SYNOPSIS

       vcrop [-option ...] [infile] [outfile]

DESCRIPTION

       vcrop  crops  a  file of images using a cropping rectangle specified by
       command line options.

COMMAND LINE OPTIONS

       vcrop accepts the following options:

       -help          Prints a message describing options.

       -in infile     Specifies a Vista data file containing the input images.

       -out outfile   Specifies where to write the cropped images as  a  Vista
                      data file.

       -top row       Specifies the first (top) row of the cropping rectangle.

       -bottom row    Specifies   the   last  (bottom)  row  of  the  cropping
                      rectangle.

       -left col      Specifies the first (leftmost) column  of  the  cropping
                      rectangle.

       -right col     Specifies  the  last  (rightmost) column of the cropping
                      rectangle.

       -height nrows  Specifies the height of the cropping rectangle.

       -width ncols   Specifies the width of the cropping rectangle.

       The cropping rectangle must be unambiguously specified by using any two
       of  -top,  -bottom,  and  -height,  plus  any two of -left, -right, and
       -width.

       The cropping rectangle may fall  partially  or  completely  outside  an
       image  it  is  cropping;  in that case, the area outside is filled with
       zeros.

       Input and output files can be specified on the command line or  allowed
       to default to the standard input and output streams.
