
- Reads a portable anymap as input. Produces Encapsulated
- PostScript as output.
-
- If the input file is in color (PPM), a color PostScript file
- gets written. Some PostScript interpreters can't handle
- color PostScript. If you have one of these you will need to
- run your image through ppmtopgm first.
-
- Note that there is no pstopnm tool - this transformation is
- one-way, because a pstopnm tool would be a full-fledged
- PostScript interpreter, which is beyond the scope of this
- package. However, see the psidtopgm tool, which can read
- grayscale non-runlength PostScript image data. Also, if
- you're willing to install the fairly large GhostScript
- package, it comes with a pstoppm script.
-
- OPTIONS
- The -scale flag controls the scale of the result. The
- default scale is 1, which on a 300 dpi printer such as the
- Apple LaserWriter makes the output look about the same size
- as the input would if it was displayed on a typical 72 dpi
- screen. To get one PNM pixel per 300 dpi printer pixel, use
- "-scale 0.25".
-
- The -rle or -runlength flag specifies run-length
- compression. This may save time if the host-to-printer link
- is slow; but normally the printer's processing time
- dominates, so -rle makes things slower.
-
- The -dpi flag lets you specify the dots per inch of your
- output device. The default is 300 dpi. In theory
- PostScript is device-independent and you don't have to worry
- about this, but in practice its raster rendering can have
- unsightly bands if the device pixels and the image pixels
- aren't in sync.
-
- The -width and -height flags let you specify the size of the
- page. The default is 8.5 inches by 11 inches.
-
- All flags can be abbreviated to their shortest unique
- prefix.

- BUGS
- It ought to automatically rotate to landscape mode if that
- would fit the image better.
