Define Documentation

#define SET_SAMPLE	(	s,
		p,
		x,
		y,
		w,
		v		)

Value:

if ( (p) == SINGLE_PRECISION )              \
{                                           \
   ((float*)s)[(y)*(w)+(x)] = (float)(v);   \
}                                           \
else                                        \
{                                           \
   ((double*)s)[(y)*(w)+(x)] = (double)(v); \
}

Convenience macro for accessing a sample plane with the required precision.

Parameters:

	s	Sample plane ("planes[color]" in convertToPlanar context)
	p	precision ("precision" in convertToPlanar context)
	x	X coordinate of pixel
	y	Y coordinate of pixel
	w	The pixels line width of the samples buffer ("lineW" in convertToPlanar context)
	v	The value to store in the output buffer

Enumeration Type Documentation

enum floating_precision_t

Floating point precision of images.

This protocol will be conformed to, by the classes which implements the processing of an image or a list of images.

---

Function Documentation

void initializeProcessing

(

)

Processing initialization.

Returns:

None

To initialize the processing, we need to check if the processor support Altivec instructions and configure FFTW3 calls accordingly ; and then to retrieve the number of processors.
