Detailed Description

template<typename T, std::size_t NFrom, std::size_t NTo>
class refinery::ColorConverter< T, NFrom, NTo >

Converts from one color space to another.

Example:

 float conversionMatrix[3][4]; // e.g. CMYK to RGB
 // ... fill in conversionMatrix ...
 ColorConverter<float, 4, 3> converter(conversionMatrix);
 CMYKPixel<float>* in;
 RGBPixel<float>* out;

 for (in = firstPixel; in < lastPixel; in++, out++) {
   converter.convert(in->constArray(), out->array());
 }

Template Parameters:

T	Type of conversion matrix (usually float or double).
NFrom	Arity of source arrays.
NTo	Arity of destination arrays.

template<typename U , typename V >

void refinery::ColorConverter< T, NFrom, NTo >::convert	(	const U(&)	in[NFrom],
		V(&)	out[NTo]
	)		[inline]

Convert an input vector to an output one.

Template Parameters:

U	Datatype of input vector (usually inferred).
V	Datatype of output vector (usually inferred).

Parameters:

[in]	in	Vector with NFrom input colors.
[out]	out	Vector with NTo output colors.

template<typename T , std::size_t NFrom, std::size_t NTo>

template<typename U , typename V >

void refinery::ColorConverter< T, NFrom, NTo >::convert	(	const U(&)	in[NFrom-1],
		V(&)	out[NTo]
	)		[inline]

Convert an undersized input vector to an output one.

We need this special case, because we sometimes treat all cameras as having 4-color sensor arrays when they actually have 3, but at other times we optimize away the final element. Usually users won't need to directly specify this method.

Template Parameters:

U	Datatype of input vector (usually inferred).
V	Datatype of output vector (usually inferred).

Parameters:

[in]	in	Vector with NFrom input colors.
[out]	out	Vector with NTo output colors.
