Detailed Description

Gamma-correct an Image with a GammaCurve.

A suitable GammaCurve can be calculated automatically from a Histogram. For instance:

 typedef Image<RGBPixel<unsigned short> > ImageType;
 ImageType image;
 // ... fill in image ...
 Histogram<ImageType, 3> histogram(image);
 GammaCurve<ImageType::ValueType> gammaCurve(histogram);
 GammaFilter gammaFilter;
 gammaFilter.filter(image, gammaCurve);

Examples:

util/raw2ppm.cc.

Member Function Documentation

template<typename ImageType , typename GammaCurveType >

void refinery::GammaFilter::filter	(	ImageType &	image,
		const GammaCurveType &	gammaCurve
	)

Gamma-correct image using gammaCurve.

This ought to be a 1-param template but Swig can't resolve it.

Parameters:

[in,out]	image	Image to gamma-correct.
[in]	gammaCurve	Gamma curve to apply.

Template Parameters:

ImageType	Image type (can be inferred).
GammaCurveType	Gamma-curve type (can be inferred).

Examples:

util/raw2ppm.cc.
