Member Function Documentation

std::string PngParser::getComments

(

)

const [virtual]

Get the comments from the image without fully reading it.

Implements RasterParser.

Definition at line 223 of file PngParser.C.

GenericFrame PngParser::getFrame

(

)

[virtual]

Get a GenericFrame representation from the raster file.

This can subsequently be converted to rgb, grayscale, floating-point, or video-yuv.

Implements RasterParser.

GenericFrameSpec PngParser::getFrameSpec

(

)

const [virtual]

Get the specifications of the image without fully reading it.

Implements RasterParser.

Definition at line 206 of file PngParser.C.

References GenericFrame::GRAY_U8, and GenericFrame::RGB_U8.

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

Get image tags if the image supports them.

Implements RasterParser.

Definition at line 231 of file PngParser.C.

uint PngParser::getTagCount

(

)

const [virtual]

Get image tags if the image supports them.

Implements RasterParser.
