Detailed Description

Functor to save a Protable Network graphic (PNG) file.

To save a PNG image just initialize the parameters of the "savePNG" object and call the apply member.

Example:

 lti::image anImg;                      // an image
 ...
 lti::savePNG saveImg;                  // the save functor
 lti::savePNG::parameters param;        // functor parameters
 param.filename = "~/tmp/theFile.png";  // name of the PNG file
 saveImg.setParameters(param);          // set the functor parameters
 saveImg.apply(anImg);                  // save the file

You can also use the more confortable shortcut:

 lti::image anImg;                      // an image
 ...
 lti::savePNG saveImg;                  // the save functor
 saveImg.save("~/tmp/theFile.png",img); // save the image.

Member Function Documentation

bool lti::savePNG::apply	(	const channel8 &	theChannel,
		const lti::palette &	colors = emptyPalette
	)			[virtual]

save 8-bit channel as 24-bbit RGB by assigning each R, G and B the same grey-value

Reimplemented from lti::ioFunctor.

bool lti::savePNG::apply

(

const channel &

theChannel

)

[virtual]

save float channel as grey image

Reimplemented from lti::ioFunctor.

bool lti::savePNG::apply

(

const image &

theImage

)

[virtual]

save image as PNG

Reimplemented from lti::ioFunctor.

virtual functor* lti::savePNG::clone

(

)

const [virtual]

returns a pointer to a clone of the functor.

Implements lti::functor.

virtual const char* lti::savePNG::getTypeName

(

)

const [virtual]

returns the name of this type

Reimplemented from lti::ioPNG.

bool lti::savePNG::save	(	const std::string &	filename,
		const channel &	theChannel
	)

save a channel as a grey image (0 = Black, 1 = White) the given color palette

bool lti::savePNG::save	(	const std::string &	filename,
		const channel8 &	theChannel,
		const lti::palette &	colors = emptyPalette
	)			[virtual]

save an "indexed" image contained in the given channel8 (indices) and the given color palette

Reimplemented from lti::ioFunctor.

bool lti::savePNG::save	(	const std::string &	filename,
		const image &	theImage
	)			[virtual]

this will save an image as a 24 bit RGB bitmap image

Reimplemented from lti::ioFunctor.
