- NAME
- pnmtops - convert portable anymap to PostScript
-
- SYNOPSIS
- pnmtops [-scale s] [-turn|-noturn] [-rle|-runlength] [-dpi
- n] [-width n] [-height n] [-center|-nocenter] [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 -turn and -noturn flags control whether the image gets
- turned 90 degrees. Normally, if an image is wider than it
- is tall, it gets turned automatically to better fit the
- page. If the -turn flag is specified, it will be turned no
- matter what its shape; and if the -noturn flag is specified,
- it will not be turned no matter what its shape.
-
- 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.
-
- With the -nocenter flag, the output is not centered on the
- page, i.e. it appears in the upper left corner. This is
- useful for programs which can include PostScript files, but
- can't cope with pictures which are not positioned in the
- upper left corner. The default is -center i.e. the image is
- centered on the page.
-
- All flags can be abbreviated to their shortest unique
- prefix.
