Namespace Convolve2d

Performs kernel-based convolution over image.

Performs kernel-based convolution over a grid, mutating the source grid with the results.

For a given kernel, returns an array of offsets. These consist of a cell offset (eg {x:-1,y:-1}) and the value at that kernel position.

Multiply every element of kernel by the same scalar value. Returns new result, input is unmodified

Reduces an array of values to a single value. Returns undefined if no values are present.
