Member Function Documentation

template<ImageFormat FORMAT0, ImageFormat FORMAT1>

Image<FORMAT1>::PixelType dlr::computerVision::ColorspaceConverter< FORMAT0, FORMAT1 >::operator()

(

const typename Image< FORMAT0 >::PixelType &

inputPixel

)

[inline]

The application operator does the format conversion for one pixel.

We somewhat awkwardly dispatch to the two-argument application operator because of the unfortunate way we've had to declare the non-scalar pixel types. The non-scalar pixel types are declared as structs with C linkage so we can guarantee their layout in memory. I don't know of a way to return a filled-in C struct which takes advantage of the return value optimization, so we provide the two-argument version of operator()() in order to sidestep the problem. The single-argument version dispatches to the two-argument version to avoid code duplication, which makes it slightly slower than it could be for scalar types.

Parameters:

inputPixel

The pixel to be converted.

Returns:

The return value is the converted pixel.

template<ImageFormat FORMAT0, ImageFormat FORMAT1>

void dlr::computerVision::ColorspaceConverter< FORMAT0, FORMAT1 >::operator()	(	const typename Image< FORMAT0 >::PixelType &	inputPixel,
		typename Image< FORMAT1 >::PixelType &	outputPixel
	)			[inline]

The application operator does the format conversion for one pixel, returning the result through a reference argument.

This is the fastest way to do a pixel conversion.

Parameters:

	inputPixel	The pixel to be converted.
	outputPixel	This reference argument is set to the result of the conversion.
