PROGRAM
     vexpand - Expand an image by pixel replication

SYNTAX
     vexpand

     -i             input image

     -o             resulting expanded image

     [-s]           expansion scale factor

     [-V]           Gives the version for vexpand

     [-U]           Gives the usage for vexpand

     [-P]           Prompts for command line options

     [-A [file1]]   Creates the answer file called vexpand.ans or
                    file1

     [-a [file1]]   Uses vexpand.ans or file1 as the answer file

DESCRIPTION
     vexpand expands the size of an image by an integer factor by
     replicating pixels in blocks.

     A cute "high-tech" image can be made by first vshrink(1)'ing
     an image severely and then vexpand(1)'ing it back by the
     same scale factor.  This give the classic "cubist" picture.

     The scale factor must be a positive, non-zero integer.

     For a more control in resizing images, look at vresize(1).

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -o     type: outfile
            desc: resulting expanded image

OPTIONAL ARGUMENTS
     -s     type: integer
            desc: expansion scale factor
            default: 2
            bounds: value > 0

EXAMPLES
     vshrink -i feath.xv -o - -s 8| vexpand -i - -o cubist.xv -s
     8

     produces a modern looking cubist rendition of the pretty
     girl.
