The ImageMagick convert tool can be used to negate an image using the -negate
and +negate
options. -negate
replaces every grayscale or RGB pixel with its inverted or complementary color. Use +negate
when you want to restrict this operation to only work on grayscale pixels.
Example:
$ convert -negate foo.png inverted_foo.png
Tried with: ImageMagick 6.9.7 and Ubuntu 18.04
