procedure Expand(Src, Dst: TBitmap32; Kernel: TIntegerMap; CenterX, CenterY: Integer);

Description

Expand performs rasterization using the TExpander sampler. The Kernel parameter specifies a weight matrix which is centered at the coordinated (X + CenterX, Y + CenterY) for each pixel coordinate (X, Y).

Output pixels are computed from the formula

where f corresponds to the source bitmap and b corresponds to the kernel (formally described as a structuring element).
