Function Documentation

exportFIT()

void exportFIT	(	const std::string &	filename,
		const std::map< std::string, bsdf_ptr< CONF > > &	data,
		const std::string &	comment
	)

Export a 'fit' file.

Parameters

filename	= FIT filename to write to
data	= std::map<std::string, bsdf_ptr> of fitted data
comment	= string of comment to add to the start of the fit file (ignored if empty)

exportPFM()

void exportPFM	(	const std::string &	filename,
		const bitmap< T > &	data,
		const std::array< ptrdiff_t, 3 > &	channels = {0,1,2}
	)

Export a bitmap to a PFM.

Parameters

filename	= PFM filename to write to.
data	= bitmap to export
channels	= which channels to export to the PFM file (default {0,1,2}) use -1 to ignore (write 0)

Write a bitmap to a 3-channel little endian PFM file. Allows the selection of channels to write out in case the bitmap contains more (or less) than 3 channels.

importFIT()

void importFIT	(	const std::string &	filename,
		std::map< std::string, bsdf_ptr< CONF > > &	data
	)

Import a 'fit' file.

Parameters

filename	= FIT filename to read from
data	= std::map<std::string, bsdf_ptr> to store the fit data to

importPFM()

void importPFM	(	const std::string &	filename,
		bitmap< T > &	data,
		const std::array< ptrdiff_t, N > &	channels = {0,1,2}
	)

Import a bitmap from a PFM.

Parameters

filename	= PFM filename to read from
data	= bitmap store the data in
channels	= which channels in data to fill (default {0,1,2}; use -1 to ignore a channel from the PFM)

Read a bitmap from a PFM file (1 and 3 channels as well as little and big endian PFMs are supported). Allows the selection of channels to write out in in the bitmap.
