Member Function Documentation

bool lti::medianCut::apply	(	const image &	src,
		image &	dest,
		palette &	thePalette
	)			const

This apply method calculates a a quantized image and respective palette.

Parameters:

	src	image with the source data.
	dest	color quantized image
	thePalette	color palette used

bool lti::medianCut::apply	(	const image &	src,
		image &	dest
	)			const [virtual]

This apply method calculates a quantized image (on copy).

Parameters:

	src	image with the source data.
	dest	image where the result will be left.

Returns:

true if successful, false otherwise

Reimplemented from lti::colorQuantization.

bool lti::medianCut::apply

(

image &

srcdest

)

const [virtual]

This apply method calculates a quantized image (on place).

Parameters:

srcdest

image with the source data. The result will be left here too.

Returns:

true if successful, false otherwise

Reimplemented from lti::colorQuantization.

bool lti::medianCut::apply	(	const image &	src,
		channel8 &	dest,
		palette &	thePalette
	)			const [virtual]

This apply method calculates a channel8, containing the indices of the quantized colors AND the palette.

Will deliver empty channel8, if more than 256 colors!! But palette will be O.K.

Parameters:

	src	image with the source data.
	dest	channel8 where the result will be left.
	thePalette	palette appendant to dest.

Returns:

true if successful, false otherwise

Implements lti::colorQuantization.

bool lti::medianCut::apply	(	const image &	src,
		channel8 &	dest
	)			const

This apply method calculates a channel8, containing the indices of the quantized colors.

Will deliver empty channel8, if more than 256 colors!!

Parameters:

	src	image with the source data.
	dest	channel8 where the result will be left.

Returns:

true if successful, false otherwise

virtual functor* lti::medianCut::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::colorQuantization.

medianCut& lti::medianCut::copy

(

const medianCut &

other

)

copy data of "other" functor.

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::colorQuantization.

const parameters& lti::medianCut::getParameters

(

)

const

returns used parameters

Reimplemented from lti::colorQuantization.

virtual const char* lti::medianCut::getTypeName

(

)

const [virtual]

returns the name of this type ("medianCut")

Reimplemented from lti::colorQuantization.
