Detailed Description

This class handles reading/parsing of PFM image files.

PFM is an unofficial format that looks very much like PGM except that raw pixel values are floats. Caution, this is not portable across endianness. The PNM magic for this unofficial format is PF.

Member Function Documentation

string PfmParser::getComments

(

)

const [virtual]

Get the comments from the image without fully reading it.

Implements RasterParser.

Definition at line 141 of file PfmParser.C.

GenericFrame PfmParser::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 PfmParser::getFrameSpec

(

)

const [virtual]

Get the specifications of the image without fully reading it.

Implements RasterParser.

Definition at line 127 of file PfmParser.C.

References GenericFrame::GRAY_F32.

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

Get image tags if the image supports them.

Implements RasterParser.

uint PfmParser::getTagCount

(

)

const [virtual]

Get image tags if the image supports them.

Implements RasterParser.
