SYNOPSISvinvert [option ...] [infile] [outfile]
DESCRIPTIONvinvert 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 OPTIONSvinvert accepts the following options:
- 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.
