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. SEE ALSO
