    pnmcut

    
    
    

    SYNOPSIS

           pnmcut [-left leftcol] [-right rightcol] [-top toprow] [-bottom bottom-
           row] [-width width] [-height height] [-pad] [-verbose] [ left top width
           height ] [pnmfile]
    
           All options may be abbreviated to the shortest unique prefix.
    
    
    

    DESCRIPTION

           Reads  a PBM, PGM, or PPM image as input.  Extracts the specified rect-
           angle, 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, -bot-
           tom, -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, top, 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  pnm-
           file.
    
           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
                  image, pnmcut 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  can also fill an image out to a specified dimension, and
                  gives you more explicit control over the padding.
    
           -verbose
                  Print information about the processing to Standard Error.
