Detailed Description

template<class StorageType>
class BIAS::ConvertHDR< StorageType >

This class handles conversions of HDR images to for example unsigned char.

Needed for some tools and displaying HDR images. In the future this class will be expanded to incorporate white balance and gamma functions

Member Function Documentation

template<class StorageType >

int BIAS::ConvertHDR< StorageType >::ToUnsignedChar	(	BIAS::Image< StorageType > &	src,
		BIAS::Image< unsigned char > &	dst
	)

simple conversion to unsigned char, assumed bit depth is 16 -> all pixel values are divided by 65535 supports unsigned short int images.

deprecated, use other method

template<class StorageType >

int BIAS::ConvertHDR< StorageType >::ToUnsignedCharGamma	(	BIAS::Image< StorageType > &	src,
		BIAS::Image< unsigned char > &	dst,
		float	gamma,
		unsigned int	currentMaxVal
	)

Conversion to unsigned char image, leaves min/max part intact.

Parameters

gamma	= gamma value for gamma correction (gamma = 1 means no gamma correction)
currentMaxVal	= current maximun possible value - caused by bit depth for example bit depth 12 means a currentMaxVal of 4095 the actual min and max values of the image are incorporated, meaning, the image is not stretched to fill the whole range of values between 0 and 255.
