struct ConvolutionKernelPredefined convolution kernels. These approximations of the Gaussian kernels below are computed as a repeated convolution of the `[1 1]` box filter. They're identical to every other row of Pascal's triangle of the binomial coefficients. The kernel values have been normalized to sum to 1.0.
static get gaussian1Dx3(): Array<number>static let gaussian1Dx3: [Float]An array of that represents a three element 1D Gaussian kernel. Use this constant with the `separableConvolve` functions to perform fast Gaussian blur.
static get gaussian1Dx5(): Array<number>static let gaussian1Dx5: [Float]An array that represents a five element 1D Gaussian kernel. Use this constant with the `separableConvolve` functions to perform fast Gaussian blur.
static get gaussian1Dx7(): Array<number>static let gaussian1Dx7: [Float]An array that represents a seven element 1D Gaussian kernel. Use this constant with the `separableConvolve` functions to perform fast Gaussian blur.
