vinvert

vinvert(1Vi)															      vinvert(1Vi)

NAME

       vinvert - invert image pixel values

SYNOPSIS

       vinvert [option ...] [infile] [outfile]

DESCRIPTION

       vinvert inverts each input image to produce a corresponding output image. The operation is suitable for swapping black and white in a grey-
       scale image.

       Each output pixel is computed from the corresponding input pixel by

	      out-pixel = M - in-pixel

       where M is the maximum value allowed by the pixel representation, or 1 in the case of float or double pixels. Input pixel values  must  lie
       in the range [0,M].

       Each output image has the same number of bands, rows and columns, and the same pixel representation, as the corresponding input image.

COMMAND LINE OPTIONS

       vinvert 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 output images as a Vista data file.

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