Detailed Description

Interfaces the OpenEXR library with the Imageutilities.

Constructing an OpenEXROutputFile requires the filename and image size. Data is added through various add_channel and add_attribute methods. Note that write has to be called explicitly to write the data to disk.

Todo:

what happens if write is called multiple times?

Constructor & Destructor Documentation

iu::OpenEXROutputFile::OpenEXROutputFile	(	const std::string &	filename,
		iu::Size< 2 >	size
	)

OpenEXROutputFile constructor. Opens a file for writing.

Parameters

filename	name of the file.
size	size of the image.
