Detailed Description

Split image in its Red - Green - Blue channels.

You can split all the channels at the same time (with apply) or get just one channel using the shortcut functions getRed(), getGreen() or getBlue().

channel8 &  green,
channel8 &  blue 
) const [virtual]

split the image in red green and blue channels.

The values of each pixel will be between 0 and 255

Parameters:
img the image to be splitted
red the red channel
green the green channel
blue the blue channel
Returns:
true if successful, false otherwise.

Implements lti::splitImage.

virtual bool lti::splitImageToRGB::apply ( const image &  img,
channel &  red,
channel &  green,
channel &  blue,
channel &  alpha 
) const [virtual]

split the image in red green and blue channels.

The values of each pixel will be between 0.0f and 1.0f

Parameters:
img the image to be splitted
red the red channel
green the green channel
blue the blue channel
alpha or dummy channel
Returns:
true if successful, false otherwise.
virtual bool lti::splitImageToRGB::apply ( const image &  img,
channel &  red,
channel &  green,
channel &  blue 
) const [virtual]

Split the image in red green and blue channels.

The values of each pixel will be between 0.0f and 1.0f

Parameters:
img the image to be splitted
red the red channel
green the green channel
blue the blue channel
Returns:
true if successful, false otherwise.

Implements lti::splitImage.

virtual functor* lti::splitImageToRGB::clone (  )  const [virtual]

returns a pointer to a clone of the functor.

Implements lti::functor.

bool lti::splitImageToRGB::getBlue ( const image &  img,
channel8 &  blue 
) const

shortcut to get the red channel only The values of each pixel will be between 0 and 255

Parameters:
img the image to be splitted
blue the blue channel
bool lti::splitImageToRGB::getBlue ( const image &  img,
channel &  blue 
) const

shortcut to get the red channel only The values of each pixel will be between 0.0f and 1.0f

Parameters:
img the image to be splitted
blue the blue channel
virtual bool lti::splitImageToRGB::getFirst ( const image &  img,
channel8 &  c1 
) const [virtual]

Returns the first of the three channels into which the image is split.

If you need only one channel, this might be faster than calling apply().

Parameters:
img the source image
c1 the extracted channel

Reimplemented from lti::splitImage.

virtual bool lti::splitImageToRGB::getFirst ( const image &  img,
channel &  c1 
) const [virtual]

Returns the first of the three channels into which the image is split.

If you need only one channel, this might be faster than calling apply().

Parameters:
img the source image
c1 the extracted channel

Reimplemented from lti::splitImage.

bool lti::splitImageToRGB::getGreen ( const image &  img,
channel8 &  green 
) const

shortcut to get the green channel only The values of each pixel will be between 0 and 255

Parameters:
img the image to be splitted
green the green channel
bool lti::splitImageToRGB::getGreen ( const image &  img,
channel &  green 
) const

shortcut to get the red channel only The values of each pixel will be between 0.0f and 1.0f

Parameters:
img the image to be splitted
green the green channel
bool lti::splitImageToRGB::getRed ( const image &  img,
channel8 &  red 
) const

shortcut to get the red channel only The values of each pixel will be between 0 and 255

Parameters:
img the image to be splitted
red the red channel
bool lti::splitImageToRGB::getRed ( const image &  img,
channel &  red 
) const

shortcut to get the red channel only The values of each pixel will be between 0.0f and 1.0f

Parameters:
