Detailed Description

A kernel described by a function.

The function's x, y arguments are as follows:

Note: each pixel is set to the value of the kernel function at the center of the pixel (rather than averaging the function over the area of the pixel).

boost::shared_ptr< afwMath::Kernel > lsst.afw.math::AnalyticKernel::clone ( ) const

Return a pointer to a deep copy of this kernel.

This kernel exists instead of a copy constructor so one can obtain a copy of an actual kernel instead of a useless copy of the base class.

Every kernel subclass must override this method.

) const

Compute an image (pixellized representation of the kernel) in place.

This special version accepts any size image (though you can get in trouble if the image is large enough that the image is evaluated outside its domain).

x, y are ignored if there is no spatial function.

Returns

Exceptions

Parameters

doNormalizenormalize the image (so sum is 1)?
