template<typename I >

mln::trait::concrete< I >::ret mln::world::rgb::invert

(

const Image< I > &

input

)

[inline]

Point-wise reversion of image input.

Parameters:

[in]

input

the input image.

Returns:

The result image.

Precondition:

input.is_valid

It performs:
for all p of input.domain
{
output(p).red() = min(red) + (max(red) - input(p).red())
output(p).green() = min(green) + (max(green) - input(p).green())
output(p).blue() = min(blue) + (max(blue) - input(p).blue())
}

template<typename I >

void mln::world::rgb::invert_inplace

(

Image< I > &

input

)

[inline]

Point-wise in-place reversion of image input.

Parameters:

[in,out]

input

The target image.

Precondition:

input.is_valid

It performs:
for all p of input.domain
{
output(p).red() = min(red) + (max(red) - input(p).red())
output(p).green() = min(green) + (max(green) - input(p).green())
output(p).blue() = min(blue) + (max(blue) - input(p).blue())
