vdump - convert VIPS image files to Postscript
vdump [ -slpDa
] filename
vdump turns the vasari format file in its argument
to encapsulated PostScript on its stadard output. The result can be either
sent directly to a printer or included in any document processor which
supports encapsulated PostScript diagrams - eg. WordPerfect, Tex etc. For
example:
- example% vdump campin.v | lpr -Plaser
or
- example% vdump -l -s4 -D
campin.v > campin.PS
vdump normally outputs portrait, you can force output to portrait or landscape
with the -p or -l flags.
The -a flag makes vdump select either portrait or landscape orientation
so as to get the largest possible image onto an A4 sheet.
vdump will dump one or three band unsigned char images only.
- -p
- Force
portrait output.
- -l
- Force landscape output.
- -a
- Automatically select portrait/landscape.
- -s<factor>
- Set a sub-sampling factor (default 1). -s1 will not sub-sample at all,
-s4 will reduce by a factor of 4.
- -D
- Produce output suitable for including
in documents. This option simply supresses the generation of a showpage
command.
