Member Function Documentation

std::string JpegParser::getComments

(

)

const [virtual]

Get the comments from the image without fully reading it.

Implements RasterParser.

)

const [virtual]

Get the specifications of the image without fully reading it.

Implements RasterParser.

bool JpegParser::getTag	(	uint	tag,
		std::string &	name,
		std::string &	value
	)			const [virtual]

Get image tags if the image supports them.

Implements RasterParser.
