SYNOPSISpnmpad [-verbose] [-white|-black]
[[[-width=width [-halign=ratio]] |
[-left=leftpad] [-right=rightpad]]]
[[[-height=height [-valign=ratio]] |
[-top=toppad] [-bottom=botpad]]]
[pnmfile]
All options can be abbreviated to their shortest unique
prefix. You may use two hyphens instead of one to desig
nate an option. You may use either white space or an
equals sign between an option name and its value.
DESCRIPTION
Reads a PNM image as input. Outputs a PNM image that is
the input image plus black or white borders of the sizes
specified.
If you just need to convert an image to a certain size
regardless of the original dimensions, pnmcut with the
-pad option may be a better choice.
OPTIONS-verbose
Verbose output.
-white
-black (default)
Set pad color.
-left leftpad
-right rightpad
-top toppad
-bottom bottompad
Specify amount of padding in pixels.
-width width
Set desired width of image. Overrides -left and
-right if specified. If width is less than the
actual image width, it is ignored. Use pnmcut(1) to
cut off parts of images.
-height height
Set desired height of image. Overrides -top and
-bottom if specified. If height is less than the
actual image height, it is ignored. Use pnmcut(1)
to cut off parts of images.
-halign ratio
A real number between 0 and 1. Used in conjunction
with -width, sets the alignment ratio between left
padding and right padding.
Useful values:
0.0 - left aligned;
0.5 - center aligned (default);
1.0 - right aligned.
-valign ratio
A real number between 0 and 1. Used in conjunction
with -height, sets the alignment ratio between bot
tom padding and top padding.
Useful values:
0.0 - bottom aligned;
0.5 - center aligned (default);
1.0 - top aligned.
HISTORY
Before February 2002,
pnmpad had a different option syntax which was less
expressive and not like conventional Netpbm pro
grams. That syntax is still understood by pnmpad
for backward compatibility, but not documented or
supported for future use.
