	)		const

inline

Interpolate the data item at a non-integer position x, y.

It checks if the interpolation would access a pixel with alpha = 0 and returns false in that case.

be careful, no bounds checking is done here. take INTERPOLATOR::size into accout before iterating over the picture.

the used image pixels are [i-(n/2 -1) .. i+n/2], where n is the size of the interpolator

Parameters

x	x position, relative to `i` and `alpha.first`
y	y position, relative to `i` and `alpha.first`
result	the interpolation result

Returns: true if interpolation ok, false if one or more pixels were masked out
