NAME

       pfspad - Add borders to a frame in PFS stream

SYNOPSIS

       pfspad  [--left	<columns>]  [--right <columns>] [--top <rows>] [--bottom <rows>] [--width <new_width>] [--height <new_height>] [--R <val>]
       [--G <val>] [--B <val>] [--Y <val>] [--help]

DESCRIPTION

       Add borders to each frame in PFS stream. User specifies size of left, right, top and bottom border or size of an  output  image.  Color	of
       borders can be specified as well.

OPTIONS

       --left <columns>, -l <columns>
	      Width in pixels of the left border.

       --right <columns>, -r <columns>
	      Width in pixels of the right border.

       --top <rows>, -t <rows>
	      Height in pixels of the top border.

       --bottom <rows>, -b <rows>
	      Height in pixels of the bottom border.

       --width <new_width>, -W <new_width>
	      Width of an output image. Note that --width can be mixed with either --left or --right option.

       --height <new_height>, -H <new_height>
	      Height of an output image. Note that --height can be mixed with either --top or --bottom option.

       --R <val>, -R <val>, --G <val>, -G <val>, --B <val>, -B <val>
	      Color of borders in RGB mode. Default color is black, and if some of the components is not specified, its value is set to 0.0.

       --Y <val>, -Y <val>
	      Color of borders in luminance mode.

       --help, -h
	      Print a list of commandline options.

EXAMPLES

       pfsin image.hdr | pfspad --left 50 --bottom 20 | pfsout out.hdr
	      Add 50 columns to the left and 20 rows to the bottom side of image.hdr.  Color of borders is default black.

       pfsin image.hdr | pfspad --top 20 --height 500 --width 400 --R 1.0 | pfsout out.hdr
	      Add 20 rows to the top side of image.hdr and create output image out.hdr 500 pixels in height and 400 pixels in width. Color of bor-
	      ders is set to red.

NAME

       pamcut - cut a rectangle out of a PAM, PBM, PGM, or PPM image

SYNOPSIS

       pamcut  [-left  leftcol] [-right rightcol] [-top toprow] [-bottom bottomrow] [-width width] [-height height] [-pad] [-verbose] [ left right
       width height ] [pnmfile]

       All options may be abbreviated to the shortest unique prefix.

DESCRIPTION

       Reads a PAM, PBM, PGM, or PPM image as input.  Extracts the specified rectangle, and produces the same kind of image as output.

       There are two ways to specify the rectangle to cut: arguments and options.  Options are easier to remember and read, more  expressive,  and
       allow you to use defaults.  Arguments were the only way available before July 2000.

       If you use both options and arguments, the two specifications get mixed in an unspecified way.

       To  use	options, just code any mixture of the -left, -right, -top, -bottom, -width, and -height options.  What you don't specify defaults.
       It is an error to overspecify, i.e. to specify all three of -left, -right, and -width or -top, -bottom, and -height.

       To use arguments, specify all four of the left, right, width, and height arguments.  left and top have the same effect as  specifying  them
       as  the	argument  of  a -left or -top option, respectively.  width and height have the same effect as specifying them as the argument of a
       -width or -height option, respectively, where they are positive.  Where they are not positive, they have the same effect as specifying  one
       less  than  the	value  as  the argument to a -right or -bottom option, respectively.  (E.g.  width = 0 makes the cut go all the way to the
       right edge).  Before July 2000, negative numbers were not allowed for width and height.

       Input is from Standard Input if you don't specify the input file pnmfile.

       Output is to Standard Output.

OPTIONS

       -left  The column number of the leftmost column to be in the output.  If a nonnegative number, it refers to columns numbered from 0 at  the
	      left, increasing to the right.  If negative, it refers to columns numbered -1 at the right, decreasing to the left.

       -right The column number of the rightmost column to be in the output, numbered the same as for -left.

       -top   The  row	number	of  the  topmost  row  to be in the output.  If a nonnegative number it refers to rows numbered from 0 at the top,
	      increasing downward.  If negative, it refers to columns numbered -1 at the bottom, decreasing upward.

       -bottom
	      The row number of the bottom-most row to be in the output, numbered the same as for -top.

       -width The number of columns to be in the output.  Must be positive.

       -height
	      The number of rows to be in the output.  Must be positive.

       -pad   If the rectangle you specify is not entirely within the input image, pamcut fails unless you also specify -pad.  In  that  case,	it
	      pads  the output with black up to the edges you specify.	You can use this option if you need to have an image of certain dimensions
	      and have an image of arbitrary dimensions.

	      pnmpad also adds borders to an image, but you specify their width directly.

       -verbose
	      Print information about the processing to Standard Error.
