Description
-
The vinvert program inverts an image (swapping black and white). vinvert inverts each input image to produce a corresponding output image. The opera tion 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.
